Why is pubic hair and armpit darker and curlier than leg hair and arm hair
Soso answered
Pubic and underarm hair look darker and curlier because they are a completely different type of hair that grows in response to puberty hormones.
When puberty starts, hormones kick in and tell specific hair follicles around your body to change what they are doing. The fine, soft hair that covers most of your arms and legs is called vellus hair. But in your armpits and pubic area, puberty hormones turn those follicles into makers of terminal hair. Terminal hair is thicker, has more pigment (which makes it look darker), and usually grows in an oval shape, which causes it to curl and kink as it grows out.
What body hair is doing there
Body hair actually has a job. It acts like a soft cushion to protect delicate skin from friction when you move around, walk, or run, and it helps trap your body's natural scents.
Having darker, thicker, or curly hair under your arms and on your private parts is completely normal. Breasts usually start growing first, and pubic and underarm hair appear shortly after, though getting hair first is totally normal too. Signs of puberty that started before age 8 are worth a check with a grown-up, and it is usually nothing to worry about.
