IF YOUR HAIR IS THINNING: 1. Iron (with food): 18 - 25 mg. Delivers oxygen to hair follicles, especially in women. 2. Saw palmetto (daily): 320 mg. Reduces DHT levels that shrink hair follicles. 3. Pumpkin seed oil (daily): 1,000 mg. Increases hair count by blocking hormone-related thinning. 4. Zinc (with food): 15 - 30 mg. Supports protein synthesis needed for hair growth. 5. Vitamin D (daily): 1,000 - 4,000 IU. Low levels are associated with thinning and loss.
