Trends in Human Hair Growth and Alopecia Research

The document summarizes a collection of papers from The Human Hair Follicle in Biomedical Research Symposium in 1988, which focused on the study of human hair growth and involved collaboration between dermatologists and the pharmacological and cosmetic industries. The book covers topics such as the embryogenesis of the hair follicle, hair cycle patterns in different species, and the molecular markers of the eight hard α-keratins in hair and nail differentiation. It highlights the diversity in hair cycle patterns, with humans and guinea pigs having a mosaic pattern, rodents a wavelike pattern, and other mammals a synchronous pattern, while some species like merino sheep, angora rabbits, and poodle dogs do not exhibit a clear pattern or molting.
