Psoriasis is a chronic condition which needs to be followed up with a dermatologist. For scalp and facial psoriasis, you could apply a shampoo containing coal tar as maintenance 3 times a week. Apply the shampoo and leave it in contact for 10-15 minutes before rinsing off. You could apply 1% HY Chat Doctor. Do not use for more than 2 weeks at a stretch. Other non-steroidal options include topical calcitriol and tacrolimus. Please discuss with your treating doctor about the same. Hope this helps you. Take care. </s>
