CP-1 KERATIN CONCENTRATE AMPOULE 80ML

Values: 100% Genuine (Adilsons policy) · FA-Conditional (see Sec 30B) · Not Fragrance-Free · Not currently badged Halal-Friendly or Vegan-Friendly (see Sec 26).

If your hair feels like straw by the time it dries in Mauritius humidity, that isn't just dryness — it's raised, damaged cuticle scattering light and snagging on itself, which is exactly what a protein-filling ampoule is built to smooth over.

Pros: No-rinse convenience, avoids-scalp design keeps it usable on oily scalps, small 80ml size suits testing before committing to a bigger bottle, layers under styling products. Caveats: Contains fragrance and three declared allergens, protein concentrations aren't disclosed, and overuse on fine/low-porosity hair can leave buildup (see Sec 35).

Compatibility checklist: Bedside-compatible (no sink needed) — yes, once hair is towel-dry. Requires rinsing — no. Requires precise dosage — no, a rough palmful works. Applicable with damp hands post-shower — yes. Requires wait time — no, style immediately after.

Minimum viable routine position: This qualifies as a single-step addition to a bare-bones routine: shampoo, this ampoule on the ends, done — no separate leave-in conditioner or serum required on a low-energy day.

Sensory note: The formula is watery, not tacky, so it doesn't discourage use the way a heavy balm might on a day you just want to get out of the shower and go.

Step 1 (When): After shampooing (and conditioner, if used), on towel-dried or damp hair — AM or PM, whichever wash you do.

Step 2 (How much): A rough palmful (roughly 2-4ml), scaled up for longer or thicker hair.

Step 3 (How): Rub between palms, smooth through mid-lengths and ends only, avoiding the roots and scalp, then style or air-dry as usual — no rinsing.

Introduce this as the ONLY new product in your routine. Wait a full 14 days before adding anything else. This isolation window ensures you can identify whether any reaction is caused by this specific product.

1. Shampoo (your regular CP-1 or other shampoo). 2. Conditioner, if part of your routine, rinsed out. 3. Towel-dry to damp, not dripping. 4. Apply CP-1 Keratin Concentrate Ampoule to mid-lengths and ends, avoiding roots/scalp. 5. Style (blow-dry, air-dry, or heat tools with a separate heat protectant).

In Mauritius' morning humidity, applying this ampoule before styling matters more than in a dry climate — smoothed-down cuticle resists picking up ambient humidity through the day, which is the main driver of midday frizz here.

1. Shampoo and rinse-out conditioner as usual. 2. Towel-dry. 3. Apply CP-1 Keratin Concentrate Ampoule to lengths and ends. 4. Either style normally and sleep with hair loosely braided or wrapped to reduce friction, or — for an intensive treatment night — leave it in overnight and shampoo it out the next morning.

There is no skin-cycling relevance here (this isn't a facial active), but the same "don't stack redundant protein steps" logic applies: don't layer this with a separate leave-in protein mask the same night — pick one.

Technique: Rub between palms first to distribute evenly, then smooth (don't scrub or rub vigorously into) mid-lengths and ends — friction on wet hair increases cuticle abrasion, the opposite of what this product is for.

Required skin/hair state: Towel-dried or damp hair, not soaking wet (excess water dilutes the product on contact) and not fully dry (absorption is faster into slightly open, damp cuticle).

Wait time: None required before styling — this is a no-rinse leave-in, so you can proceed straight to blow-drying or air-drying.

Hands deliver 100% of product; a cotton pad or brush distributes unevenly for this format, so use hands unless you're working it through with a wide-tooth comb for even distribution on longer hair.

This is an encyclopedia map of all product types. You do not use all of these daily. You select modules based on your skin state.

