If you suspect that a skin condition is causing your scalp sensitivity, you will see a dermatologist. For conditions such as fibromyalgia, you may meet with a rheumatologist. For tension headaches and temporal arteritis, you may have to be referred to a neurologist. It depends on the cause. If you’re unsure which doctor to see, book an appointment with your primary care physician, who may be able to treat your condition or refer you to a specialist.
