I've watched videos by Dr. Blake Bloxham and I think he said that he accepts younger patients, but you need to have realistic expectations.
Also you will probably have to do FUT with him. He is recommended here and has a youtube channel where you can see some of his results, so maybe it's one to look out for.
Outside of US, I have seen Eugenix doing surgeries on younger guys or dr. Zarev (but you will have to wait 2-3 years).
There a few other doctors that may accept you despite the young age (doctors that can actually manage your donor well, not hair mills).
By the way you speak you sound very inpatient and at 23 even if you haven't noticed much progression in the last 2-3 years, it's still very young. You have higher chance of going NW5-6, so if you are going to book a transplant do it with someone that does those type of surgeries - Zarev, Eugenix, Hattingen. And if you have to wait 2-3 years for those doctors then my advice would be to do it.
Good luck.