Global execution rules: Viscosity ladder: thinnest → thickest; water-phase before oil-phase; treatments before seals. Wait-time defaults: watery layers 10-20s; serum layers 30-60s; before sunscreen 10-15 min if going outdoors or applying makeup. Amount defaults (unless brand-specific instructions override): Watery toner/essence 5-8 drops per layer; Serum/ampoule 2-3 drops or 1 pump (face), add +1 drop for neck; Eye product ½ rice-grain per eye; Gel moisturizer 1-1.5 peas, Cream 1-2 peas; Occlusive seal rice-grain to pea-size max; Sunscreen 2-finger rule for face, +1 finger for neck. Skin state rules: hydrators best on slightly damp skin; retinoids best on fully dry skin; exfoliating acids on dry or lightly damp skin, keep to one lane. Hard cap rule: if the routine pills, stings, or feels heavy, reduce layers, not increase.

AM Maximum Stack (facial skincare, for reference): 1. Rinse/Gentle Cleanse (optional). 2. pH-Prep/Balancing Toner (optional). 3. Hydrating Toner Layers (1-3, optional). 4. Essence (optional). 5. Mist/Thermal Water (optional). 6. Booster/Soothing Serum (optional). 7. Antioxidant Lane (choose one). 8. Pigment Support Lane (choose one). 9. Hydration Serum Lane (optional). 10.

Moisturizer. 11. Sleeping Mask (optional). 12. Occlusive Seal (optional). 13. Spot Treatment/Pimple Patch (as needed). 14. Lip Sleeping Mask (optional). Do not layer retinoids with AHA/BHA in the same night; keep "one lane" per night.

Where this product sits: The Keratin Concentrate Ampoule is a haircare leave-in, not a facial skincare step, so it doesn't occupy a rung on the maps above — see Section 20 (Hair and Scalp Compatibility) for its actual placement in a hair-wash routine.

Lane strictness (applies across both maps): One-lane rule: Retinoid OR Exfoliation OR Strong Vitamin C (LAA) OR Acne-control active per routine; barrier/hydration can always accompany. If unsure: default to the safest lane — barrier/hydration — and reduce layers.

Tier: Water-thin ampoule — thinner than a cream conditioner, similar consistency to a facial essence.

Layering rule: Apply after rinse-out conditioner (thinner treatment after thicker rinse-off product is fine here because this is a leave-in applied post-rinse, not a pre-rinse layering step) and before any heat-protectant spray or styling cream, which typically sit on top as the final sealing layer.

Phase compatibility: This is a water-glycol phase formula (no oil phase, no silicones in the declared INCI) — it will not repel or separate from an oil-based styling serum applied afterward, but applying a heavy oil first would block this ampoule's absorption into the cuticle.

Hair is non-living keratin, so there is no "epidermal turnover" equivalent here — every gain from this product is a surface/cuticle-level protein deposit that washes away gradually and needs reapplication, not a one-time structural repair.

Prerequisites: Before starting this product, you should already be using a compatible shampoo (sulfate-free or gentle) and, ideally, a rinse-out conditioner — a protein-filling leave-in on top of a harsh, stripping shampoo routine is working against itself.

This is a haircare product applied to hair strands, not skin — but the hairline and scalp margin are skin, so the "avoid scalp/roots" instruction on this product is itself a skin-contact consideration, particularly for anyone prone to scalp folliculitis or contact sensitivity to fragrance (see Section 24 for the declared allergens).

See Section 20 for the full hair-type (as opposed to scalp-skin) compatibility table.

Primary targets: Cuticle damage from heat styling, chemical colour, and UV exposure — Hydrolyzed Keratin and Keratin Amino Acids are small enough to bind into raised, damaged cuticle sites and temporarily patch them smooth. Frizz — a smoother cuticle surface reflects light more evenly and resists humidity-driven swelling.

Secondary benefits: Baobab seed extract, sesame seed extract, rice extract, and jojoba seed oil sit lower in the ingredient list as supporting conditioning/emollient agents, plausibly at trace levels (see Section 23's estimated 1% line).

What this product cannot do: It cannot repair split ends structurally (only trimming removes split ends — this smooths their appearance temporarily), cannot change your natural hair colour or texture, cannot reverse chemical damage that has already broken disulfide bonds (that needs a bond-repair treatment, not a protein filler), and cannot substitute for a healthy scalp-care routine if hair loss or scalp inflammation is the actual issue.

