I’ve always used Neutrogena but found it’s not as effective these days and my hair never looks in good condition.
My scalp can not only flake but scab/bleed.
At the moment I’m using a goats milk shampoo brand I bought from a Christmas market (several colleagues had recommended their cream and soap for excema/dry skin so I was buying my mum some of that) and my scalp hasn’t itched or bled at all from it but I have a shower of ugly dandruff every day.
