Rogain is an FDA-approved solution that has been medically proven to regrow hair and revitalize hair follicles through daily application of two drops to the scalp. Hair transplants, which involve moving hair follicles from a donor site like the back of the head to bald areas, have also proven successful in treating baldness, though they may be costly. Natural remedies for hair loss prevention include using warmed green tea bags rubbed on the scalp for an hour to boost antioxidants or getting daily scalp massages to stimulate circulation.
