Your scalp is an extension of your skin, and should be treated in a similar manner. So, when you're dealing with an itchy, dry scalp, you'll want to use a gentle dry scalp shampoo to help cleanse away flakes without stripping your hair of its natural moisture.
What Causes Dry Scalp?
The most common non-medical cause of a dry scalp is dehydrated skin, according to Dr. Anar Mikailov, M.D., FAAD, a board-certified dermatologist and founder of skincare line KP Away. He says a dry scalp often occurs when you shampoo too often or don't follow up with a conditioner.
Irritation from hair dye, product build-up from dry shampoo, and using harsh ingredients can also cause dry scalp. Eczema and psoriasis can lead to dry scalp, too. Notably, the scaling caused by both skin conditions is a lot thicker than regular dandruff, he adds.
Factors you can't control might also cause dry scalp, according to trichologist Dominic Burg, Ph.D., chief scientist of haircare line évolis Professional. According to Burg, the oil and sebum produced on each hair follicle are generally caused by genetics or hormone levels over your lifetime, including puberty, pregnancy, menopause, and your menstrual cycle.
How Do I Treat Dry Scalp?
Mikailov recommends shampooing twice a week so you're not removing your scalp's natural oils. His go-to tip for patients is to massage a little conditioner or a hair mask onto the scalp as a leave-in treatment.
Berg notes you can safely wash your hair without washing your scalp. “If you have a super dry scalp that is exacerbated by shampooing, then concentrate on the mid-lengths and ends, and don’t shampoo the scalp unless you really need to,” he advises.
Another expert-recommended tip is to read the ingredient label of any prospective dry scalp shampoo. Here are the best and worst ingredients for treating dry scalp, according to Mikailov, Berg, and Dr. Iris Rubin, M.D., a board-certified dermatologist and founder of haircare line SEEN.
