protective styling is a good idea. ive got this problem as well, though extream, a few years ago, (i was 17 at the time, am now 20) i went through a really tough year and due to the stress i pull my hair out, a strand at the time, and i dont even notice it myself, (is a verrry bad habit!) anyhow, ive done it so much that both sides of the temples an inch above my ear, is very short even now, its just started to grow back, and at the nape of my neck. it will take YEARS for my hair to be even again.
so far i use my rosemary oil mixture as a scalp messager and use it on the really bad spots. maybe you want to look at things that might help with hair growth?

my hair: 3b, high porosity, high density and coarse hair (i think i finally figured that all out)
my hair loves conditioner only styling!
Oils and my own procuts are my hairs best friend
my hair goal length is bra strap length when curly.
