KÉRASTASE Rehydratant Hair Mask for Sensitive Dry Hair — 6.8 fl oz, Lightweight Ceramides & Amino Acids Hydration

KÉRASTASE Specifique Rehydratant Hair Mask is a lightweight treatment that rebalances moisture between oily roots and dry lengths to leave hair softer, shinier, and easier to detangle.

If your scalp tends toward oil while the mid-lengths and ends feel dry, this mask targets that mismatch by delivering hydration where hair needs it without weighing the roots down. Formulated with amino acids, ceramides and vitamin B6, the gel-cream texture absorbs quickly to restore fiber quality and help reduce breakage from tangling. The product is salon-formulated and tested under dermatological control for safety when used as directed.

How does the mask rebalance oily roots and dry ends?

The formula focuses on the hair shaft rather than the scalp, conditioning mid-lengths and ends with a lightweight gel-cream that won’t add excess oil at the roots. Ceramides help reinforce the cuticle while amino acids support the hair fiber, restoring a smoother surface that better retains moisture.

• Targets lengths and ends to avoid buildup at the scalp
• Ceramides reinforce cuticle structure for improved resilience
• Amino acids nourish the fiber to reduce friction and breakage
• Gel texture disperses evenly for light, non-greasy hydration

What results can I expect after using it?

With regular use, hair appears softer, shinier, and easier to manage. Many users notice improved detangling and less tension when combing wet hair, which helps prevent damage from pulling and brushing.

• Softer, smoother lengths with enhanced shine
• Easier detangling to reduce mechanical breakage
• Lightweight finish that preserves volume at the roots
• Improved overall hair quality and manageability

How should I use the mask for best results?

Apply to clean, towel-dried hair, focusing on the mid-lengths and ends—avoid applying directly to the scalp. Massage through, leave on as directed by your stylist or the packaging, then rinse thoroughly; repeat if you follow a double-cleansing routine.

• Use after Bain Divalent or another suitable shampoo for best balance
• Massage through lengths; leave on according to instructions
• Rinse fully and follow styling as usual
• Pair with Potentialiste Serum for scalp and fiber revitalization

Is this safe for sensitized or color-treated hair?

The mask is formulated for sensitive, dry hair and has been dermatologically tested for safety when used as directed; it is designed to be gentle while improving fiber condition. Always patch-test new products and consult with your stylist if you have specific scalp concerns or recent chemical services.

• Dermatologically tested for safety on sensitive hair types
• Gentle gel-cream texture suitable for treated hair lengths
• Helps support hair fiber without heavy silicones
• Avoid direct scalp application if you prefer targeted root treatments

Who is this for: KÉRASTASE Specifique Rehydratant Hair Mask is ideal for people with combination hair—oily roots and thirsty lengths—or anyone seeking a salon-grade, lightweight mask to restore hydration without compromising volume at the scalp. It suits those looking to improve detangling, reduce breakage from mechanical stress, and maintain shine in mid-lengths and ends. Use it as part of a Specifique regimen (for example with Bain Divalent and Potentialiste) when you want a balanced approach to scalp and fiber care.
