You hair in general is great but doe look like minor recession around the temple area....I would take more pictures close up.
You have many options obviously the main one for male pattern baldness is the BIG3:
Finasteride
Minoxidil
Ketaconazole
Derma roller
I use that in Topical lotion or you can buy separate and take in pill form, see my thread:

When he starts shedding his existing hair it’ll be hard to regrow.I would agree with poster above till where he advised you to take finasteride, I would say instead just keep an eye on it. When you start shedding or notice changes in the hair then come back to us, if not enjoy your life mate.
