Make an appointment in your Kérastase salon for a personalized hair diagnosis. The Nutri-Fortifiant Shampoo gently cleanses the scalp and hair, intensely moisturizes, and easily detangles, strengthening hair weakened by heat damage and brushing. The Hydra-Fortifiant Shampoo gently cleanses the scalp and hair to remove excess buildup, strengthens hair weakened by heat damage and brushing, and nourishes and easily detangles.

The Renforcateur Conditioner intensely moisturizes and adds body, strengthens hair weakened by heat damage and brushing, and easily detangles and prevents split ends. The Reconstituant Hair Mask intensely nourishes and hydrates hair, strengthens hair weakened by heat damage and brushing, and smooths and easily detangles.

The Defense Thermique Hair Serum protects against heat styling, delivers up to 24 hours of frizz protection, and strengthens hair weakened from brushing and over-styling. The Fortifiant Hair Serum strengthens hair weakened by heat and brushing, hydrates hair and adds shine, and has a lightweight, non-greasy finish.

The Masque Reconstituant Hair Mask intensely nourishes, detangles, and reinforces the hair to reduce the risk of hair fall due to breakage from brushing. It restores intense softness for beautiful healthy-looking hair. Apply it to shampooed, towel-dried hair, massage the lengths and ends, leave on for 5 minutes, and rinse thoroughly.

We recommend using the Masque Reconstituant Hair Mask instead of the Fondant Renforcateur Conditioner as often as needed, using it after shampooing (in place of a conditioner) weekly or as needed. The Masque Reconstituant Hair Mask is meant to take care of lengths and ends and does not need to be applied on the scalp.
