Alopecia areata is a type of hair loss that flares when the immune system gets confused and starts attacking hair follicles. The cause of the condition is still a mystery -- but the result is tough-to-cover bald spots that can be even tougher to cure.
If you’ve been diagnosed with this frustrating condition, consider trying a manganese supplement. European studies suggest that almost 100 percent of people with alopecia are deficient in this mineral -- and taking supplements helped some of their bald spots fill in within just four months! The study-proven dose: 10 milligrams daily. Reputable brands include Natrol, Bluebonnet and Twinlab.