Complementary protein-lane shampoo (verified in-stock via Shopify on 2026-09-15) — primary pick: CP-1 Bright Complex Intense Nourishing Shampoo (Protein Shampoo), a sulfate-free protein-lane shampoo from the same brand that primes hair for this ampoule's protein deposition. Alternatives, all verified in stock: CP-1 Aquaxyl Complex Intense Moisture Shampoo 100ml (better if dryness, not damage, is the bigger issue), CP-1 Head Spa Cool Mint Shampoo 500ml (better for an oily, congested scalp paired with damaged ends), CP-1 Anti Hairloss Scalp Infusion Shampoo 250ml (if shedding is a concurrent concern; note this had only 1 unit in stock at last check).

Rinse-out conditioner to use beforehand — primary pick: CP-1 Ginger Purifying Conditioner 500ml. Two verified in-stock alternatives outside the CP-1 line: Medicube Rosemary PDRN Hair & Scalp Conditioner 250ml and Aromatica Rosemary Hair Thickening Conditioner 180ml. CP-1's own Aquaxyl and Bright Complex conditioners were out of stock at last check, so we're not listing them as a fourth option right now.

AM/PM usage note: Shampoo and conditioner first (either time of day), then this ampoule on damp lengths and ends, then style. No wait time is needed between these steps.

Permeability: Water-Permeable (wudu-compatible), with a caveat. The declared INCI contains no silicones (no dimethicone/amodimethicone/cyclopentasiloxane) and only a light cationic conditioning agent (Steartrimonium Chloride), so at the recommended light dose this does not form a heavy occlusive film on the hair shaft.

At the higher end of the dosage range on very long or thick hair, product can build a thin conditioning film that may slow water penetration to the hair surface during mash (wiping over the head) — if in doubt, a light rinse of the hair with water before wudu removes any doubt.

Adilsons provides this assessment based on the product's physical properties. Rulings on wudu validity vary between scholars. Consult your own trusted Islamic authority.

MYTH: "A 'keratin' hair product is the same as a salon keratin smoothing treatment." REALITY: Salon keratin smoothing treatments typically use heat and (historically) formaldehyde-releasing chemistry to permanently reshape the hair's internal bonds; this ampoule is a rinse-free topical protein filler that temporarily smooths cuticle — it will not straighten curl pattern.

MYTH: "More protein always means stronger, healthier hair." REALITY: Protein and moisture need to stay balanced — too much protein on already protein-saturated or low-porosity hair makes it feel stiff, straw-like, and prone to snapping rather than stronger (see Section 20).

MYTH: "If it doesn't rinse out, it's 'coating' my hair with something bad." REALITY: A leave-in protein treatment isn't inherently a coating agent — this formula has no silicone film-formers in its declared INCI, so it isn't sealing hair the way a silicone serum would.

Sugar cane burning season (Jul-Nov): PM2.5 particulate increases during this period. Because this formula is watery rather than tacky, it doesn't attract noticeably more airborne particulate than bare hair — no special adjustment needed, though rinsing hair after heavy outdoor exposure is generally sensible in this window regardless of product.

Hard water note: Mauritius tap water hardness varies by region; hard water leaves mineral buildup on hair that can make it feel dull and rough. The cationic conditioning agent in this formula (Steartrimonium Chloride) helps smooth over some of that roughness, but it doesn't remove mineral deposits — a clarifying shampoo every few weeks is the actual fix for hard-water buildup.

*Keratin Amino Acids, Hydrolyzed Wheat Protein, Hydrolyzed Elastin, and Hydrolyzed Collagen appear below the estimated 1% line in the INCI list, suggesting they are present at a trace/sub-efficacious concentration. Their inclusion may be primarily for marketing rather than clinical effect.

