A sensitive scalp essentially means the skin on your scalp is more easily irritated, just like sensitive skin on your hands and face. In fact, the scalp is the third most common area of the body to experience sensitive skin. If you have a sensitive scalp, you may experience itching, redness or irritation. You may also notice dandruff, as your scalp is more likely to be aggravated by exposure to dandruff irritants. Sensitive skin may also be aggravated by factors like stress and pollution – factors that can make dandruff worse too.
