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


Shampoos have harsh detergents that strip oils out of skin in the scalp. This is on purpose, to then sell dandruff and itch remedies. You likely were allergic to your shampoo at home.
Scalp skin oils keep the scalp healthy. Avoid shampoo.
Johnny Harris did a deep dive on the scam of shampoo.
I get where you’re coming from, but I still using the same shampoo, just washing twice, and it’s been great.
I tried the avoiding detergents and washing hair stuff, but it didn’t work.
I just looked like a swamp cresture coming out of a lagoon.
I even shaved my head so I could just use a wet wash cloth. I still got dandruff.
Turns out my own skin is sensitive to hair oil, and I have to wash it every single day very thoroughly or I will get flakes and itchy dandruff.
