Psoriasis is a long-term skin condition that may cause large plaques of red, raised skin, flakes of dry skin, and skin scales. There are several types of psoriasis, including psoriasis vulgaris, guttate psoriasis, inverse psoriasis, and pustular psoriasis. Symptoms vary depending on the type of psoriasis the patient has. Treatment of psoriasis may include creams, lotions, oral medications, injections and infusions of biologics, and light therapy. There is no cure for psoriasis.
Alopecia areata is a condition that causes hair loss on the scalp and sometimes other parts of the body. It is believed to be caused by an abnormality of the immune system that causes the body's immune system to attack the hair follicles. Typically, hair regrows within a year without treatment. Steroid injections, creams, and shampoos may be used during treatment.
