You're actually better off with shorter hair.
My hair is beginning to thin so I have to cut it shorter. Even people who don't go bald have a receding hairline at the front. For real I remember as a kid, that my hairline on the top and sides matched. Now the hairline on the top has receded and of course, I have this kind of point on the sides. Apparently its totally normal because every dude has one. When it happened to me I was like what the hell when did that happen!? Then I realized everyone gets it.
