DD, 14, has had a very sore area along her middle parting for a few months. It is red, bumpy to touch (possibly slight scabs/flakes) and flaky, also itchy. I feel like we have tried everything - head and shoulders shampoo, Nizoral, tea tree, oils, hydrocortisone cream, but nothing helps. As it is where her hair is parted it is noticeable. I'd take her to the GP if it didn't take so long to get a non-urgent appointment! Any ideas?
