To be quite honest, a perfect teenage hairline is the last thing I want. I like my high hairline. I would ideally thicken it and simply clean it up so it's less messy. High hairline works well with beards, and I always like it when people can tell I'm Irish at a first glance... So it all filters in quite well.. I'm simply trying to avoid looking like my biological grandfather, but I inherited most of his genes. A mature hairline with density far outweighs having a thin low hairline in my opinion. @Spanky, you're right though. I'm certainly going to keep it shaved until I can get a better idea of what it's going to do.
