No you dont. its just the speed in which your body grows!
No some people just don't get underarm hair.
No, you don't have to have underarm hair to start your period. Everyone develops differently and at different speeds.
No, not always. I started getting pubic hair when I was 8 and didnt get my period until I was 13.
You go through growth,acne,pubic and underarm hair,greasy hair,breast growth,you get curvier, and,of course,your period
Underarm hair can be removed either by waxing or shaving. Generally, men do not remove their underarm hair, but women do, and tend to prefer to shave as waxing can be very painful.
no
Yes, the rest will fall into place.
Shave it
Yes. Underarm hair is a trivial thing and doesn't affect how a person looks. There are people out there who like it and of course there are others that don't. Shaving underarm hair is a personal choice and this choice should not be made based on other people's opinions. Do what feels best to you.
they are strting to go through puberty (tons of pubic and underarm hair, period, pimples, all that gross stuff)
You may notice a clear substance, called discharge, on your underwear. That's one sign. Another is breast development and hair under your arms or your bikini line. But it doesn't mean you have to have hair in those places before you get your period. I didn't start getting underarm hair until well after I got my period. Hope I helped! :)
Your hair expels everything that goes in your body, all of your hair.
