A strengthening shampoo for hair you want to grow long without breakage

Kérastase Résistance Bain Extentioniste is a fortifying shampoo for hair that is growing out and needs to stay strong from root to tip. The shampoo cleanses the scalp and lengths thoroughly and leaves hair feeling fresh and light. Its Creatine R technology combines creatine, which helps protect the inner bonds of the fibre, ceramides, which help restore the cuticle as hair grows, and taurine, which reinforces the core of the fibre. Over time, hair is less brittle and less prone to breaking.

The texture

A fluid gel that lathers easily into a soft foam and rinses out quickly, leaving hair clean and supple.

Who it suits

  • Anyone growing their hair long
  • Lengths prone to breakage and split ends
  • Weakened hair that snaps when brushed
  • All hair types, including fine hair

Worth knowing before you buy: This shampoo contains sulfates (sodium laureth sulfate) and fragrance. If your scalp is very sensitive, or your lengths are very dry, follow with the matching mask or a conditioner.

How long one bottle lasts

The 500ml salon size gives around 70 to 90 washes for medium-length hair, which is about six months at three washes a week.
