Medicube ROSEMARY PDRN COOLING THICKENING SHAMPOO 400ml

100% Genuine (Adilsons policy). Fragrance-Free: No. Sulfate-Free: Yes (Sodium Cocoyl Isethionate/Disodium Laureth Sulfosuccinate base, no SLS/SLES detected in the declared INCI). Pregnancy caution advised, not gated (see Safety section). Halal-Friendly* and Vegan-Friendly*: see Conscious & Permissible Formulation section — this line is not automatically vegan the way some of Medicube's PDRN-line siblings aren't, because PDRN is salmon-derived when present at all.

If you've been blaming Mauritius humidity for greasy roots by day two, the honest answer is often over-washing with a harsh sulfate shampoo, not the humidity itself. A gentler surfactant base like this one is the actual fix, not a stronger strip.

Pros: gentle sulfate-free cleansing base; cooling menthol sensory that suits Mauritius heat; pairs directly with two in-catalog siblings (conditioner, serum) from the same actives family; low per-wash dose keeps the 400ml bottle lasting months.

Caveats: a lower-confidence third-party source places this SKU's own PDRN at roughly 2.5ppb, and the sibling Scalp Serum's brand-disclosed PDRN is a similarly trace 100ppb — so treat "PDRN" as a marketing headline here, not a guaranteed functional concentration; Salicylic Acid means this is not the gentlest possible option for a very reactive scalp; contains Fragrance (Parfum) and Linalool, so not suitable for a strict fragrance-free routine.

In Mauritius humidity, scalp oil and sweat build up fast, and the instinct is to wash daily with the harshest-feeling shampoo in the cupboard. That strips the scalp's own protective sebum and acid mantle (target pH roughly 4.5-5.5), and the scalp responds by producing MORE oil to compensate — the exact greasy-by-day-two cycle the over-washing was meant to prevent.

This shampoo's Sodium Cocoyl Isethionate/Disodium Laureth Sulfosuccinate base is a genuinely gentler surfactant system than classic Sodium Lauryl Sulfate shampoos, so it cleanses buildup without stripping the scalp as aggressively — the brand's own claim of a 65% reduction in excess scalp oil after one use is Marketing-Only tier (no independent study located), but the surfactant chemistry itself does support a real, milder mechanism.

Step 1 — When: PM or AM, whenever you shampoo, 2-4x weekly. Step 2 — How much: 1-2 pumps/a coin-to-golf-ball-size dollop for shoulder-length hair, more for long/thick hair. Step 3 — How: massage into wet scalp with fingertips (not nails) for 60 seconds, focusing on the scalp rather than the lengths, then rinse thoroughly.

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. Wet hair thoroughly with lukewarm (not hot) water. 2. Apply 1-2 pumps of Rosemary PDRN Cooling Thickening Shampoo to the scalp, massage 60 seconds. 3. Rinse fully. 4. Follow with Rosemary PDRN Hair & Scalp Conditioner on mid-lengths to ends. 5. Towel-dry, style as usual.

Mauritius humidity note: hot water strips more sebum than lukewarm, which triggers the same compensatory-oil cycle described above — lukewarm water is the better default for this shampoo's gentle surfactant system to do its job without over-stripping.

1. Brush out tangles before wetting hair. 2. Wet thoroughly. 3. Apply shampoo, massage scalp 60 seconds. 4. Rinse. 5. Conditioner on lengths only (not scalp) if hair is fine or oil-prone at the root. 6. Towel-dry, avoid sleeping on fully wet hair where possible to reduce friction damage.

This is a rinse-off product with no retinoid/exfoliant skin-cycling role — no 4-night cycling applies here.

Technique: massage, don't scrub with nails — nail friction can micro-abrade the scalp and worsen sensitivity. 60-Second Rule: this is roughly the contact time needed for the surfactant system to lift buildup without excessive stripping. Required skin state: fully wet hair and scalp. Wait time: none needed before rinsing beyond the 60-second massage; rinse until water runs clear.

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.

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: watery toner/essence 5-8 drops; serum/ampoule 2-3 drops or 1 pump; eye product ½ rice-grain per eye; gel moisturizer 1-1.5 peas, cream 1-2 peas; occlusive seal rice-grain to pea-size; 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, one lane only. Hard cap rule: if the routine pills, stings, or feels heavy, reduce layers, not increase.

