The onset of psoriasis is not only on the scalp, but also on the whole body, so psoriasis that attacks only on the scalp is rare. The treatment of psoriasis on the scalp with Kang Wang is not suitable because the composition of Kang Wang is 2% ketoconazole lotion, which is an antifungal lotion, and psoriasis is not directly related to fungal infection. The treatment of scalp psoriasis is the same as the treatment of body psoriasis, the only difference is that the hair will be covered when topical medication is applied, but it is required that it must be rubbed on the scalp to have an effect, the other parts of the body are relatively good to rub, so it is best to cut the hair short, for men it is also possible to cut it bare, the effect of rubbing the medication will reach the best, or use ultraviolet radiation to be able to irradiate in place. Treatment methods for scalp psoriasis include oral, topical, light, etc. Although you can choose to use topical hormones, do not use them for a long time, and do not use them repeatedly and intermittently for a long time; generally speaking, topical hormones can be used for 3-6 weeks, and after controlling the disease, consider non-hormonal topical drugs, such as carboplatin, tacrolimus, etc., or even some hormone-free Chinese medicines or skin care products to control the onset and development of psoriasis.
