Hello Doctor, I am having seborrheic Dermatitis since 8 years. I have not treated it for 5 years. Before it was only on my scalp and now it has spread to face (shaving area, ear (back side), chest and back side. I got it treated with a specialist, tried every shampoo, medicines etc. It was less when treated But after that no result. So I said NO to antibiotics. I google for natural cures. Now, I am applying Apple Cider Vinegar 1: 1 (water). Will it work? How to apply the solution? I even have Baking Soda. Can I apply for Scalp? What are the benefits, side effects of both? Will it work? Will it damage my skin? Suggest me other treatments to get rid. What food to eat, what not to eat. I will be very thankful.