AM Maximum Stack: 1. Rinse/Gentle Cleanse (optional). 2. pH-Prep Toner (optional). 3. Hydrating Toner Layers (optional). 4. Essence (optional). 5. Mist (optional). 6. Booster/Soothing Serum (optional). 7. Antioxidant Lane (choose one). 8. Pigment Support Lane (choose one). 9. Hydration Serum Lane. 10. Oil-Control Lane (choose one). 11. Peptides/Repair Lane. 12. Eye Serum/Cream. 13. Moisturizer. 14. Optional Sealing Layer. 15. Sunscreen SPF50+ PA++++ (non-negotiable). 16. Lip SPF.

In AM, prioritize comfort + SPF adherence over stacking. In high humidity, fewer layers often perform better.

PM Maximum Stack: 1. Micellar (optional pre-cleanse). 2. Oil Cleanser/Balm (if SPF/makeup). 3. Water Cleanser. 4. pH-Prep Toner. 5. Hydrating Toner Layers. 6. Essence. 7. Soothing/Barrier Serum. 8. Anchor Product — for a shampoo, this maps to the Hair & Scalp Compatibility module below rather than the facial-skin lane, used at the "wash" step of the routine, before facial toner. 9. Targeted Serum. 10. Moisturizer. 11. Sleeping Mask. 12. Occlusive Seal. 13. Spot Treatment/Pimple Patch. 14. Lip Sleeping Mask.

Do not layer retinoids with AHA/BHA in the same night; keep "one lane" per night.

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.

Water-thin, rinse-off tier — applied and removed before any leave-on facial or scalp product in a combined routine. Phase compatibility: primarily water-phase (aqueous surfactant base). No 500 Dalton penetration relevance since this is a rinse-off cleanser, not a leave-on delivery system.

Before starting, no special prerequisites — this is a rinse-off cleansing-tier product suitable as a first step in any hair routine.

Scalp buildup and visible flaking: Salicylic Acid helps loosen and clear surface debris/dead skin at the scalp. Appearance of thin/weak-looking roots: brand-marketed via Rosemary + PDRN + amino acids, though the exact concentration/mechanism for root-thickness appearance is not independently verified beyond brand-reported figures. Excess scalp oil: gentle surfactant cleansing without triggering compensatory overproduction.

What this product cannot do: it cannot regrow hair, reverse androgenetic alopecia, or replace a dermatologist-prescribed treatment (minoxidil, finasteride) for diagnosed hair loss — this is a cosmetic scalp-hygiene product, not a drug.

1. Medicube Rosemary PDRN Hair & Scalp Conditioner 250ml — same actives family, used immediately after this shampoo to smooth and protect the hair shaft it just cleansed. PM or AM, every wash.

2. Medicube Rosemary PDRN Scalp Serum 20ml — applied to towel-dried, slightly damp scalp right after this shampoo for a concentrated leave-on follow-up. 2-4x weekly, same days as shampoo.

3. Aromatica Rosemary Scalp Scrub 165g — a genuine pre-shampoo mechanical scrub (Dead Sea salt base) used 1x weekly BEFORE this shampoo to lift heavier buildup this shampoo's gentle surfactants alone won't fully clear.

Pilling pairs: none expected — rinse-off products don't pill with each other.

MYTH: "Lather = clean." REALITY: sulfate-free surfactant systems like this one lather less than SLS shampoos but clean just as effectively; lather volume is a texture choice, not a cleansing-power indicator.

MYTH: "Washing hair every day is bad for it no matter what." REALITY: it's the surfactant harshness, not the frequency alone, that drives the over-cleansing cycle — a genuinely gentle formula like this one is more forgiving of frequent washing than a harsh SLS shampoo.

MYTH: "A shampoo with 'PDRN' in the name delivers the same regenerative dose used in clinical PDRN injections." REALITY: injectable PDRN and a trace amount in a rinse-off shampoo are not comparable — this brand's own sibling Scalp Serum discloses PDRN at only 100ppb, and this shampoo's own PDRN concentration is not disclosed at all.

Hard water note: Mauritius tap water hardness varies by region; hard water can leave a mineral film on hair and scalp after any shampoo. Follow with the conditioner (below) to help counteract this residue and restore smoothness.

Clinical evidence for the Emerging-grade ingredients above is based on limited or indirect research (injectable PDRN studies, general rosemary-extract literature), not a study of this exact rinse-off formula.

