[Skin Concerns] Treatment for scalp seb derm that won't fade hair color?

Beauty Tips For Body Care
I have seborrheic dermatitis in several places, but it's worst (and itchiest) on my scalp. I've used Neutrogena T-Gel in the past as well as prescription ketoconazole shampoo. They're both mildly effective, but not super great.Here's my other problem: my hair is dyed dark purple, and both these treatments cause significant fading. When I asked my dermatologist about this side effect, she said I was the first person to ever mention it to her.Does anyone else suffer from seborrheic dermatitis and also have brightly-colored hair? Are there any treatments that don't decrease the life of your color?
