Curlypearl and others, I have been useing the Deva Foam since summer. It remains the best mousse on my list. I do NOT have fine hair at all. I live in Wisconsin, which many of you may know, had record high temps this summer, and now it is cool. I do use it with a gel underneath, Biotera, and that worked really well in the summer. Less well now, as it is getting colder, but I am experimenting. I may need to "seal" my hair like many here do. If your curls are not holding up, I suggest a little gel underneath the foam. I agree it is a great product, my most expensive, but it lasts a long time, and as someone said, it is also expensive to buy a lot of products that dont work.
