Is my thin hair issue going to be a problem with finding someone?

[RedHood]

So I get my thin hair from my mother. I'm 17 and some people think that I'm prematurely balding, as it's only where my hairline starts. We all joke about it at school and I don't mind the jokes, but sometimes when attractive women point it out and say it negatively, it makes me wonder if this will give me an issue later on with a girl that I end up interested in. I can fix it to the point where it isn't as noticable, but I don't fix it because I don't want it to be a daily hassle.

So does it take away from my looks? I'm not saying it like I'm Mr. Hot sh*t, I've been told I'm about average, but will this... I don't know how to really say it... hinder me when it comes to my looks?
