KÉRASTASE Specifique Rehydratant Hair Mask — 6.8 fl oz | Lightweight hydration for dry lengths with ceramides

KÉRASTASE Specifique Rehydratant is a balancing hair mask that restores lightweight hydration to dry lengths while rebalancing scalp moisture for softer, shinier hair.

This salon-grade treatment targets hair that struggles with dry mid-lengths and ends together with oilier roots. Formulated with ceramides, an amino acid complex and vitamin B6, the mask strengthens fiber, improves detangling and leaves a weightless finish. It belongs to the Specifique line, designed to correct moisture imbalances without weighing hair down, and complements Bain Divalent shampoo and Potentialiste serum for a complete routine.

How does this mask rebalance hydration without making roots greasy?

The formula combines lightweight gel-cream texture with ingredients that fortify hair rather than saturate the scalp. Ceramides reinforce cuticle integrity along lengths while amino acids help attract and retain appropriate moisture levels, so mid-lengths and ends feel nourished while roots stay fresh.

• Ceramides: rebuild the hair surface to lock in moisture where needed
• Amino acid complex: supports hydration control and fiber resilience
• Light gel texture: conditions lengths without coating the scalp
• Use with Bain Divalent for targeted scalp cleansing

What results can I expect after a few uses?

Regular application improves manageability and shine while reducing the tug of tangles. Clinical-style feedback indicates most users notice easier detangling and an overall improvement in hair quality without extra weight or limpness.

• Softer, smoother lengths and ends
• Visible increase in shine and healthy-looking fiber
• Up to 81% reported easier detangling after use
• Reduced breakage from mechanical stress during brushing

How should I use the mask for best performance?

Apply after shampooing on clean, towel-dried hair, focusing on mid-lengths and ends. Massage through, leave on briefly according to your hair porosity, then rinse thoroughly; avoid the scalp if you prefer lighter results. For a balanced regimen, follow the Specifique recommendations and repeat cleansing or treatment as directed.

• Step 1: Shampoo with Bain Divalent for oily roots and dry lengths
• Step 2: Apply mask to towel-dried hair, concentrate on lengths and ends
• Step 3: Massage, leave for suggested time, then rinse completely
• Step 4: Combine with Potentialiste serum for revitalized fiber

Who is this for: KÉRASTASE Specifique Rehydratant suits anyone with combination hair—oily at the roots and dry through the lengths—or sensitive, brittle hair that needs moisture without heaviness. It's appropriate for color-treated or chemically processed hair that requires strengthening and easier detangling. If you want salon-grade hydration that restores balance and leaves hair soft, shiny and manageable, this 6.8 fl oz treatment is formulated to fit into a corrective haircare routine.
