A rich fortifying mask for dry, thick hair prone to fall from breakage
Kérastase Genesis Masque Reconstituant is a fortifying, creamy hair mask for dry and thick hair that is weakened and prone to falling due to breakage. It nourishes and hydrates the lengths deeply, protects the fibre from daily aggressors and targets the most fragile areas to strengthen them. Ginger root extract helps protect against external stress, and edelweiss native cells bring antioxidant care. Hair is left stronger, easier to comb, smoother and much shinier, with less hair fall from breakage.
How it works
A thick, creamy mask that coats the lengths without weighing thick hair down. Applied to towel-dried hair and left for a few minutes, it melts in and rinses out cleanly, leaving strands soft, supple and detangled.
Who it suits
- Dry, thick hair that feels weak and brittle
- Hair prone to falling due to breakage
- Lengths damaged by brushing, heat or colour
- Anyone following the Genesis routine with the bath and serum
Worth knowing before you buy: This mask is designed for thick hair. For fine hair, the lighter Genesis Fondant Reinforcer conditioner is a better fit. It contains fragrance. Hair fall linked to the root is best addressed with the Genesis serum on the scalp.
How long one jar lasts
Used once or twice a week on medium-length hair, a 200ml jar usually lasts 2 to 3 months.
