A smoothing shampoo that keeps thick, frizzy hair disciplined in humid weather
Kérastase Discipline Bain Oléo-Relax Shampoo is a gentle shampoo for dry, unruly and frizz-prone hair that is hard to control. Part of the Discipline Oléo-Relax range, it cleanses while leaving the hair softer and more supple, so it combs more easily and frizz stays down for longer. Its nourishing complex relies on shorea butter, which repairs the fibre and gives a light touch and more resistance to breakage, together with anti-humidity actives that help the hair keep its smoothness even in damp weather. Hair looks more disciplined, with controlled volume and a glossy finish.
The texture
A creamy, slightly pink shampoo that makes a rich lather and rinses well. Hair feels smooth and heavy in a good way, with the signature Kérastase fragrance.
Who it suits
- Thick, dry and frizzy hair
- Rebellious hair that puffs up in humidity
- Hair that tangles and is hard to comb
- Anyone who blow-dries or straightens often
Worth knowing before you buy: this shampoo contains sulfates (sodium laureth sulfate) and silicone (amodimethicone), which some curly-hair routines avoid. On fine hair it can weigh the roots down; the Discipline range works best on thick, coarse hair.
How long one bottle lasts
Washing three times a week with two small doses, the 250ml bottle lasts about two months.
