I was reading on Google News last week that scientists have discovered that mice are capable of regenerating hair, white hair, when they slice a chunk of skin and fur away from the mouse.

The wound heals and instead of leaving just a scar it eventually regenerates hair over the scar.  The hair has no pigment and therefore is white.

I'm sure there is going to be a day when I will need some of my hair replaced.

I don't think that I really want to have legions of mice suffer lesions in their skin so that I can defy aging and balding.

I might opt for a transplant of my own hair from some hair  transplant doctor such as Dr. Larry Shapiro or hopefully something even better might be discovered without having to torture living creatures.
