OUAI Lightweight Hair Oil for Frizz Control
by OUAI · hair_care
Editor's Take
Sold as an oil, built mostly from silicone; it earns its keep on frizz and shine, but the botanical roll call oversells what leads the bottle.
Four-pillar formula scores
- Performance: 8.2 / 10
- Innovative Ingredients: 6.8 / 10
- Clean Standards: 1.5 / 10
- Formula Sustainability: 1.1 / 10
The Verdict
Marketed as an oil, formulated as a silicone shine treatment. Cyclopentasiloxane and Dimethicone provide strong humidity resistance and surface polish, while sweet almond and jojoba oils play supporting roles. That performance comes with poor clean and sustainability credentials, largely because the dominant silicones are persistent and poorly biodegradable. Worth it for dependable frizz control, though the oil branding gives the botanicals too much credit.