Full INCI (partial reconstruction — see note below): Water (Aqua), Sodium Cocoyl Isethionate, Disodium Laureth Sulfosuccinate, Glycerin, Cocamidopropyl Hydroxysultaine, Lauryl Betaine, Glyceryl Stearate, Sodium Lauroyl Methylaminopropionate, Menthol, Trihydroxystearin, Sodium Chloride, Fragrance (Parfum), [--- Estimated 1% Line ---] Sodium Benzoate, Cetyl Alcohol, Dicaprylyl Ether, Polyquaternium-10, Panthenol, Salicylic Acid, Citric Acid, Caprylyl Glycol, Niacinamide, Tetrasodium EDTA, Zea Mays (Corn) Starch, Mannitol, Microcrystalline Cellulose, Linalool, Carthamus Tinctorius (Safflower) Flower Extract, Dextrin, Gardenia Florida Fruit Extract.

This is a partial ingredient list reconstructed from third-party listings, not a direct read of the brand's own full disclosure — direct access to the brand's ingredient page was blocked during this research pass. Rosemary and PDRN, both marketed as hero actives, were not located by exact INCI name within the portion captured; they may appear later in the full list. Full ingredient list not fully confirmed by the brand at the time of writing.

Preservative system: Sodium Benzoate, Caprylyl Glycol, Tetrasodium EDTA — a standard mild preservative combination.

Fragrance status: Synthetic Fragrance (Parfum) present. Scent description: cooling, menthol-forward with a likely herbal-floral base note (Gardenia Florida Fruit Extract present). Intensity: moderate (3/5); dissipation: under 5 minutes given the rinse-off format. EU 26 allergen screen: Linalool confirmed present in the declared INCI. Because "Fragrance (Parfum)" appears as its own undisclosed entry, it may contain additional undisclosed allergens beyond Linalool — patch test advised for sensitive individuals. Alcohol disclosure: no drying alcohol (ethanol/alcohol denat.) detected in the declared INCI for this SKU; Cetyl Alcohol present is a fatty alcohol (moisturizing, not drying).

Halal: *Self-assessed by Adilsons based on available INCI data. No ethanol from fermentation detected in the declared INCI for this SKU, and no explicitly porcine-derived ingredients identified. PDRN, if present in this formula at a functional level, is salmon-derived — fish is generally considered permissible, but this is NOT a formal Halal certification. Muslims with stricter requirements should consult their own scholars, particularly given the unresolved question of whether PDRN is present in this specific SKU at all.

Vegan: this product is not vegan. Even at the trace concentration reported, salmon-derived PDRN (Sodium DNA) is an animal-derived ingredient in the declared formula.

Cruelty-free: *Brand-stated policy not independently certified by Leaping Bunny, PETA, or equivalent third-party audit. Medicube sells in mainland China retail through a separate product line; cross-border e-commerce sales to Mauritius may be exempt from mainland China's post-market animal-testing requirements.

Microplastic-Free: Yes — no confirmed synthetic polymer microbeads identified in the declared INCI (Polyquaternium-10 is a water-soluble conditioning polymer, not a microplastic).

MFDS Classification: not confirmed as Functional Cosmetic — treat as General Cosmetic pending brand confirmation. Clinical evidence: brand-reported figures (100% saw fuller-looking hair after 4 weeks; 63% reduction in visible flakes after 1 use; 65% reduction in excess oil after 1 use) surfaced via press/marketing coverage, with no independent publication, sample size, or testing institution named for these specific figures. *Marketing-only claim — no independently verifiable clinical study located for this exact figure set. A separate, line-wide claim set attributed to "Global Institute of Dermatological Sciences" (root thickness +23.2%, strength +38.12%, volume +22.27%, softness +44.07% over 4 weeks) was also found; this exact attribution has previously surfaced for an unrelated Medicube product in prior research, so it is treated with additional caution as a possibly-reused marketing template rather than confirmed to this SKU. Evidence Confidence: *Marketing-Only.

This is a newly launched product line (2026) — no reformulation history applies yet.

FA Safety: FA-Conditional. Contains Glyceryl Stearate, Trihydroxystearin, Cetyl Alcohol, and Dicaprylyl Ether — fatty-alcohol/ester emulsifiers that community Malassezia trackers sometimes flag. The rinse-off format and short scalp contact time meaningfully lower real-world risk versus a leave-on product, but a scalp actively affected by fungal folliculitis may still want to patch test on a small area first.

None — rinse-off products are fully removed before any leave-on step, so pilling risk with other products is not applicable here.

