<s>[INST] Hi.. GM. I am having head scalp psoriasis @ moderate to severe level. Only in scalp area. It is frequently developing even if I shampoo and clean my hair daily. Itching is also there. Pl suggest me a remedy with medical treatment that has no side affects. Thanks,. mn n [/INST] Hi... Psoriasis can affect skin, scalp, nails and bones. As you are having scalp psoriasis moderate to severe variety first try with topical application of solution containing clobetasol and salicylic acid and apply twice daily which will remove scales. Use shampoo which contains coal tar with salicylic acid or containing steroid which also helps in it. To relieve itch take antihistamines tabs. With this if you don't find any improvement then you have to take methotrexate tabs in pulse doses start with 7.5mgper week but after thorough investigations done. If you still don't find improvement contact me further. </s>
