A strengthening shampoo from Kérastase's Résistance line, aimed at damaged and over-processed hair. It pairs keratin and protein with a sulfate-free cleansing base to smooth the cuticle and reduce breakage over time. The pump bottle holds 16.9 fl oz, which lasts longer than most salon-size shampoos. Compared with mass-market repair shampoos, it is a premium step, but regular users say the difference shows on brittle, chemically treated hair.
