So I’ll get days where my scalp itches uncontrollably and even if I only scratch it once or twice it will be raw and oozing, the next day it will dry into a scab. Any tips on how to keep the scabs intact or at least clean when showering the next days? I usually use a medicated shampoo and let it sit for as long as possible, but when there’s scabs I try to avoid getting the shampoo on them.
