That does makes sense, before my hair journey my hair was way thicker but I joined because I wanted ways to speed up my hair growth, mind you I don't have a growth problem but I realized it wasn't the speed, it was my frequent trimming, and I have cut down on it and have saw significant growth but I think it does have to grow out. The back it's what looks thin and my sides looks ok, I believe it came from this hair dresser putting relaxer on my previously relaxed hair and when I noticed it broke off in the back on the top I stopped going there, but I'm itching to cut but I don't want to and SO doesn't want me to but I worry about the thickness, but keep telling myself it will come
