Nothing is worse than an itch that just won’t go away! I know for me, when my scalp gets to itching, I cant help but go to town, but relief is possible one we understand where the itch is coming from. Let’s talk about possible reasons you may be experiencing the itch and what can be done about it:
Dandruff. If your scalp is dry and itchy and you see flakes on your hair or clothing, you may have dandruff.
Reaction to a hair care product. 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.
Scalp psoriasis. About 50% of the people who have plaque psoriasis experience a flare-up on the scalp at some point. On the scalp, you may have reddish patches, dandruff-like flaking, silvery-white scale, and a dry scalp. Scalp psoriasis is often itchy, with the itch ranging from mild to intense.
Atopic dermatitis. If you have a type of eczema known as atopic dermatitis (AD), it can develop on your scalp. When this happens, you can have redness and scale on your scalp. Some people say their scalp burns, and the scalp is often itchy.
Nerve problem. An intensely itchy scalp without signs of a rash or another skin reaction can be a sign of a nerve problem. Your doctor may say you have neuropathy (neu-rop-ah-thie). It’s the medical word for a problem along a nerve due to damage, disease, or an abnormality in the way the nerve works. Diseases that can affect your nerves include shingles and diabetes.
Scarring can damage nerves. If you have hair loss that has caused scars that run deep, the scars may have damaged your nerves. This damage can cause your scalp to itch.
The reason it is important to determine the root of the itch is because when a person scratches an itchy scalp repeatedly or intensely, is enough to remove all your cuticular scale. A cuticular scale is a protective covering on every individual strand of hair. The loss of this covering leaves your hair shaft weak and damaged and hence leaves your hair susceptible to easy breakage and hair loss.
