Hair transplants are illusions, not cures; not only do they not grow hair, they often cause additional loss. I see the appeal for middle NWs, but in the end, it’s just a redistribution. I imagine they’re still a thing because there is an unlimited supply of recently divorced 40-somethings.
For me, it's all about the cosmetic reward you'll actually get for the risk and price involved.
Looking at so many photos from clinics, which are mostly of 40-something patients, probably about 75% of them the guy is still clearly balding after the fact. Like, he was NW4 with a lot of diffuse and now he's NW4 with a little bit less diffuse: 2000 grafts/$10,000 FUE or something like that. Like, wtf was the point?
