Right now I'm 17, almost 18 years old. I still have a good amount of hair but it's deffinetly going away. I have a pretty bad receeding hairline, and the area around that is deffinetly going thin. Right now I have medium length hair, and usually sport a baseball cap. I'm sick of hiding it, was thinking of shaving it very short, or maybe even all off. Should I wait untill I lose more hair or just do it now? I'm just finishing up my junior year in highschool and I'm scared how people will react.
