Long & Strong Shampoo is the first step in Keune’s award-winning Long & Strong hair and scalp routine, which won a 2026 Dutch Beauty Award in hair care. It’s made for fragile, thinning, or breakage-prone hair. It gently cleanses without stripping, invigorates the scalp, and releases strengthening ingredients that support both the hair fibre and the scalp.

Clarify and refresh: Salicylic acid helps remove buildup and pollution for a cleaner, healthier-feeling scalp.
Strengthen: Marine Density Infusion (dulse seaweed extract) and biotin help strengthen strands, so hair looks and feels fuller.
Soothe: Centella asiatica calms and protects the scalp with antioxidant care.
Nourish: Panthenol and glycerin add moisture and softness.
Shine: Used with the Long & Strong Conditioner, it gives up to 76% more shine.

Hair feels fuller and denser with a lightweight touch, and becomes stronger and more resilient with regular use. The formula is sulfate-free, silicone-free, vegan, gluten-free, and cruelty-free.

Apply to damp hair and massage into the scalp to build a lather.
Work the lather through the lengths, then rinse thoroughly.
Repeat if needed.
For best results: Follow with Long & Strong Strengthening Conditioner, then Long & Strong Super Serum on the scalp and Densifying Leave-In on the lengths.
For a scalp reset: Pair with Keune Perfect Clarity Exfoliant.

All hair types and textures, especially fine, thin, fragile, or breakage-prone hair, and seasonal or postpartum shedding. It’s ideal for anyone wanting stronger, fuller-looking hair and a healthier-feeling scalp. Safe for colour-treated hair.
