Q: Dr. Bernstein, I remember Senator William Proxmire. He was one of the first sort of high-profile people who had a hair transplant probably, what, thirty years ago, and to be honest with you, it wasn’t all that great. It looked kind of funny. Have we made any progress in the last twenty-five, thirty years? — A.E., Fort Lee, N.J.

A: When hair transplant surgery was first developed in the late 1950s, early 1960s, everybody was so ecstatic that it grew – that one could actually move hair from the back of the head to the top, and it would grow – that no one really considered either the long-term implications or the aesthetic aspects of the procedure. And the fact that the hair grew is actually a problem because it never went away when it was transplanted poorly.

Over the years the grafts have gotten smaller and smaller. So where in the ’60s and ’70s they were the size of pencil erasers, they gradually decreased in size until doctors were performing hair transplants using just a few hairs at a time. The major breakthrough came in the mid 1990s when we realized that hair doesn’t grow individually but grows in little tiny groups and these groups are called follicular units.

In modern hair transplant surgery (which began in 1995) hair is taken from the back of the scalp and moved to the front and top of the scalp in these individual groups of one to four hairs.

In this way the results can completely mimic the way hair grows in nature.
