OUAI Shampoo for Fine Hair
by OUAI · hair_care
Editor's Take
For fine hair that collapses under richer shampoos, this earns its shelf space with crisp cleansing and light conditioning, but its environmental footprint is hard to excuse.
Four-pillar formula scores
- Performance: 7.8 / 10
- Innovative Ingredients: 6.8 / 10
- Clean Standards: 2.0 / 10
- Formula Sustainability: 2.5 / 10
The Verdict
The formula is well judged for fine hair: Sodium C14-16 Olefin Sulfonate gives a thorough wash, while Panthenol, hydrolyzed keratin, and targeted silicone conditioning limit the straw-like finish. That strong detergent may feel drying on sensitive or already parched scalps, and the scented blend includes several disclosed allergens. It is not a clean-beauty or low-impact choice, given the PEGs, ethoxylates, persistent conditioning polymers, and conventional petrochemical load. A credible volumizing shampoo when performance comes first, with a footprint that looks dated beside greener peers.
