22 Year old male considering a hair transplant, advice would be appreciated

I've been steadily losing my hair since I was about 15 years old (unlucky genes I know) with my three older brothers all more or less completely bald now. I have managed to maintain a decent head of hair using minoxidil since I was about 16 but the naive me assumed there might be a cure by now! As there are no clear signs of a better alternative around the corner, I am starting to consider the possibility of a hair transplant. I've come to accept my hair loss over the years but I would love to be able to keep a decent head of hair in to my thirties.

I'm just hoping to get advice on whether this might be a good idea for someone my age and what things I should consider as well as potential surgeons in the UK. Looking at the Norwood scale I would say i'm probably between 2 and 3.

Any advice is welcomes and thanks in advance!
