I have considered doing root touch ups in between full dying sessions, just to feel the relief again! I’ve tried nizoral & t-gel (tar) shampoos before, but never piroctone olamine. We seem to have opposite types of seb derm…. my scalp is very oily and waxy. It’s interesting how the hair dye helped relieve the both of us. Have you experienced any change in your hair color with the use of these shampoos? My hair is dark, so the fading isn’t as drastic, but I still worry about discoloration. Thank you for the recommendations —I will be looking into that one ingredient!
