This has been a miracle for my seborrheic dermatitis. Within just a few uses the foam has cleared up my flares. No real drying or extra flaking that I have seen. I am using it about once every two days though so that may be why I am not having too many issues. Overall I love this medication.

used to treat my seborrhea dermatitis, however is was effective but it caused my skin to be incredibly dry on the effective area even though i could see it getting better. i switched to a more cream based ketoconazole and it is helping my symptoms and keeping it from being dry as well.
Cleared up the serious flakes on my scalp within two applications. You must use it continually, but the results last for a while. I will continue to use it.

Works like a charm! Noticed drastic differences after just two days. Cleared up problem areas. Wish I had known about this earlier. No side effects observed. Using only occasionally for maintenence --not daily, yet benefits remain.
