Why Some Men Can't Grow Beards

We asked a dermatologist to explain the scientific reasons that some men aren't able to grow thick, dense facial hair. Dr. Jennifer Chwalek is a Board Certified dermatologist at Union Square Laser Dermatology in New York. Chwalek explained that an inability to grow thick facial hair is not directly related to low levels of testosterone. Facial hair growth is largely determined by genetics, which can determine the number of hair follicles a person has, as well as how the follicles react to a byproduct of testosterone known as dihydrotestosterone. ------------------------------------------------------ #Beard #FacialHair #ScienceInsider Following is a transcript of the video: Narrator: Look at that beard. The density. The thickness. It's what a beard is supposed to be! Not this. This is my beard, if you even want to call it a beard. This footage was taken after I let it grow for two weeks. Two weeks! It's thin, patchy, and in some spots there's no hair at all.
