Green tea contains elements that reduce our body's levels of the hormone DHT (dihydrotestosterone), a substance that encourages hair follicles to shrink. So it's an instant lash booster! Simply prepare a cup of green tea, let it cool, then dip a cotton swab in the liquid and use it to moisten your eyelashes. Do this 2-3 times a day for about 15 minutes of exposure each time, after which you should rinse your lashes thoroughly with water.
