All part and parcel of the disease, which I have had in different degrees since a teenage.
Thankfully for me, I only have it on my scalp now, hence no hair, but, in my experiments I found a cheap cream that really works regarding the itching and soreness. Loads of folk sell it on Lazada, but if you keep searching, you can find it for about 20 bht a tube, well worth a try. I buy 5 tubes at a time, you will not find it in the shops...Link below..
