I make sure my (long) hair is practically dry first. I tried using as it recommends, I think, from damp, but it seems to create frizz with my hair.
I just divide my hair into sections using clips and it works wonderfully, but it does take approx half an hour, so I can't devote the time to this daily.
I know you can buy round (and metal barrel) brushes, and I suppose you could produce similar effect, but I feel is easier with BBH.
