Buzzed my hair for first time in 15 years, looks like I'm diffuse thinning badly?

[confused101]

32 years old.
More or less always vigilant of my hairline, it feels like it's mostly stayed the same as when I was 18, maybe moved back just a smidge?
But decided to buzz my hair for the first time in 13 years, and holy jesus... looks thin/diffuse as hell to me. I got my girlfriend to take a look, she says it doesn't look thin to her, but to me it seems pretty obvious. So thought I would get the community's thoughts, I'm pretty much ready to hop on fin/minox right now (never been on either before).

First few pictures are from right now, then the most recent front photo of my hairline before the buzzcut, and I cropped some old photos from 2007 that show my hair the last time I buzzed it.

Also, how effective is fin/minox at targeting diffuse thinning in comparison to receding hairlines? Additionally, does the fact that my hair overall is not BAD for 32 (compared to aggressive MBPers who lose a lot in their 20s) mean with treatment, I could potentially keep my hair for longer?

Appreciate any input!

I think you should buzz even shorter

It doesn't look bad at all. I'd keep it that way.

My Mrs is trying to get me to do mine this week too with the sun being out... I'm resisting so far.
