Turns out washing your head with shampoo twice and blow drying afterwards fixes my itchy scalp. Don’t ask me why, I don’t know. I just know that since my hairdresser did that, I feel so much better.
Thought I’d spread the word, because it is so frustratingly simple :D
yeah, washing it more than 1x or 2x a week makes it first dry, then oily, itchy and less hygienic overall. don’t over-wash.
