Kerastase Specifique Masque Rehydratant (For Sensitized and Dehydrated Lengths) 200ml/6.8oz

This 200 ml professional moisturizing mask delivers concentrated hydration to dry, stress-exposed hair lengths while reinforcing internal moisture retention between washes.

Hydration Architecture for Dehydrated Fibers

Kérastase Spécifique Masque Rehydratant is engineered for sensitize d lengths that have lost elasticity from environmental exposure, mechanical friction, or prolonged conditioning gaps. The emulsion integrates moisture-binding polymers that draw water into the cortex rather than merely coating the cuticle. This mechanism restores pliability and reduces surface roughness, which is the primary visual indicator of dehydration in both natural and chemically treated hair.

Application Protocol

After shampooing, gently towel-dry strands to remove excess runoff before applying the mask to the mid-lengths and ends. Allow the formula to remain in contact for three to five minutes, then rinse thoroughly with lukewarm water. Because the texture is dense yet highly spreadable, a controlled hand measurement prevents waste: roughly one tablespoon suffices for collarbone-length hair, while shoulder-to-waist locks require approximately two tablespoons per treatment cycle.

Professional Container Specifications

Supplied in a 200 ml / 6.8 fl oz reservoir, this variant supports consistent at-home rotation without relying on dispensers that alter dosage accuracy. Keep the bottle sealed upright between uses to maintain emulsion stability, and store away from direct sunlight to protect the hydrating compounds from UV degradation. Each full application removes approximately six to eight percent of the total volume, delivering reliable performance across twelve to sixteen washes depending on strand thickness.
