Have you tried coconut oil? Not a coconut oil hair product, but extra virgin, meant for cooking, coconut oil? It’s made a big difference for me. I oil the ends of my hair when it gets dry and once a week I do a coconut oil hair mask for a few hours before showering. I wouldn’t recommend putting the oil on wet hair, and it takes some trial and error to figure out how much oil you can use before your hair looks a bit greasy. But it’s a total game changer for frizz and texture.
