Check out Kevin Costner’s hair. It was receding pretty badly at one point and seems to have miraculously grown back. I suppose we can attribute that to the powers of having a hot young wife more than 20 years your junior (sort of like at ‘at home fountain of youth’).
Other men with receding hairlines indulge in the wonders of hair implants. Up close, the implants basically look like plastic baby doll hair. Even when finely spaced, you can see where the hair is ‘plugged in’. However, from a distance, the implanted hair can look real.
