A reconstructing mask that repairs brittle, split hair from the inside
Kérastase Résistance Masque Force Architecte is a reconstructing mask for damaged, brittle and dull hair, especially thick hair that feels rough and has split ends. Its Vita-Ciment complex combines pro-keratin, which mimics the role of keratin to rebuild the fiber from within, and ceramides, which act like a cement between the cells of the hair to strengthen it. Resurrection plant sap (Myrothamnus) adds a strong repairing boost. Hair is left deeply softened and nourished, smoother, shinier and easier to comb, with fewer split ends and more movement.
The texture
A rich, creamy mask that coats the lengths well and rinses out cleanly. Hair feels supple and silky afterwards, with the classic Kérastase salon fragrance. A little goes a long way on thick hair.
Who it suits
- Damaged hair that is rough to the touch
- Brittle hair with split ends
- Thick hair weakened by coloring, bleaching or heat
- Dull, lifeless hair that needs more shine and softness
Worth knowing before you buy: The mask contains silicones (amodimethicone) and fragrance. For fine hair, apply only to the ends so it does not weigh the hair down.
How long one jar lasts
Used once or twice a week on medium to long hair, the 200ml jar lasts about two months.
