Having a dry, itchy scalp is a common problem that has a variety of causes. In most cases, dryness and itching are not signs of a serious condition and can be easily treated. However, sometimes these symptoms are reflective of a more persistent dermatological problem that may need the oversight of a good doctor or may require medication or other forms of treatment.
Seborreheic Dermatitis
Seborreheic dermatitis is commonly known as dandruff in adults and "cradle cap" in babies. It is a skin condition that can appear on the scalp and other parts of the body. On scalps, the condition creates scaly, itchy, red patches with greasy, yellowish flakes. According to MayoClinic.com, the exact cause of seborrheic dermatitis is unknown, but it is generally believed to be brought on by stress, fatigue, certain neurological conditions, a change in season, or a fungus that grows in oil secreted by glands in the skin. Seborrheic dermatitis can be treated with an over-the-counter antifungal cream or by using a special medicated shampoo that contains ingredients such as Ketoconazole, Ciclopirox, tar, pyrithione zinc, selenium sulfide or salicylic acid. To avoid future seborrheic dermatitis outbreaks, be sure not to use any harsh soaps or chemicals on your scalp and to shampoo your hair daily.
Scalp Psoriasis
Psoriasis is an autoimmune condition that causes patches of thick, itchy, red skin. The National Psoriasis Foundation reports that at least half of all people with psoriasis have it on their scalp. Scalp Psoriasis is very similar in appearance to seborrheic dermatitis, but rather than having yellowy flakes, psoriasis is powdery with a silvery sheen. The condition can range from mild, with just a few patches, to severe, where patches cover the entire scalp. In mild cases, shampoos and products containing tar or salicylic acid can help to treat the condition. However, in moderate to severe cases, you may need to apply an antimicrobial ointment to your scalp, take oral medication, or undergo UV light therapy.
Environmental conditions
Certain environmental factors can cause a dry, itchy scalp. Conditions that dry the scalp, such as indoor heating or air-conditioning, can create a itchy scalp. 4-men.org also reports that excessive travel in airplanes can cause the scalp to become dry and itchy given the lack of humidity in the air in most airplanes. When you can, it is best to turn the heat and air-conditioner to as low levels as possible. You may also want to give yourself regular oil treatments by massaging a light oil such as olive or almond oil into your scalp, wrapping a towel around your hair, leaving it for a half hour and then rinsing out the oil with lukewarm water.
Mistreatment of Hair
You may accidently cause dry, itchy scalp by mistreating your hair. Holding your hair dryer too close to the head, excessive shampooing, and using certain hair products can severely reduce the amount of natural oil in the scalp, making your scalp arid and tight-feeling. If you are suffering from a dry, itchy scalp, switch the heat level on your blow-dryer to low, cut back on how often you wash your hair, and avoid hair care products that contain alcohol.
