I have been diagnosed with rosacea and was wondering if there is such a thing as rosacea of the
scalp. I have little pimples here and there
on the
scalp and extreme itching. I do not have a greasy scalp, dandruff, or head lice . I need help with the itching. I, too, have tried different shampoos, including those with tea tree oil in them and others for so-called dry, itchy scalp-but it's usually for dandruff users.
