Hair health is a core benefit of products produced for consumers by the cosmetic industry, and more than 70% of women claim to want healthy hair. However, there is very little clarity in the industry as to the meaning of healthy hair in a consumer context and the technical factors that control what the consumer perceives as hair health. Providing updated information on how to prevent and restore hair damage, Healthy Hair characterizes the clinical, physical, and chemical properties of healthy hair. Factors that control a woman's perception of healthy hair are described, and how these factors link to the fundamental biology of the hair fiber are explained, as well as insults to hair, such as brushing, coloring, and UV exposure. The influences of different products on hair health are discussed, and methods used to measure healthy hair at the molecular, single-fiber, and consumer levels are described. Hundreds of high quality color pictures illustrate the most important clinical, dermoscopic, and microscopic characteristics of both healthy and unhealthy hair.
"Bio-Stabilization Case Studies: Treatment and Performance Evaluation" describes and evaluates 30 projects from across the United States where bio-stabilization was employed to address a detrimental naturally occurring process or byproduct of the built environment. Bio-stabilization (or soil bioengineering) refers to the use of plant materials, primarily live cuttings, arranged in the ground in different arrays to reinforce soils and protect upland slopes and/or stream banks against surficial erosion and shallow slope failures. Examples included in the collection represent different regions of the country and their specific conditions and challenges. Each project is illustrated with a number of distinctive photographs to support the reader's understanding and showcase the wide scope of projects and techniques presented. The volume is ideal for civil and environmental engineers and environmental scientists working on watershed, infrastructure projects, and municipal scale installations.
