I stopped using a brush a while ago. It was making my hair a frizzy mess, instead of actually doing what I wanted a good brushing to do :) I switched to wide tooth comb only, but only dry hair, since I'd been told wet hair was so fragile.
Then, last month, I started using my comb in the shower, but only when my hair was full of conditioner. I would still comb my hair after it dried, because I couldn't Scrunch Out The Crunch (SOTC) enough, and it made my hair look wet or producty. (Some women can carry that look off. I am not one of them.)
A few days ago, I switched to only finger combing my hair in the shower (with lots of conditioner). I SOTC when it's dry, and maybe finger ruffle and/or finger comb to break the clumps and get more volume. So, this is my third(?) day with no comb and no brush. I think it's working great, but I don't think it would work unless your hair is super fine and super thin like mine.
But I could be wrong :)
