What are some causes of itchy scalp?
If it is just itchy scalp without other symptoms, it maybe a result of nervous system disorder caused by stress. It may also be a tic disorder. In this case, the best course of action is to drink herbs and vitamins B1 and B6. If problems persist, talk to a neurologist.
If the condition is accompanied by pimples, sores, head skin peeling and other kinds of skin irritation, then it's a sign that something is wrong. In this instance, you should consult a dermatologist and get checked for psoriasis or eczema.
