Excessive Hair Growth in teenage girl
I'm posting this on behalf of my girlfriend..
She has a bit of excessive hair growth across her chest, upper lip, back (especially lower back). Her navel has a thin line of hair that runs all the way down from her chest right through the middle. It's nothing serious, no big deal, but if there's a hormone issue that could cause problems later, it's something she wants to resolve.
A little physical background on her, just to try to rule somethings out. Her cycle started only just over a year ago. She is a bit underweight (17.1 BMI). Her breasts started developing pretty late as well, and are A cups right now.
