Dry, parched hair doesn't just need moisture — it needs the right combination of antioxidants, vitamins, and emollients to restore the hair's ability to hold and reflect light again. Dull, brittle hair isn't just dehydrated; its structural protein network has been depleted, its cuticle surface has roughened, and its capacity to retain moisture has been compromised. HYDRATE-ME.WASH addresses all three — a sulphate-free, vitamin-rich hydrating wash that replenishes moisture, smooths the cuticle, and restores the healthy glow that parched hair has lost.

HYDRATE-ME.WASH is built around a concentrated blend of antioxidant botanicals and nourishing oils that deliver hydration during the cleanse step — not just after it.

Terminalia Ferdinandiana (Kakadu Plum) Fruit Extract is KEVIN.MURPHY's signature hero ingredient. Native to Australia's Northern Territory, Kakadu Plum has the highest known concentration of natural Vitamin C of any plant on earth — up to 100 times more than an orange. In hair care, this extraordinary antioxidant density serves two functions: it smooths the cuticle surface to lock in essential moisture and restore shine, and it neutralises the free radicals generated by UV exposure, heat styling, and environmental pollution that progressively degrade the hair's structural proteins.

Retinyl Palmitate (Vitamin A) smooths the appearance of the hair shaft and helps increase elasticity — the resilience that allows dry, brittle hair to flex rather than snap. Ascorbic Acid and Ascorbyl Palmitate (Vitamin C) provide additional antioxidant reinforcement alongside the Kakadu Plum extract. Tocopherol and Tocopheryl Acetate (Vitamin E) protect the hair's lipid layer from oxidative degradation. Pyridoxine HCl (Vitamin B6) and Panthenol (Provitamin B5) support the hair's metabolic health and bind moisture structurally within the cortex. Biotin (Vitamin B7) strengthens the hair shaft and contributes to the formula's damage-prevention profile.

Butyrospermum Parkii (Shea) Butter delivers rich emollient moisture from root to tip — absorbing rapidly without clogging the cuticle, rehydrating both hair and scalp while protecting against the environmental stressors (dryness, brittleness, breakage) that compromise dry hair. Oenothera Biennis (Evening Primrose) Oil is exceptionally high in Omega-6 fatty acids and phospholipids — moisture-loving, hydrophilic compounds that are attracted to water and help the hair shaft retain it. Rosa Canina (Rosehip) Fruit Oil provides additional essential fatty acids and Vitamin C. Jojoba Esters add lightweight conditioning and surface smoothing. Undaria Pinnatifida Extract (wakame seaweed) delivers marine minerals and amino acids that reinforce hair strength. Centella Asiatica Extract provides soothing anti-inflammatory properties for the scalp. Arctium Lappa (Burdock) Root Extract strengthens and nourishes at the scalp level. Citrus Aurantium Bergamia (Bergamot) Fruit Extract balances the hair and scalp with its antioxidant-rich botanical profile. Hydrolyzed Milk Protein deposits into micro-fractures to reinforce tensile strength and improve manageability. Amodimethicone and Silicone Quaternium-18 provide conditioning, detangling, and surface smoothing.

The surfactant system — Sodium Cocoyl Isethionate, Disodium Laureth Sulfosuccinate, Cocamide MIPA, Cocamidopropyl Hydroxysultaine — is sulphate-free, producing a rich, creamy lather without the aggressive stripping of SLS or SLES.

When used with HYDRATE-ME.RINSE, internal testing showed 5x more shine and 3x smoother hair after just one use.

Sulphate-free. Paraben-free. Cruelty-free.

Metro Vancouver note: Hard water mineral deposits compound dryness by roughening the cuticle surface and blocking moisture uptake — meaning even a vitamin-rich hydrating shampoo will underperform on hair with active mineral buildup. If results are less than expected, a chelation step before your HYDRATE routine may be the missing variable. See our Hard Water Hair Damage hub for the protocol.

Who It's For Normal to dry or naturally dry hair of any texture. Particularly effective for hair exposed to harsh, dry climates, UV damage, or frequent heat styling. Colour-safe. Can be used daily. Works across all hair types including colour-treated and chemically processed hair.