Full INCI list (sourced by cross-referencing multiple independent retailer listings; a single canonical brand-site or INCIDecoder page could not be directly fetched this session due to network restrictions, so treat this as medium- rather than high-confidence): Water, Butylene Glycol, Dipropylene Glycol, Glycerin, PEG-60 Hydrogenated Castor Oil, 1,2-Hexanediol, Myristyl Alcohol, CI 15985, Panthenol, Hydrolyzed Keratin, Caprylyl Glycol, [--- Estimated 1% Line ---] Adansonia Digitata (Baobab) Seed Extract, Steartrimonium Chloride, CI 19140, Propylene Glycol, Solanum Melongena (Eggplant) Fruit Extract, Sesamum Indicum (Sesame) Seed Extract, Oryza Sativa (Rice) Extract, Laminaria Japonica Extract, Glycine Max (Soybean) Seed Extract, Simmondsia Chinensis (Jojoba) Seed Oil, Keratin Amino Acids, Hydrolyzed Wheat Protein, Hydrolyzed Elastin, Glycyrrhiza Glabra (Licorice) Root Extract, Hydrolyzed Collagen, Glycine Soja (Soybean) Flour, Fragrance, Geraniol, Limonene, Linalool.

Preservative system: 1,2-Hexanediol and Caprylyl Glycol — a glycol-based multifunctional preservation system, rather than classic parabens or phenoxyethanol.

Fragrance status: Synthetic Fragrance (Parfum) — this is not a fragrance-free product.

Scent: Not independently smell-tested by us; expect a soft floral-leaning scent typical of Geraniol/Limonene/Linalool-based fragrance blends, based on the declared allergen profile.

EU 26 allergen screen: Geraniol, Limonene, and Linalool are all declared in the INCI and are on the EU 26 fragrance allergen list.

*Based on brand-declared INCI. The term "Fragrance" or "Parfum" in the INCI list may contain undisclosed allergens beyond Geraniol, Limonene, and Linalool. Patch test advised for sensitive individuals.

Alcohol disclosure: Contains Myristyl Alcohol at INCI position 7 (above the estimated 1% line) — this is a fatty alcohol, which is moisturizing/conditioning rather than drying, unlike SD alcohol or denatured alcohol.

Halal: We are not applying a Halal-Friendly badge to this product. The declared INCI contains Hydrolyzed Keratin, Hydrolyzed Collagen, and Hydrolyzed Elastin, all animal-derived, and no source species (bovine, porcine, marine, or poultry) is disclosed by any source we checked. Muslim customers who require certainty on animal source should treat this as an open question rather than assume a safe source, and may wish to consult their own scholar or contact us for what we do and don't know before purchasing.

Vegan: Not vegan. In addition to the undisclosed-source animal proteins above, this is a haircare category where CP-1's protein/repair lines routinely use animal-derived ingredients as core actives.

Cruelty-free: *No PETA Beauty Without Bunnies or Leaping Bunny listing was found for CP-1 or its parent company Esthetic House. Not independently certified by Leaping Bunny, PETA, or an equivalent third-party audit.

Microplastic-Free: Yes — no listed film-forming synthetic polymers or solid plastic particulates in the declared INCI.

MFDS classification: General Cosmetic. No evidence was found of Korean MFDS Functional Cosmetic registration for this product (Functional status requires additional government testing and applies mainly to whitening/wrinkle/UV-protection claims, none of which this product makes).

Mechanism claim: Hydrolyzed protein binding to damaged cuticle sites is a well-established mechanism in cosmetic science generally, but no brand-published clinical trial, sample size, or before/after study specific to this exact product was found.

*This product's repair claims are supported by general ingredient-class evidence rather than a study conducted on this specific formula — treat "repairs damaged hair" as a mechanism-based claim, not a clinically-proven-on-this-SKU one.

Fungal Acne Safety: FA-Conditional. Myristyl Alcohol (a C14 fatty alcohol) sits above the estimated 1% line and is commonly flagged on Malassezia-feeding ingredient reference lists. Since this product's own instructions already keep it off the scalp, the practical FA-relevance is low for typical use — but it is a reason not to deliberately apply this to a scalp with fungal-acne-prone (Malassezia folliculitis) skin.

Assessment: Low, for hair use as intended. Applied correctly (damp hair, light amount, hands not scrubbed), this water-thin formula does not pill.

Mitigation: If you use a heavy styling cream or oil immediately afterward without letting this ampoule absorb for a few seconds first, product can ball up at the ends — a brief pause before the next step avoids this.

Colour baseline: The formula contains cosmetic colorants (CI 15985, CI 19140), so expect a consistent tinted (yellow-to-amber-range) liquid; a sudden shift to a noticeably darker or murkier colour, or visible separation that doesn't remix, are signs to stop using it.

