Green tea is popular worldwide for its health benefits and it is packed with antioxidants that fight free radicals, disrupt the production of bacteria and produce cancer-fighting flavonoids. The Department of Dermatology at the Seoul National University College of Medicine reports that green tea may also stimulate hair growth. Please note that green tea and green tea extract have not been evaluated by the Food and Drug Administration and are not considered a cure or treatment for any condition or disease. If you are experiencing an excessive amount of hair loss or particularly slow rate of hair growth, please consult your physician.
Stimulates Hair Follicles
According to the U.S. National Library of Medicine, a 2007 study by Korean scientists at the Seoul National University College of Medicine found that epigallocatechin-3-gallat, or EGCG, present in green tea promoted growth of hair follicles and stimulated the human dermal papilla cells to boost hair production.
According to the University of Maryland Medical Center, green tea can increase your metabolism. A faster metabolism may increase your hair growth rate.
While green tea may stimulate your hair follicles and make your hair grow faster, it is not necessarily useful for treating androgenic alopecia, which is a genetic hormonal hair loss condition. The Korean study notes that green tea may have potential to inhibit 5-alpha-reductase, the scalp pathway that converts testosterone to DHT and leads to hair loss.
