Thanks for using healthcaremagic.I understand your concern. 1) You can apply fluocinonide generic solution 0.05% over the affected area in small amount,twice a day,maximum up to two weeks. 2) You can use clobetasol propionate shampoo 0.05% once daily or clobetasol scalp solution(Cormax)0.05% apply over the affected area in small amount,twice daily,maximum up to two weeks. 3)You can use topical calcipotriene solution or foam 0.005%(though little expensive)are also equally effective in treating scalp psoriasis. I would advise you to discuss this with your doctor preferably a dermatologist to consider any of the above prescription if it is appropriate for you.Hope this information helps you.If any further questions, happy to help you.Take care.