Storage: Keep out of direct sun and away from bathroom heat/humidity extremes where possible — Mauritius bathroom humidity accelerates degradation of glycol-based preservative systems faster than cool, dry storage.

Spoilage signs: Off/rancid smell replacing the fragranced scent, colour darkening significantly, or texture turning cloudy or separating and not remixing on shaking. When in doubt, discard.

Patch test: Apply a small amount to the inner forearm, wait 24 hours, then to skin behind the ear, wait another 24 hours, before your first full application to hair and hairline — this matters more than usual here given three declared fragrance allergens plus multiple protein ingredients with real allergenic potential (especially Hydrolyzed Wheat Protein, for anyone with a wheat/gluten sensitivity).

72-hour reset (if you react): If adverse reaction occurs: STOP ALL ACTIVES. For 72 hours, use ONLY a gentle shampoo and plain conditioner. After 72 hours, reintroduce one product per 14 days.

Emergency stop signals: Hives, swelling, blistering, persistent burning at the hairline/scalp margin, or breathing difficulty (seek emergency care immediately).

Top mistakes: 1. Applying to the scalp/roots — this product is formulated for lengths and ends only and will sit greasy at the roots if misapplied. 2. Overusing on fine or low-porosity hair — leads to stiffness and buildup rather than better results. 3. Applying to soaking-wet hair — excess water dilutes the product before it can bind to cuticle. 4. Stacking with another leave-in protein product the same wash — redundant, not additive. 5. Expecting it to fix chemically broken hair bonds — it fills and smooths cuticle, it does not rebuild internal disulfide bonds.

Overuse threshold: Using it after every single wash on already-healthy, low-damage hair with no break in between can tip fine or low-porosity hair into chronic protein overload (persistent stiffness, increased snapping) — if that happens, stop for 1-2 washes and use a moisture-only conditioner instead.

Usage math: At roughly 2-4ml per use (medium-length hair) out of an 80ml bottle, that's approximately 20-30 applications per container.

Lifespan: Used once per wash at a normal wash frequency, an 80ml bottle lasts roughly 1-2 months for most people; using it at 2-3x the recommended amount per application will burn through it in under 3 weeks without improving results, since correct dosing already covers the hair surface effectively.

Reorder timing: Consider reordering when you notice the bottle is roughly a quarter full, to allow shipping time before it runs out.

If damaged, colour-treated, or heat-styled hair is the starting point, this ampoule's role is the last leave-in step before styling — it doesn't replace shampoo or conditioner, it finishes what they started.

AM/PM routine: 1. Shampoo (see Sec 15 for a protein-lane pick). 2. Rinse-out conditioner (see Sec 15). 3. Towel-dry to damp. 4. CP-1 Keratin Concentrate Ampoule, 2-4ml on mid-lengths and ends. 5. Style or air-dry. No wait time is required between steps 4 and 5.

If you're in the ocean or a chlorinated pool regularly, apply this ampoule immediately after your next hair wash — salt and chlorine both roughen cuticle, and this is exactly the damage profile it's built to smooth over.

If your hair already feels stiff or protein-saturated, skip this product for 1-2 washes and use a pure moisture conditioner instead before reintroducing it.

If you colour-treat your hair, expect faster cuticle roughening between salon visits — this is a reasonable product to use on every wash in the weeks after colouring, tapering off as hair recovers.

Stock-true bundle — Protein Repair Trio (all verified in stock 2026-09-15): CP-1 Keratin Concentrate Ampoule 80ml + CP-1 Bright Complex Protein Shampoo + CP-1 Ginger Purifying Conditioner 500ml. Wash-day protein lane, ampoule applied as the leave-in finishing step.

Stock-true bundle — Scalp Refresh + Ends Repair (all verified in stock 2026-09-15): CP-1 Head Spa Cool Mint Shampoo + CP-1 Ginger Purifying Conditioner + CP-1 Keratin Concentrate Ampoule. For an oily, congested scalp paired with damaged, dry-feeling ends — cool mint shampoo handles the scalp, the ampoule handles the ends.

