Scalp psoriasis, or SP, is a chronic skin disorder marked by thick and flaky patches on the scalp. It can occur anywhere, but most commonly occurs on top of the scalp or around the ears. A patient with scalp psoriasis will often complain of severe itchiness, thick and profuse dandruff, and occasional bleeding of the skin. Several effective treatments exist for scalp psoriasis, and when used regularly, these will keep the disease under control in most cases.
Topical Corticosteroids
According to MayoClinic.com, topical corticosteroids are the most commonly prescribed group of drugs for SP. They come in many forms, including lotions, gels, creams, ointments, and shampoos. Names of such steroid preparations include hydrocortisone, fluocinolone, betamethasone, and clobetasol. In addition, Capex brand shampoo is a highly effective product that contains corticosteroids.
Calcipotriol
Calcipotriol, also known as calcipotriene, is a vitamin D derivative that is available in cream, ointment, and liquid solution forms. A patient can ask his dermatologist for Dovonex, which is the most common brand name for calcipotriol. When used regularly, calcipotriol has been shown to effectively control SP in eighty percent of patients.
Tazarotene
Tazarotene is a topical retinoid and is chemically similar to vitamin A. It requires a doctor's prescription, and is marketed as Tazorac and Zorac, which come in cream or gel form. This medication is best used by massaging the gel into the affected area of the scalp at bedtime, and then rinsing off the product in the morning.
Anthralin
Anthralin, which is a synthetic tar-like compound, works by improving immune function under the applied skin area. Anthralin is similar to coal tar in chemical structure. It is produced as a topical cream, and is marketed under the names Drithocreme, Dritho-scalp and Psoriatec. As it is a potent chemical, anthralin is generally applied for only thirty minutes each day, after which it needs to be thoroughly rinsed off.
Coal Tar Shampoo
Coal tar shampoo features chemical properties that help reduce the itching and dry flakiness accompanting SP. Most coal tar shampoos are available over the counter. Some common brands are Tegrin, Denorex, and T/Gel. Most dermatologists recommend not using such shampoos more than two times a week.
Phototherapy
Phototherapy, or UVB light therapy, involves exposing the skin of an SP patient to ultraviolet light treatment on a regular basis. Treatments may be done in a physician's office, or at home with a portable phototherapy unit. The key to success with phototherapy is consistency of treatment sessions.
