After 10 years of research, Kérastase presents a new generation of care, developed to descale, repair and drastically reverse hair damage. Reveals hair in its Première state: visibly healthy, strong and with more shine.
Damaged hair is porous and absorbs 3 times more calcium during washing, contributing to an excess of this mineral, which accumulates in the cuticle and hair cortex, making the hair stiff and brittle.
