My hair is very thick---to the point I go get it thinned every 4 weeks. This brush helped with getting a little f the excess water out when drying it. It took about the same about of time to dry maybe a little less. But it helps with the roots!
Sorry I disagree completely with Angel. I have LONG and THICK hair that usually takes 20-25 minutes to dry and not completely. Using this brush I was finished in about 10 minutes. My hair was silky, smooth and shiny.
