It is believed that our groin hair has stayed thick (while most of our body hair has thinned out over our evolutionary time) so that it can release pheromones and attract mates, and your beard does it, too. Sebaceous glands are higher on your face than your scalp, Buka said, which leads to an increase in sebum, which carries pheromones. And since it's richer in sebum, and richer in pheromones, your beard has a distinct smell. "Your signature smell comes more from beard hair than from scalp hair. The base of a hair follicle is much bigger on your face, which is why it looks thicker on your face than your scalp hair. But it’s considered the same type of process, slightly different growth rates but same morphology otherwise," Buka said. In conclusion: If you have a beard, you have pubes on your face. Or, maybe your privates have a little beard on them down there. But for what it's worth, does Buka personally refer to beard hair as pubic hair? "No, I do not," he said.

They just don't want to admit that beards are pubes.
