Exceptional hair knows no limits. Extend your limits with Kérastase Extentioniste, Kérastase's first hair training program designed to optimise and reinforce the length of damaged hair. Great for those with longer hair or those looking to grow their hair, Extentioniste works to reinforce the internal structure of the hair and seal the cuticle to prevent breakage and split ends for healthy growth.
