Itchy Scalp Any Ideas to stop Scratching.

Hi Sister,  I clipped it no 2 all over last weekend as hair was just coming out in balls of fluff on my hairbrush and then last couple days it's come out in chunks look like a half plucked chicken so gross to look at and annoying the heck out of me couldn't sleep. I think it's my beanie, just exposing it just now it has settled down but so cold. Ill try going over it with no 1. Also Is there any particular material to avoid on bald scalp or anything to help sensitive scalp? Thanks for your reply.
