A crash diet at age 19 left Richard Simmons bald, says the fitness guru. Which is, in essence, why he has such crazy, curly hair today. Sound strange? It is.

Simmons said he had 4,000 hair follicles transplanted after his unfortunate hair loss 41 years ago. The result? That massive head of hair he has today.

Simmons' story comes up as part of a larger story featured in USA Today about hair transplants that require the transplantation of only 120 follicles, and not the current standard of 2,000. Hair regeneration therapy is the name of this hairy breakthrough, and Intercytex is the company trying to market it. Studies show 11 of 19 men who have tried the procedure have successfully grown hair six months after treatment.
