I’ve tried so many hair oils that just left me greasy. But OUAI? It actually works. My hair is naturally frizzy, but the second I smooth this on – dry or damp – it looks amazing. Smooth, shiny, and somehow still bouncy. No weight, no grease. And the smell? Pure heaven. It’s a beautiful white floral blend of violet, gardenia, ylang ylang, and white musk – elegant, not overpowering. I keep sniffing kailygg · sephora.com
