Seborrheic dermatitis is a common skin disease that causes an itchy rash with flaky scales. It causes redness on light skin and light patches on darker skin. It's also called dandruff, cradle cap, seborrhea, seborrheic eczema, and seborrheic psoriasis. It might look similar to psoriasis, eczema, or an allergic reaction. It usually happens on your scalp, but you can get it anywhere on your body.
If you have seborrheic dermatitis on your scalp, use an over-the-counter dandruff shampoo with one of these ingredients: ketoconazole, ciclopirox, selenium sulfide, zinc pyrithione, coal tar, and salicylic acid, used twice weekly for at least a month and if necessary, indefinitely.
- Zinc Pyrithione: Zinc pyrithione is an antimicrobial that is often listed as the active ingredient in OTC dandruff shampoos. Because zinc has powerful antifungal properties, it's good at killing yeast overgrowth. It may also be available as a cream and is often recommended for daily use.
- Selenium Sulfide: Selenium sulfide is an antifungal that can slow down the overgrowth of yeast on your scalp and skin. Some products contain both selenium sulfide and zinc pyrithione. It can be a little harsher than zinc pyrithione, though, so it's best to start slow by using the product only a couple of times per week at first (then building up from there), keeping an eye out for skin irritation.
- Ketoconazole: This antifungal has more uses than some of the other antifungals on this list, and can be prescribed to treat everything from athlete's foot to tinea versicolor to ringworm. If you do opt for the shampoo, make sure to follow the directions on the packaging; it's usually recommended that you only use it twice per week or every three days on the scalp.
- Salicylic Acid: if your seborrheic dermatitis consists of thick crust or patchy scales, it can help to choose a shampoo with salicylic acid. This beta-hydroxy acid removes the dead cells that build up on the surface of the skin, forming unsightly, stubborn, and itchy patches of scaly or flaky skin.
