Maybe help the regrowth of the hair with a change in diet. Increase your protein intake. Get both protein and omega-3/6 fatty acids by eating fish, tuna is a good source of both protein and fatty acids, as well as almonds. Add vitamin B and C to your daily multivitamins and 8 glasses of water a day will help prevent additional hair breakage. Vitamin A will help with your scalp health. Don't know if you're in a cold weather climate, but that can't help your situation, as well as caffeine and rapid weight loss will have an adverse effect. This doesn't sound awesome, but avoid washing your hair a couple days (use a shower cap) to let your natural oils help your scalp. The change won't be quick, but hopefully this helps.
