Re: Why do i have no armpit hair even though I've gone through puberty?

Well, because you have NOT gone through puberty yet.  If I were you, I 
would not worry about not having armpit hair until I am 18.

Chris, I got the information below from this website:
 http://www.101corp.com/hair.html

"Male hormones or androgens regulate hair growth. Pubic and axillary 
(armpit) hair are particularly androgen-sensitive and grow at lower 
androgen levels than hair on the chest or legs. In boys, most pubic hair 
is grown by age 15, followed by the development of armpit hair two to 
three years later. In girls, too, an increase in androgens at puberty 
triggers growth of pubic and armpit hair. Scalp hair, not directly 
androgen-responsive, is influenced by local amounts of a testosterone 
derivative, dihydrotestosterone."
