Hair Transplantation is a surgical technique that involves moving donor hair follicles which are genetically resistant to balding to the recipient balding areas of the scalp. The transferred tissue is not rejected as it is not foreign tissue. It retains its own characteristics, color, texture, growth rate and curl after transplantation and re-growth.
Hair transplantation, when done right, can be so natural that even your hair stylist will not know that you've had it done.
