I'm 19 years old, have had a pretty much normal and natural puberty thus far as far as I know. My voice has deepened already, I've experienced all the normal testosterone changes and the hair on my body is growing naturally.

Lately, I've noticed that I have a few long blond hairs on my chest. I have dark hair, but about 10-15% of the hair on my body is blond, it's pretty much scattered around the darker hair and is mostly noticeable when I hold my arm up too the light.
I'm getting a little concerned with some of the blond hairs, the hair on my chest is about a centimeter long, while the few blond hairs are around a centimeter and a half long. My concern is that in a year or two I'll have to trim the blond ones. Or will it all even out, or is this superficial on my part?
Thanks in advance.