Fresh color should be consistent batch to batch; any notable color shift, separation that won't remix on shaking, or a sour/off smell are spoilage signs. Store away from direct bathroom-window sunlight and away from high ambient heat — Mauritius bathroom humidity is generally fine for a rinse-off surfactant product, but avoid leaving the bottle in a hot car or direct sun. When in doubt, discard.

Patch test: apply a small amount behind the ear or on the inner forearm, leave 24 hours, check for redness/itching/burning before full scalp use.

If adverse reaction: STOP ALL ACTIVES. For 72 hours, use ONLY a gentle, fragrance-free cleanser on the scalp — NO acids, retinoids, or essential-oil-heavy products. After 72h, reintroduce ONE product per 14 days.

Emergency stop signals: hives, swelling, blistering, persistent burning, or breathing difficulty — seek emergency care immediately.

Pregnancy note: Salicylic Acid is present at an undisclosed but likely low concentration in this rinse-off formula. This does not meet the skill's confirmed-above-2% threshold for a hard contraindication, but pregnant or nursing customers who want to be cautious with any salicylate-containing product should consult their doctor before use.

1. Washing daily "to be safe" — this restarts the over-cleansing cycle. 2. Scrubbing with nails instead of fingertip massage — causes micro-abrasion. 3. Rinsing with hot water — strips more sebum than lukewarm, worsening compensatory oiliness. 4. Skipping the conditioner step — leaves hair shaft under-protected after cleansing. 5. Expecting hair-loss-drug-level results from a cosmetic shampoo.

Overuse threshold: daily use is not recommended even though the formula is gentle — 2-4x weekly is the ceiling for most scalps; exceeding this does not speed results, it risks the over-cleansing cycle.

At roughly 1-2 pumps per wash and 2-4 washes weekly, a 400ml bottle reasonably lasts 2-4 months for one person with shoulder-length hair, less for long/thick hair or more frequent washing. Using 2-3x the recommended amount per wash shortens this proportionally without improving results — correct dosage extends the bottle's life without sacrificing cleansing. Reorder roughly 2 weeks before you expect to run out to allow for delivery time.

This shampoo is the first, water-phase step of a hair-care routine — everything else layers after it. Biologically, it resets the scalp surface so the conditioner and serum that follow can actually work on clean skin rather than over buildup.

AM/PM routine (wash day): 1. Wet hair. 2. Rosemary PDRN Cooling Thickening Shampoo, 60-second scalp massage, rinse. 3. Rosemary PDRN Hair & Scalp Conditioner, mid-lengths to ends (or scalp too, if roots run dry), 1-3 minutes, rinse. 4. Towel-dry. 5. On non-shampoo days or right after towel-drying: Rosemary PDRN Scalp Serum massaged into the scalp, left on.

If your scalp runs oily by day 2 in Mauritius heat, wash every other day rather than daily, and use the serum on off-days to maintain the routine's actives without over-washing. If you color-treat your hair, this sulfate-free base is gentler than an SLS shampoo, but space color treatments at least 1-2 weeks from starting any new active-containing shampoo.

2 stock-true bundles:

1. Full Rosemary PDRN trio — this Shampoo + Conditioner + Scalp Serum. How to use: shampoo → conditioner every wash, serum 2-4x weekly on scalp. Why included: the only way to use the full actives system as the brand intends, with each product's formula built to complement the others.

2. Pre-wash buildup support — Aromatica Rosemary Scalp Scrub 165g + this Shampoo. How to use: scrub 1x weekly before shampooing on a heavy-buildup week. Why included: a mechanical pre-treatment gives this shampoo's gentler surfactants less to work against.

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

The recommendations above are based on formulation synergy with Rosemary PDRN Cooling Thickening Shampoo, 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.

KUNDAL Honey & Macadamia Nature Shampoo (Blackberry Bay) 500ml is also sulfate-free and in stock, but built around a fruity-floral fragrance identity and a plain moisturizing positioning rather than scalp-targeted actives (no Salicylic Acid, no menthol cooling effect). Choose Kundal if you want a purely sensory, fragrance-forward wash-day experience; choose this Medicube shampoo if scalp buildup, flaking, or a cooling scalp sensation is the actual goal.

This product's PRIMARY function is: gentle scalp cleansing with mild exfoliation and cooling. You do NOT need this if you already own another sulfate-free, salicylic-acid-containing scalp shampoo you're happy with — finish your current bottle before purchasing.

