Re: seborrich dermatitis on scale and face
What medications have you tried? I have seborrhea, and have found some medications work better than others.
Nizoral (prescription) or selenium sulfide shampoo helps for the scalp. There is also Loprox shampoo, which is a different anti-fungal and it works decently.
Xolegel or Extina foam helps for the face. The foam can also be used on the scalp (they have the same ingredient as nizoral). I think Xolegel works better, but cosmetically it isn't the greatest. Each of these are prescription medications.
These are the US brand names of the above medications. If in a different country, you can check if they are available there, perhaps under a different brand name.
Hope this info is of some help.