After purchasing, you will receive our skincare education email series covering this product in depth.

The recommendations above are based on formulation synergy with CP-1 Keratin Concentrate Ampoule, not on margin or stock levels. If a pairing does not exist in our catalog, we say so. If you already own a product that fills the same role, use what you have first.

Primary alternative, verified in stock 2026-09-15: CP-1 3Seconds Hair Fill-Up Ampoule 170ml. Unlike this Keratin Concentrate Ampoule, the 3Seconds Fill-Up is primarily a rinse-off treatment (apply, wait as little as 3 seconds or up to 5-10 minutes mixed with water, then rinse out) rather than a leave-in — if you prefer a treatment that doesn't stay in your hair between washes, that's the trade-off.

Three further verified-in-stock alternatives with different mechanisms: COSRX PEPTIDE-132 Ultra Perfect Hair Bonding Oil Serum (peptide-and-silicone bonding oil rather than a protein-water ampoule — different chemistry, similar damaged-hair use case), d'Alba Professional Repairing Hair Perfume Serum (oil-serum format with a fragrance focus), and FINO Premium Touch Penetrating Essence Hair Oil (a silicone-and-squalane leave-in oil, better suited to sealing/shine than protein-filling).

Thesis: Choose the CP-1 Keratin Concentrate Ampoule over the CP-1 3Seconds Hair Fill-Up Ampoule if you want a no-rinse, wash-day-optional leave-in rather than another rinse-off step added to your shower routine.

IF/THEN upgrade triggers: IF you want a treatment you don't have to remember to rinse out, THEN this leave-in format fits better. IF you specifically want a longer-contact-time intensive treatment night, THEN the 3Seconds Fill-Up's extended rinse-off mode may suit you better. IF your hair already feels protein-saturated, THEN neither product is the right next step — see the Protein-Moisture Balance note in Section 20 first.

Timing and lane: This product is AM- or PM-flexible, applied after any wash, and doesn't conflict with a rinse-off treatment used on a different wash day — they can coexist in a routine rather than compete.

Don't switch if: You already have a rinse-off protein treatment routine you're happy with — adding this on top of it the same wash is redundant, not additive. You have fine, low-porosity hair already showing signs of protein overload. You specifically need a formula without added fragrance (this one is fragranced; check Section 24 before switching from a fragrance-free alternative for that reason).

If you match the convenience and application-flexibility triggers above, this leave-in format is worth choosing. If you specifically want a dedicated treatment night with longer contact time, the rinse-off alternative may suit you better. Consistency beats complexity.

This product's PRIMARY function is: leave-in protein/cuticle-smoothing treatment for damaged hair. You do NOT need this if you already own an unfinished leave-in protein treatment (from CP-1 or another brand) doing the same job — finish your current product before purchasing.

Check your shelf for any open leave-in protein serum or "keratin" treatment before buying a second one; unlike skin actives, there's no PAO-driven urgency to use this quickly, but an unopened backup bottle sitting for many months while an identical opened one is finished is still wasted shelf space.

Stacking assessment: No Benefit if stacked with another leave-in protein product the same wash (same mechanism, redundant). Significant Benefit when paired with a moisture-forward conditioner (different pathway — moisture vs. protein) rather than another protein product.

Quick checks specific to this product: confirm the batch code printed on the box matches the one on the ampoule bottle itself, and confirm the cap seal is intact and unbroken on arrival — we have not identified any documented counterfeit incidents for CP-1 specifically, but these are good general habits for any imported K-beauty product.

Brand Name: CP-1, by parent company Esthetic House Co., Ltd. (South Korea), founded 1996. Headquarters: South Korea. Hero Product: No single hero ingredient — CP-1 is a haircare-only portfolio brand with sub-lines built around different complexes (Aquaxyl moisture, Bright Complex protein, ginger scalp care, and this Keratin Concentrate leave-in line). Manufacturing: Not publicly confirmed whether in-house or via contract manufacturer.

Esthetic House began in 1996 doing cosmetic formulation and development work for other, mostly European, cosmetic brands, before rebranding as Esthetic House in 2010 and launching the CP-1 haircare line in 2014. The brand positions itself as "professional/salon-inspired" haircare, focused on protein and moisture repair for damaged, colour-treated, and heat-styled hair — a positioning this Keratin Concentrate Ampoule fits directly, as a standalone protein-leave-in extension of that same repair focus.

