Am I losing my hair?

Hi all,

Just a quick one.

I’m 17 and noticed that my hairline isn’t like all my other friends or close to anyone my age. As you can see on the photos it is going back on one side which I think is very very noticeable and it makes me insecure in wearing my hair up.

I’ve also noticed that the right side of my head (at temples Slightly above ear) it’s a lot thinner than the other side.

Can anyone tell me honestly if I’m losing my hair or not?
