WHAT CAUSES AN ITCHY SCALP?

The following are just some of the conditions and situations that can result in an itchy scalp:3, 4

A reaction to a haircare product. How thoroughly do you rinse your hair in the shower? Leaving some shampoo on your scalp can irritate it, so if your scalp is dry and flaky as well as itchy, and you take super speedy showers, you might need to slow down a little and make sure you rinse your shampoo out completely. If you have an itchy rash on your scalp, that could indicate an allergy to a haircare product (or to one of its ingredients).

Dandruff. If you spot little flakes of skin on your scalp, in your hair, and/or on your clothes, and your scalp is dry and itchy, you might have dandruff. Learn more about dandruff and hair loss here.

Head lice. An itchy scalp is the most common symptom of head lice. It’s actually the bites of the lice that cause the itching, and the bites may also result in red, irritated scalp skin.5

Plaque psoriasis. This is the most common type of psoriasis,6 and approximately 50% of sufferers will experience a flare-up on the scalp. This can manifest as reddish patches on the scalp, flaking similar to dandruff, silvery-white scale, and a dry, mildly to intensely itchy scalp.

Atopic dermatitis. Atopic dermatitis is a type of eczema which can develop on the scalp. Along with an itchy scalp, symptoms can include scalp redness and scale, and the sensation of the scalp burning.

WHAT’S THE BEST TREATMENT FOR AN ITCHY SCALP?

Unfortunately, there’s no single best treatment for an itchy scalp – instead, your best chance of eliminating that aggravating itch relies on correctly identifying the underlying cause and receiving the appropriate treatment.

For example, if your itchy scalp is the result of a reaction to a haircare product, getting relief could be as simple as taking care to rinse your hair thoroughly in the shower, or discontinuing use of the offending product.7 If your itchy scalp is due to dandruff, you might likewise be able to address your symptoms at home with the help of specialized products, such as our Nioxin Scalp & Dandruff Products.

On the other hand, if your itchy scalp is caused by a condition like atopic dermatitis or plaque psoriasis, you’ll need to follow a specialized treatment plan advised by a qualified medical professional.
