My friend was about a NW4 12 years ago when he got a hair transplant at age 29. His hair looked fantastic afterward and he got the confidence to date and be social. 6 years later he got another smaller transplant at age 35. Yes he's on Fin and now at age 41 he still has a relatively full head of hair. If it only buys him another 5-6 years that would be a total of 18 years with hair. I'm not saying that's the case. He may keep most of his hair for another 20 years (who knows). He definitely doesn't regret it. He's living his life and enjoying it with a bit more confidence. I guess that's why people do it.
