It has been said thousands of times, but here is what works:
1. Change diet. Eat foods loaded with sulfur eat more garlic and onions.
2. Exercise at least twice per week. Going for a walk will boost circulation and blow flow to the scalp. It will also produce sweat and scalp sebum. This is essential for hair growth.
3. Try using natural hair care products that don't have chemicals. Try Aubrey or Beauty 4 Ashes.
4.Take supplements. Flax oil. To get you hair growing you need to take the raw form and not the pills. Go to Vitamin Shoppe and purchase the whole bottle. You can add the oil directly to a salad or just take it by the spoonful.
5. Wash your hair at least once every two weeks.
Getting you hair to recover will take work, but it is a lot cheaper than laser, but your hair will be stronger.
I wish you the best.

hair loss happens. You are beautiful. Wear a wig until you get it back, this way you can still wash your hair.
