Most of the contributors are from Europe, with one each from the United States, Japan, and the United Kingdom. The contents reflect the increasing collaboration between dermatological investigators and the pharmacological and cosmetic industries in the study of human hair growth.
Part I, Biology and Experimental Models, starts with a good description of the embryogenesis of the hair follicle and hair cycle. It is interesting to learn that the hair cycle pattern in man and guinea pig is mosaic, in rodents wavelike, and in most other mammals synchronous, but in merino sheep, angora rabbits, and poodle dogs it is not evident and molting never occurs.
