What if the problem is really, really persistent? MEDIceuticals X-Folate - Persistent Dandruff/Psoriasis Treatment Shampoo is the one to try. A recent customer review:
Psoriasis and Dandruff be gone! I had pretty bad psoriasis and dandruff. Flakes on my shirt, scalp was red and scabby. I used this product 2 or 3 times and my scalp cleared right up. It doesn't smell great, but it's kind of like gasoline: you learn to secretly like the scent. I just follow up with a scented conditioner and I don't have any problems with my scalp. Would Recommend!
