Huh? It's not a secret and people do and are rich for reversing baldness. It's called hair implants.


Not to be rude, but what personal experience do you have with baldness? My guess is none since you said you have good hair. Money buys a lot of things including doctors who scam folks into thinking they can restore the full head of hair one had in their youth. Whoever develops a real remedy for baldness, will become incredibly rich.
Implants only work when there is enough hair to implant. People with very fine and thin hair aren't good candidates for implants.
Limitations of Hair Transplants:
Limited amount of hairs genetically resistant to hair loss in the donor area.
Particular to follicular unit extraction (FUE) surgery, donor hairs can be taken from outside the genetically resistant area which will continue to thin and eventually be lost
Large bald areas that patients desire to have covered cannot be transplanted to full coverage
Insufficient density of transplanted hair
The need for repeat hair transplants due to continued hair loss (Hair transplant does not stop hair thinning).
