The foam is really rich, and it's so cool how it just sinks right into my hair. It doesn't make my hair greasy at all—actually, it feels so soft that I keep touching it. Works great on wet hair, but even after drying, my hair looks super hydrated and full of moisture. It's also super convenient to carry around, so it's perfect for travel if you want to do a treatment on the go, and you can reapply whenever you need. In winter, I sometimes get static, and I think this would help prevent that too. Love it from ANAZE.
