I'm a guy that wants to grow my hair long. My hair is black and straight, and the length is currently up to the end of my neck. I use a pretty hot temperature to shower. I sometimes use shampoo, but another guy told me that might be part of the problem. When I don't use shampoo it sometimes make my hair feel full of gunk and stickyness...
When I comb it out after a shower, some hairs (around 3-4) fall out.
What should I do?
