I believe, one of the most important things about looking youthful is to have a modern haircut. These guys are the best in doing so. I really love their job.
When I was 14, I thought I looked terrible. I wore these typical Slavic shoes with metal bottoms so you could always hear me coming and this really ugly.
In my twenties I would be skeptical of a bad haircut, but once you turn thirty it's more about whether he a nice person and does he open the door for me.
