My absolute favorite dry shampoo is the Big Sexy Hair one. It’s pretty expensive so I usually opt for TRESemme but any of them are great! I use the spray dry shampoos to touch up or give my roots volume but when I need a true dry shampoo I use the Ouai Dry Shampoo Foam. It’s a foam and you put it on as if you were putting in a root texturizing foam. It will make your hair damp at first and you just continue to rub it in and then brush it dry. I typically will let it sit on my roots for a bit before I brush. This product is unique in the fact that it actually cleans your hair! Oh, and it smells heavenly!
