so, when you shave your beard, chest, armpits and pubes it gennerally leaves a stubble whereas when you shave the rest of your body it dosen’t
why is that? Shouldn’t you’re entire body be one way or the other?
In: Biology
There are two (main) types of body hair: “vellus” hair and “terminal” hair.
Vellus hair is fine, soft, and usually quite short. It’s the hair on places like the back of your neck. Pre-pubescent children and women tend to have more vellus hair. When you shave vellus hair, because it is short and fine, you usually don’t see/feel any stubble–the hair follicles aren’t thick enough to feel “spiky” like that.
Terminal hair is thick, darker, and usually wavy or curly. “Pubic hair” is terminal hair, but so is body hair, head hair, eyelashes/eyebrows, etc. Testosterone is partly responsible for triggering vellus hair to change into terminal hair, which is why post-pubescent boys and adult men have more terminal hair. Beard, chest, armpit, and pubic hair are all terminal hair. Because the hair is thicker and (usually) more curled, it will develop a noticeable stubble very quickly, as the short hairs resist motion against the grain.
