I'm 14 yrs old and have droopy nose. Am I too young for a nose job?

Rhinoplasty for droopy bulbous tip in 14 year old female is fine. I have done this for 35 years without problem. 

it sounds like you are physically mature. And possibly emotionally mature as well. Though 14 is a tad bit young. I think it is fine to start getting some consultations and to start going through the early process. It is important that your facial growth is complete, or nearly so, before surgery. Good luck.
