I have seborrhoeic dermatitis for the past 3 years. My age is 21. I have lost too much hairs with this. How to cure this disease. Please help me. If I use anti dandruff shampoo, it goes off from my head. If I didn't use shampoo, it returns back. Before that I was using" shikakai" which is pure a natural one. I don't know how it came. When I consulted dermatologist, they just give some tablets and shampoo, and they tell me to use for months. I followed their prescription and I was happy for some days. But later again it came. Any natural remedies are their for this. Or give me some good suggestions please.
