20 y/o and Possible start of MPB? Someone help

[Ruger]

Hi guys,

First off let me start by saying thin hair and mature, Dan Aykroyd-esque hairlines runs in my family but MPB does not run in neither my mothers or fathers side of the family.

Recently I was looking in the mirror and noticed one side of my crown is a bit thinner than the other, I’m not sure if this is just the natural way my hair has grown or if it’s the first sign of MPB. Any answers are more than appreciated as this is really starting to stress me out
