I'm 19 years old, and my hairline has always been highish genetically, but my hair is very long and thick so I never really noticed as its always covered. I've been reading on the internet recently about hair loss, and had a look at the hair on my temples. I noticed thinner hairs around the partings. I might just be paranoid and they've always been like that, but is this just a maturing hairline, or is it miniaturisation?
