Okay i'm 19yrs old and i have no facial hair. so how do i make it grow?

Facial Hair: If your facial hair comes in slower than you would like or if you are trying to give the appearance of more facial hair, there are a few options that are worth a try. Whether you choose testosterone treatments or over-the-counter applications, results vary from person to person---and some individuals may ultimately find it impossible to grow facial hair or increase the rate at which it grows.
