Me too, I had itchy scalp and I lost plenty of hair. Sometimes I just washed my hair carefully and it became itchy in half a day. I thought it might be a fungal problem, I got an OTC fungal spray, spray it to my scalp. Leave for one night, and washed it. It's been several months I never used once again, but I feel less less itchy. don't know if this helps. Or maybe yours is a nerve problem I don't know. Just trying to share.
