My scalp has been driving me mad with itch the past couple of weeks and now seems a bit flakey. I've changed shampoo/conditioner several times but hasn't seemed to help much. Never had this problem before but doesn't surprise me as the older I'm getting, the more sensitive my skin appears to be getting. Not nits as my mum has checked for me several times 
Before I throw a lot of money blindly trying different ones has anyone any recommendations?
