Receded temples? Yes.
However - it's way to early for you to go on any drugs. First, you need to monitor your hairline and thickness for several months before going on a routine. At the moment, your hair looks great - don't worry about that. The drugs used to treat male pattern baldness can have very serious side effects - especially finasteride. While you'll definitely read some reports that say only a very small minority suffers from serious side effects, that's most certainly not the case. It's unlikely that you'll escape side effects. If you're lucky it will only be watery semen and a slight loss in sex drive, if you're unlucky you might become impotent, sterile or perhaps suffer from permanent brain fog. And remember: the side effects can outlast the treatment. So it's not something that you want to take lightly.
While it is true, as some people on here are keen to remind you, that hair loss more than likely won't be reversed by meds, you'll need to resist the temptation to hop on meds that could seriously change your life for the worse without considering the potential consequences. Monitor your hair for at least 3-6 months and if you notice any rapid changes, then it might be time to consider going on a treatment. And of course, talk to a doctor about the meds.
I'm in a very similar situation to you at 24 (but I've started shedding a lot of hair the past month, so I might be worse off) and I contacted a doctor very early after realizing I was losing hair. People online told me to hop on finasteride right away to preserve my hair and that it was completely safe etc, so I thought "why not?". My doctor pretty much told me that she would prescribe me finasteride if I absolutely demanded it, but that the side effects can be absolutely devastating and it's not something to just hop on casually without truly considering what's at stake. I had read about some side effects on here and on other sites, but I didn't realize how bad and how common they were. So I put it off, went home and researched and decided to wait with the finasteride unless my hair gets a lot worse REALLY fast. Maybe I won't hop on even then, I'm undecided.
Think of it like this: these meds are dangerous for you. And they're expensive. They're not something you want to stay on forever. The majority of men lose their hair at some point, and you're one of them. If you go on finasteride right now, how long do you plan on staying on it? Five years? I can tell you losing your hair at 24 is f*****g awful still. 10 years? It's probably still just as bad. And then you've spent 10 years on a med that seriously fucks with your hormones and thousands and thousands of dollars. Want to start a family sometime in the future? It's not worth jeopardizing for a few years more with hair. If it's in the cards - which it seems to be for both of us - then you'll lose your hair eventually. Really consider how big of a risk a few extra years of hair is worth.
I've studied my family history a lot since I first noticed my own hair loss and I can tell you that not everyone who starts losing their hair early goes bald in a matter of years. My grandpa was at about the same place that you and I are at right now in his mid-late twenties - noticeable recession at the temples - but his hair loss progressed very slowly and he still has a good amount of hair at 90 today.
Losing your hair sucks. It's awful and it's hard to cope with. But if you ask me, trying to find ways to cope with it is the way forward, not the meds. Hopefully, your hair loss will progress very slowly. I hope this wall of text was helpful to you.
