This book covers advances in treatment of hair loss and hair diseases over the past 50 years. It includes the changes in the methods used in surgical hair restoration from plugs to individual hairs, from manual punches to robotic surgery. It covers the first FDA approved treatment for hair loss - Minoxidil - and the first approved medication to prevent baldness - Propecia. It will also cover newer, non-prescription treatments such as Low Level Laser Light, Platelet Rich Plasma, and Photomodulation. Other conditions covered will include alopecia areata, frontal fibrosing alopecia (a new disease to dermatology), as well as chapters on hair follicle research  and cloning of hairs.
