I tie it up really high (which I like because it leaves it just right for styling in the morning), but it still get's tangled. I tried braiding and nothing.

My hair is a little dry even though I tried several moisturizes with it, cremes, oils, etc. I cowashed for months and I think that doesn't work for me. My hair started falling out badly. Huge clumps would come out when I combed in the shower. I stopped for a few weeks now and I'm getting normal shedding again and I feel the thickness coming back but I'm still very upset with the dryness and the tangling because it forces me to do whole combing or dry untangling with my fingers and my brittle hair is very upset with that.

Please help? Oh BTW, I have 3c/3b hair.
