Some men are blessed with fast-growing facial hair, while others may struggle with slow-growing or patchy whiskers. The rate that your facial hair grows depends mostly on genetics, but if you are anxious for your beard to come in, there are a few tricks you can try to maximize growth rate and fullness. To grow a beard faster, care for your face by cleaning, moisturizing, and exfoliating properly, take biotin or other vitamin supplements that encourage hair growth, and leave your beard alone as it starts growing in.
