A nourishing daily shampoo for dry, weakened hair prone to breakage
Kérastase Genesis Bain Nutri-Fortifiant is a fortifying shampoo for dry, thick or sensitised hair that is prone to breakage. Part of the Genesis range, it cleanses the scalp gently while its formula with edelweiss native cells and ginger root extract helps strengthen the fibre and help reduce breakage. A touch of salicylic acid keeps the scalp clean and comfortable. Hair feels nourished, softer and fuller-looking wash after wash.
How it works
A rich, creamy shampoo that lathers well and rinses clean, leaving lengths soft rather than stripped. It is the nourishing version of the Genesis shampoo, meant for hair on the dry side; the Hydra-Fortifiant shampoo suits normal to oily roots better.
Who it suits
- Dry, thick or sensitised hair that breaks easily
- Hair weakened by colour, heat styling or brushing
- Anyone starting a Genesis routine to reduce breakage
- Scalps that feel slightly tight after harsher shampoos
Worth knowing before you buy: this is a cosmetic shampoo for breakage-prone hair. The formula contains sulfates (sodium laureth sulfate), silicones and fragrance, so it is not the right pick for a silicone-free or fragrance-free routine.
How long one bottle lasts
Used 3 to 4 times a week with a normal amount per wash, the 250ml bottle lasts around 6 to 8 weeks for medium-length hair.
