No real history of MPB in family other than normal hair loss after ~50 years old. I am 23 and was fat all of my childhood. I lost about 70-80 lbs in under a year and a half about 2-3 years ago. I basically lost it in the worst way possible… starving, keto, etc. Barely functioned during that time. Since then my hair seemed noticeably thinner on the entire hairline and crown a bit. However, it seemed to get bad and then stay the same since then. Hasn’t really gotten worse. I read that weight loss can trigger MPB somehow. Does this mean I’m basically starting now what I would start at 45/50 years old? Does it necessarily mean it’s going to keep getting worse? Or is there a chance it’ll take some time? I’d really rather get a hair transplant than take drugs daily.

Significant weight loss causes hair loss. 30 pounds in a month is very extreme. A safe number is 1 pound/week and should reflect a new lifestyle of eating, not crash dieting. Even though your family history doesn’t show balding, you have developed a Norwood Class 3 Vertex pattern of balding which was mot likely accelerated by your crash diet.

Hair transplants generally last your lifetime. I have seem patients I performed hair transplants back in the early 1990s when I started performing FUT procedures and they still have their hair, most of them. A few have come in because further hair loss of their original native hair brought them in. A small percentage of patients do lose their hair transplants, less than 3% I would guess

This 24 y/0 man was on finasteride and minoxidil for one year and reversed the miniaturized hairs in the forelock and filled in the area behind the forelock that was bare.  The corners are still not present and if he wants a normal hairline, I suspect that only a hair transplant will do this

24 y.o., just took the plunge with half a tablet of 1mg fin

You should get metrics so you know the impact of your treatment. get a HAIRCHECK test ( https://baldingblog.com/haircheck-test-how-it-is-done-video/ ) and then repeat it yearly to see if you are getting better or worse. You don’t want to gamble with your future hair coverage. Why not use the recommended 1mg dose which is the most effective dose of finasteride?

This is an old wives tale. It is the hair that generate the blood supply. The human body is smart and supplies blood and oxygen to needing tissues. We see that when balding occurs and the hair is lost on some area of the head, the blood flow to the balding area slows down proportional to the loss of hair.

The question I would ask if he really received 8874 grafts in two sessions?  A failure of this magnitude reflects a very poor delivery organization for hair transplants. The hairline itself is designed as a female hairline, not I suspect what he thought he was going to get
