God Bless the person who has made this creation. I’ve used it twice never with a head full of hair because I don’t think that’s what its good for I could be wrong but I use it a couple weeks after a cut to keep fresh. I’m sure it’s going to cut down the amount of times I go to the barber since i live in LA and a haircut is $30 bare min. This brush takes me from bummy to presentable in less than an hour. If you don’t have the time or funds to hit the shop this will get you right for most occasions hopefully you know how to line yourself up though because with out a line up this will only make half a difference. The cutbrush will makes your waves POP! definitely better than any budget clippers I’ve ever purchased. Overall I love it the best/ most useful $65 I’ve spent in a while!
