Will it be painful to get a hair transplant surgery?

Hoping to god my hair genetics are better than my grandfather on my mothers side. Not complete balding but definitely a recessed hairline. Hoping I get my father's side of hair genetics. No balding.

Hopefully taking my hormones artificially will ironically keep them at a more consistent level rather than natural degradation.

Theyre actually surprisingly affordable. I wouldnt mess with it if you have thin hair in the back or rapid hairloss. I think it would work for me because I got the same widows peak as my dad and hes in his 60s and hasnt lost any more.

I'll probably need one in about 5 years, my hair's been falling out since I was 26.
