Overview. 1  You may occasionally experience discomfort in your hair or scalp, which might be accompanied by a burning sensation or a sensation that your skin is tight or dry. 2  Wearing your hair in a tight ponytail, bun, cornrows, or tight braids may cause your scalp to feel tender. You may notice the discomfort when taking your hairstyle out in the evening, after wearing it up all day. Minimize your discomfort by altering your hair styles, to avoid pulling on the same spots on your scalp.
