In seeking guidance to unravel the fine hair that I heard about the wood. Well actually it works !! My hair was still matted, even brushing three times a day, I found myself with knots in shambles, even making a mat to sleep, even with shampoos and conditioners after spray ... And since I have this brush, the change is visible! They well unravel, tangle and especially much less, really much less. I can even sleep on occasion with the hair down (not brushed before bed) and still the "recover" the next day without spending hours. And besides I did not think too much to the effect of "brightness" of the other reviews, but the hair is actually much brighter! I will not use anything else ever again, I really recommend it.
