Western medicine does not have all the answers. This said, there have not been any natural supplements identified as effective in regrowing hair for alopecia areata patients. Some natural health experts have recommended the use of supplements that are attributed to overall skin, hair, and nail health, such as biotin & other B vitamins, vitamin D, vitamin C, zinc, calcium, omega-3 fatty acids, and probiotics. Always consult with your primary care provider before starting any new supplements as they could interfere with other medications.