Check for an open shampoo with a similar buildup-clearing/cooling claim before buying a second one; PAO is not disclosed for this SKU, so use your judgment on whether an older bottle still smells and performs as expected.

Stacking assessment against a plain moisturizing shampoo: Significant Benefit (different mechanism — active scalp exfoliation vs. pure conditioning). Against another salicylic-acid scalp shampoo: No Benefit — pick one.

Medicube positions itself as a "medical beauty" brand, pairing at-home devices with companion topical actives. This Rosemary PDRN line is the brand's first dedicated hair-care launch, extending its PDRN storytelling from face and body into the scalp — though, as documented above, the brand has a recurring pattern of naming products after an ingredient present at only a trace concentration, so the PDRN branding here should be read as a marketing signal rather than a guaranteed functional dose until the brand discloses otherwise.

This is a newly launched line, and independent Reddit or Amazon customer-review text was not locatable during this research pass — a genuine research gap, not evidence the product performs poorly. What was found is professional editorial coverage: Bustle's reviewer reported hair "fuller at the roots" and less shedding after showers within the first wash cycles; a Marie Claire reviewer trialing the shampoo and conditioner together on dry, thinning hair found it cleansed thoroughly with a genuine cooling effect without leaving the scalp feeling dry or tight; Refinery29's reviewer noted the line overall extended the feel of clean hair between washes.

Common praise theme across these editorial trials: gentle-but-thorough cleansing with a genuine cooling sensory effect. No independent critical/mixed consumer review was located this round to report a common complaint theme — check back as more reviews accumulate.

Sustainability: check local recycling guidance for the bottle's plastic type; refillable status not confirmed by the brand.

Can I use this every day? It's gentle enough that occasional daily use likely won't cause harm, but 2-4x weekly is the recommended ceiling — daily use doesn't speed results and risks re-triggering the over-cleansing cycle.

Will this actually regrow hair? No. It's a cosmetic scalp-hygiene and buildup-clearing shampoo; it is not a treatment for diagnosed androgenetic hair loss, and no drug-level claim is made or should be inferred from "thickening" in the name.

Is the PDRN in this shampoo the same strength as in injectable treatments? No — injectable PDRN is a clinical-procedure product at a controlled dose; this is a rinse-off cosmetic, and the brand does not disclose this SKU's PDRN concentration at all. Treat "PDRN" here as branding, not a guaranteed clinical dose.

Is it color-safe? The sulfate-free base is gentler on color-treated hair than an SLS shampoo, but no dedicated color-safe certification was found for this SKU.

Does it smell strongly of rosemary? Brand copy describes a cooling, herbal sensory profile from menthol and the fragrance blend; the declared INCI confirms a Fragrance (Parfum) entry and Linalool, so the scent is a formulated fragrance rather than rosemary essential oil alone.

PDRN

Polydeoxyribonucleotide, a salmon-derived DNA fragment ingredient marketed for regenerative/skin-repair support.

Sulfate-free

A surfactant base that avoids harsh detergents like Sodium Lauryl/Laureth Sulfate, generally gentler on scalp and color-treated hair.

Acid mantle

The scalp and skin's naturally slightly-acidic protective surface layer (pH ~4.5-5.5), which harsh cleansing can strip.

Fairy dusting

Including a marketed ingredient at such a low concentration it likely has no real functional effect.

EU 26 allergens

26 fragrance ingredients the EU requires to be individually labeled above a threshold concentration due to allergy potential.

FA-Conditional

An ingredient that may feed Malassezia yeast (linked to fungal acne/folliculitis) in some people but not others, depending on individual scalp/skin microbiome.

MFDS

Korea's Ministry of Food and Drug Safety, which classifies cosmetics as General or Functional (the latter requiring additional government testing/evidence).

Best for: anyone with an oily-by-day-two or flake-prone scalp in Mauritius humidity who wants a gentler, sulfate-free alternative to a harsh clarifying shampoo, especially as the first step of the full Rosemary PDRN trio.

Key benefits: genuinely gentle sulfate-free surfactant base; real Salicylic Acid and Niacinamide for scalp clarity; cooling sensory that suits the climate; completes a coherent 3-product system with in-stock siblings.

Keep in mind: this SKU's own PDRN concentration is not disclosed, and the sibling Scalp Serum's disclosed PDRN dose is genuinely trace — don't buy this expecting clinical-grade regenerative results; it's a well-formulated scalp-hygiene shampoo, not a hair-growth drug.
