I know, I know, you guys are probably INUNDATED with this question...

As for jsewell94, I can see why you are concerned because 17 is a little early of an age to develop a mature hairline however that does not mean that it will escalate to male pattern baldness. A few guys from my high school class had similar hairlines and now a few years later are not any more bald. You could easily maintain your hairline for quite a few years before it worsens at all. I wouldn't start with any medications or topicals but do keep an eye on it, especially the density at the vertex and mid anterior. DON'T OBSSES OVER IT

And oh yeah, I don't see anything wrong with a mature looking hairline, it looks more mature, just as its name implies.
