amika Smooth Over Frizz-Fighting Treatment is a 60-second, rinse-out anti-frizz treatment used after shampoo and conditioner to smooth the cuticle and keep humidity from puffing hair back up. In amika's clinical testing after one use, it instantly reduced frizz by 73% and left hair 2.2 times smoother, with results lasting up to 72 hours, even in high humidity.
The key ingredient is glycolic acid, which amika says helps form a barrier that seals and smooths the hair cuticle, working like an umbrella against frizz. Water lily extract helps tame frizz and improve manageability, and sea buckthorn, amika's signature ingredient, brings vitamins C and A, omega-7 fatty acids and antioxidants. Time-released humidity protection is what keeps the smoothing going for days rather than hours.
It suits every hair type from straight to tightly coiled (1 to 4c), and the 200 ml (6.7 fl oz) bottle has a pointed nozzle so the treatment can be squeezed straight onto wet hair in the shower.
- Rinse-out treatment: leave on 1 minute, then rinse
- Heat styling afterwards gives the best result
- Vegan, cruelty-free and colour-safe; made without sulfates, parabens or mineral oil
