Hello, I had my hair transplant last year. So I always had the problem that my scalp was very itchy. I very much tried not to scratch my scalp and it succeeded for about a month. But after a month I noticed that I started to scratch my head again in the night. I also noticed a few times that I had small pimples that bleeded. Could that be grafts that I lost or were they just pimples? How bad is it to scratch your head after one month?
