Abstract
In the main, the development of modern hair restoration surgical techniques has involved a few revolutions and a number of small evolutions. These evolutions have improved upon earlier techniques after carefully analyzing both the benefits and shortcomings of these pioneer techniques.

Modern megasessions require a gradual increase in graft numbers to accommodate the need for development of staff skills unique to these procedures. Innovation is important, but it is more safely expressed in gradual improvements to existing techniques.
