Vitamins are the first step in fighting against hair loss. A thorough blood work-up could tell you what you might be lacking OR you can just start out on a multi-vitamin and see how it goes. There’s also vitamins and supplement blends specifically for hair loss.
Here is a list of ingredients that are reported to help prevent hair loss and/or encourage hair growth:
Vitamin B-3: Niacin
Vitamin B-9: Folic Acid
Be careful of Vitamin A – it could cause hair loss! And it is recommended to discuss anything you put in or on your body with your doctor!
