When your scalp itches, it can be difficult to think about anything else. You may feel that the itch will never stop, but relief is possible. Getting rid of the itch begins with finding out why your scalp itches. Your scalp could also feel dry, flaky, scaly, or have red patches.
Special shampoos for an itchy scalp can help relieve your symptoms, as they have ingredients that target different causes of itching, such as dandruff, psoriasis, or head lice. Finding out what is causing the itch, dry scalp symptoms will help you choose the right shampoo.
“An itchy, dry, and flaky scalp could be telling you that you need to do a better job of rinsing the shampoo from your hair. Leaving some shampoo on your scalp can irritate it. If you have an itchy scalp and a rash, you may have a condition called allergic contact dermatitis. This is common among people who dye their hair. Often the culprit is an ingredient in the dye called para-phenylenediamine (PPD), which is found in black hair dyes. You could also have an allergy to a shampoo, conditioner, or other product that touches your scalp. If that’s the case, you’ll likely have an itchy rash on your scalp and any other skin that the product touches,” suggests an article published by the American Academy of Dermatology on its website.
