I hate having seborrheic dermatitis as a Black woman

Also, I hate that I have to spend so much of my money (especially on anti-dandruff shampoo) with non-Black brands. I have seborrheic dermatitis so I can’t use products with shea butter, coconut oil and olive oil. Most brands created by us use those oils. I hate it here. Can’t even co-wash my hair due to this condition.

Edit: Thanks so much for the suggestions, ladies!
