Has anyone had this? Suddenly last week my scalp became really itchy but it's also affecting the back of my neck and where my neck meets my shoulders. There's nothing to see although I can't really see the affected areas very well.
I've never had dandruff or anything - I bought some Nizorelle shampoo in case that would help but it's not making any difference.
Also tried some anti-histimines today but still nothing helping. No new shampoo, no new soap, nothing to explain it.
any thoughts?
