Chemical and Physical Behavior of Human Hair

Human hair is the subject of a remarkably wide range of scienti- fic investigations. Its chemical and physical properties are of importance to the cosmetics industry, forensic scientists, and to biomedical researchers. The fourth edition of this book con- firms its position as the definitive monograph on the subject. Previous editions of this book were recognized as "concise and thorough". Features of the Fourth Edition: - New information on chemical damage from permanent waving, bleaching and sunlight and how to minimize or prevent this damage. - A new view of the cause of dandruff is presented with new supporting data. This view suggests new approaches for both treatment and for marketing of scalp care products. - The latest information on the science of hair growth and hair growth stimulating agents is provided, including Propecia. - A new section has been added on skin and eye irritation and skin sensitization from ingredients used in hair care, and a model has been provided to predict relative skin irritation of shampoos. - New micrographs on "normal hair fiber shape variations" and how fiber shape can influence chemical and physical interactions of hair fibers will be covered. - Additional material is now included on hair straightening.