Community reviews for this specific product are limited in what we could independently verify. An Amazon.de listing for this exact product shows a 5.0 out of 5 star rating, but from a single review — too small a sample to draw any real conclusion from.

Multiple K-beauty retailer product pages (repeated near-identically across several independent sites) describe smoother, less-frizzy hair "after the first use" — this pattern of near-identical wording across retailers reads as shared brand/distributor marketing copy rather than independent customer testimony, so we're flagging it as such rather than presenting it as a review.

Direct access to Reddit, YesStyle, hwahae, and Olive Young Global review pages for this exact product was blocked by network restrictions during this research session, so we were not able to independently read and paraphrase verbatim customer reviews. Rather than fabricate plausible-sounding quotes, we're stating plainly: genuine, independently-sourced reviews for this specific product were not available to us at the time of writing.

Sustainability: Check local recycling guidance for the bottle material; no refill program for this product was found in our research.

Can I use this on my scalp? No — every usage instruction we found for this product specifies lengths and ends only, avoiding the scalp and roots.

Is this a leave-in or a rinse-out treatment? Leave-in. Apply to damp or dry hair after washing and do not rinse it out.

Can I mix it into my hair dye? We found a third-party retailer tip suggesting 3-5ml mixed into hair dye to offset colouring damage, but this is not an official brand instruction, so treat it as an unverified anecdotal tip rather than a recommended use.

How often can I use it? No frequency restriction was found — it's designed for use at every wash, though if your hair starts to feel stiff or overloaded, see the Protein-Moisture Balance guidance in Section 20 and scale back.

Does this replace my regular conditioner? No — it's a leave-in finishing step used after conditioner, not a substitute for one; conditioner provides slip and detangling that this protein-forward ampoule isn't formulated to replace.

Hydrolyzed Protein

A protein (like keratin or collagen) broken down into smaller fragments so it can bind more effectively to hair or skin rather than sitting on the surface as a whole molecule.

Keratin

The structural protein that makes up the outer layer of hair; damaged hair has cuticle where this protein structure has been roughened or broken.

Cuticle

The outermost, scale-like layer of the hair shaft; smooth cuticle lies flat and reflects light (shine); damaged cuticle is raised and catches light unevenly (dullness, frizz).

Porosity

How easily hair absorbs and holds moisture and product, determined largely by how open or closed the cuticle is.

Protein-Moisture Balance

The balance between protein treatments (which stiffen/strengthen) and moisture treatments (which soften); too much of either relative to the other causes problems.

Cationic Conditioning Agent

A positively-charged ingredient (like Steartrimonium Chloride) that's attracted to hair's negatively-charged, damaged surface, helping it stick and smooth the cuticle.

Fatty Alcohol

A conditioning, moisturizing type of alcohol (like Myristyl Alcohol) — not the same as drying alcohols like SD alcohol or denatured alcohol.

EU 26 Allergens

A list of 26 fragrance ingredients the EU requires to be individually named on labels when present above a certain concentration, because they're known contact allergens for some people.

PAO (Period After Opening)

The jar-shaped symbol on cosmetic packaging showing how many months a product remains safe/effective to use after first opening.

Store Policies: For the most up-to-date information, please review our Shipping Policy and Refund Policy.

Best for: Anyone with dry, damaged, colour-treated, or regularly heat-styled hair who wants a no-rinse leave-in step to smooth cuticle and cut down on frizz in Mauritius humidity, without adding a rinse-off step to their shower routine.

Key benefits: Genuinely no-rinse and low-effort; avoids-scalp formulation keeps it usable on oily scalps; light, water-thin texture that doesn't feel heavy in humid weather; fits into an existing CP-1 protein-lane routine (shampoo, conditioner, this ampoule).

Keep in mind: It's fragranced with three declared EU allergens, not fragrance-free; its exact protein concentrations aren't publicly disclosed; and fine or low-porosity hair should start with a smaller amount to avoid protein overload.
