I have hair loss form anorexia or extreme dieting for 30 plus years stated age 15, now 56 severe dieting. I have added more protein and hair vitamins, collagen , keratin, coconut oil pills. Rogaines says genetic hair loss but what about nutritional? The supplements have helped thicken strands for sure, would rogaine stimulate dead follicles to grow again, Even if I added alot more calories or have they been dead to long? How about castor oil?
