Scalp psoriasis, medically known as psoriasis, can be treated with general treatment, medication and other treatments as prescribed by the doctor. 1. General treatment: daily should avoid triggering or aggravating factors of psoriasis, pay attention to keep scalp clean, avoid labor and mental tension. 2. Drug treatment: topical glucocorticoid drugs such as dexamethasone and halometasone can be used, which have the effects of immunosuppression and anti-inflammation; vitamin D3 derivatives, such as caspofungin, have the effects of inhibiting the proliferation of skin keratinocytes and inducing their differentiation, which can promote the reduction of psoriasis lesions. If the effect of topical application is not good, oral immunosuppressants, such as methotrexate, can also be used. 3. Other treatments: Physical therapy, such as UVB phototherapy and excimer laser, can also be considered, which can slow down the rapid growth of skin cells and inhibit the activation of immune cells. If the patient has anxiety and depression and other psychological, also need to receive psychological treatment. It is recommended that psoriasis patients go to regular hospitals, cooperate with doctors for standardized treatment, and do not blindly use drugs on their own.
