Hi Thank you for asking HCM I have gone through your query.Scalp psoriasis is a separate condition from skin psoriasis although there are similarities.It is not must to get a skin psoriasis in those who having scalp psoriasis.First thing you should do is avoid stress as this condition can be worsened by stress.Continue your treatment regularly.Propysalic NF is effective in so many patients.This is a chronic condition but you can get remission by proper therapy.Once you get remission also you should continue coal tar shampoos and ketoconazole shampoo atleast twice weekly.Hope this may help you. Let me know if you have any further queries.
