I had a whitehead on the 12th day post FUE which ruptured on its own accord.To disinfect the area, I applied some antiseptic liquid to the scalp, leaving for about 30 seconds or so before washing my hair with shampoo. I thought this was a good idea but I then read that you were supposed to dilute the antiseptic liquid before applying. I am paranoid now that I have destroyed the hair grafts. I can't find anything on the internet about this so was hoping somebody here would have some idea.
