Our bodies just produce a lot of DHT during puberty, but that goes down after that. It is possible that had a temporary effect
on your hairline. You're not delusional. Asking questions is a sign of intelligence.
The truth is you know your own hair better than anybody else. Let me explain. You know if your hair is shedding more in some areas than others.
In any case, it takes a long time for androgen alopecia to cause permanent hair loss. It takes years, and it is only irreversible if you have
no terminal hair growing in the spot. Usually it takes around five years, on average.
My friend who got the good hair genes has a Norwood 1 hairline. He is in his 60s, and still has all of his hair. He has diabetes, so
I wouldn't say he hit the "gene lottery".
