18 (within months to 19).
Want to know if hairline is receeding, or if those thinner hairs are me being paranoid, tried to include a lot of images if any are bad / want diff angles, tell me.

With family history - brother is younger, father pictured here in his 50s

on mothers side theres my Grandad who isnt fully bald but has quite a lot of hairloss and there isnt much left on the top (dont know his age tbh, 60s?). Uncle passed away and never really met him ( was in the past few years, so if its neccesary could try and find out what his hair was like)


Basically, give it to me straight, am I losing hair and should I do anything or am I paranoid?

Don't think you are currently losing hair. The hairline looks solid.

If your dad is losing his hair (looked at the pictures), it's not that agressive.
His hairline seems good, especially for a man in his fifties.

Worst case, your hair loss, if you have any in your twenties, will not be
agressive. It looks like you have good genes.
