I have had three transplants and am very happy with the results. I had my first one back in 1990, my second was 5years later, and my last one was in 2007. I realize it is necessary to continue the sessions as hair loss occurs. This is an on going journey of losing hair and replacing it with new hair. Only one treatment usually is not enough, as we grow older, we tend to lose hair and I have made the choice to plant new growth. I was happy with my first session for 5 years but I needed more as I grew older. I am sure I will get more planted in the future. It is all about building hair, it isn't a magic bullet.
