My dd has long, thick hair. I brush it several times a day.. the knots are ridiculous. I have do deal with her crying and fit throwing because she doesn't want to brush it herself (she's old enough). I've tried detanglers, different conditioners, etc. Help me! She needs it long for cheer or else it would have been cut a looooong time ago! What do you Mommas use to make the hair more managable? Has anyone tried that ASOTV tangle free brush?
