Book Description
Several years ago a friendly looking young man walked into my office at the University Department of Dermatology in Cologne, introduced himself as a diplomate chemist, executive member of a family-owned, rather small German company manufacturing hair care products, and proposed to me straight forward to organize an international meeting on hair research. In view of the large number of new developments in the field something like this should be done after all, he said; he also promised to provide financial support. Such a meeting should be on the highest possible level, I said; and he agreed. I took the challenge and my visitor kept his promise. Three years later the First International Hair Congress was organized at the sophisticated new Congress Center in Hamburg, in which 630 participants from 36 countries were registered. After three and a half days of formal sessions, informal discussions, workshops and poster presentations our unanimous feeling was that this has been a most successful meeting. The young chemist was right. The idea was excellent. The growth and presence of hair and its distribution over the human body as a cosmetic attribute has become during the last two decades a matter of tremendous emotional significance. Hair can be rather easily formed according to one's sence of style, representing his personal image and his social feeling. If it becomes unacceptable or out of fashion, the hair style can be easily changed; the hair regrows as a biological requisite, without any additional cost.

Book Description
Human hair is the subject of a remarkably wide range of scientific investigations. Its chemical and physical properties are of importance to the cosmetics industry, forensic scientists and to biomedical researchers. The fifth edition of this book confirms its position as the definitive monograph on the subject. Previous editions were recognized as “concise and thorough” (Journal of the American Chemical Society), “an invaluable resource” (Canadian Forensic Science Society Journal), and “highly recommended” (Textile Research Journal). Chemical and Physical Behavior of Human Hair is a teaching guide and reference volume for cosmetic chemists and other scientists in the hair products industry, academic researchers studying hair and hair growth, textile scientists and forensic specialists. Features of the Fifth Edition: Recent advances in the classification and characterization of the different proteins and genes in IF and keratin associated proteins in human hair are described. The mechanism and incidence of hair growth and loss and hair density vs. age of males & females are described for Asians, Caucasians and Africans in different scalp regions. Details of hair surface lipids and cuticle membranes provide a better understanding of the surface and organization of the CMC and its involvement in stress strain is presented. Recent evidence demonstrates a more bilateral structure in curly hair and a more concentric arrangement of different cortical proteins in straighter hair. SNPs involved in hair form (curl and coarseness) and pigmentation and genes in alopecia and hair abnormalities are described. The latest biosynthetic scheme for hair pigments and structures for these and the different response of red versus brown-black pigments to photodegradation is described. A new method for curvature on 2,400 persons from different countries and groups is used to assign curvature throughout this book. Additional data for age and effects on diameter, ellipticity, elastic modulus, break stress and other parameters are presented with much larger data sets featuring statistical analyses. Hair conditioning, strength, breakage, split ends, flyaway, shine, combing ease, body, style retention, manageability and feel parameters are defined and described. A new section of different life stages by age groups considering collective and individual changes in hair fiber properties with age and how these affect assembly properties.

Book Description
It is now thirty years since William Montagna and Richard Ellis edited 'The Biology of Hair Growth". In his introduction, Stephen Rothman, of the University of Chicago, USA and one of the driving forces behind research on skin at the time, wrote: 'The pilary system is a perfect micr9cosmic structure. In this microcos mos we find birth, development, ageing and death, activity and rest, color for mation and decolorification, greasiness and dryness, infection and sterilization, hypertrophy and atrophy, Qenign tumours and malignant ones." He foresaw the human pilary system as a model for the study of a multitude of human diseases including ageing and cancer. It was not, how ever, until the seventies that the development of micro-biochemical tech niques indeed allowed the use of the human hair follicle as a convenient biopsy tissue for Biomedical Research in general. Measurement of enzyme activities, and important co-factors, and culturing of cells from single follicles all became possible. In the eighties dermal papilla cells were grown in cul ture and this opened the way to study hair differentiation in vitro. Studying hair differentiation is, in fact, studying growth regulation and it is this aspect that by far transcends the importance of studying hair growth itself. Let us not forget that metastatic prostate cancer is treated with the same drug -cyproterone acetate -that is used for the treatment of alopecia and hirsutism in women.

Book Description
The quantity and quality of the hair are closely related to the nutritional state of an individual. And yet, there is hardly another field with so much prejudice, misconception, and debate as diet and health, let alone hair health. Pharmacy aisles and Internet drugstores are full of nutritional supplements promising full, thick, luscious hair for prices that range from suspiciously cheap to dishearteningly exorbitant. Since there lies an important commercial interest in the nutritional value of various nutritional supplements, a central question that arises is whether increasing the content of an already adequate diet with nutrients may further promote hair growth and quality. This book aims at distinguishing facts from fiction, and at providing a sound scientific basis for nutrition-based strategies for healthy hair, at the same time acknowledging the problems and limitations of our current understanding and practice.

Book Description
This book aims to comprehensively review the current cell-based strategies under investigation to achieve the regeneration of human hair follicles. The unique capacity of the human hair follicle to self-renew explains why this complex “mini-organ” has always attracted so much interest as a model for researchers to study stem cell biology and regenerative medicine. The hair follicle is considered a main reservoir of cutaneous stem cells, containing several pools of epithelial, melanocyte, and mesenchymal stem cells involved in hair follicle self-regeneration and pigmentation. In addition, while some of the different follicular cell types contribute to hair shaft growth, others participate in very important interfollicular functions such as dermal remodeling, re-epithelialization after wounding, and cutaneous stem cell homeostasis. The idea of human hair follicle regeneration either “de novo” or by activating dormant miniaturized follicles is not new, yet still continues to arouse enormous interest in the pursuit of a definitive cure for baldness. In contrast to hair follicle regeneration in mice, the attempts made with human follicles have been disappointing in terms of efficiency. However, recent advances in stem cell biology—as well as the appearance of new technologies like 3D printing—have revived expectations in this field of research. This book is divided into four sections. The first part includes an overview of the strategies used in hair follicle regeneration and a historical summary of the most important achievements to date. Parts two and three comprise the main body of the book, with detailed descriptions of the cells and tissue structures involved in hair follicle regeneration, followed by an elaboration of the different therapeutic strategies, engineering techniques, and a clinician’s perspective of stem cell-based therapies in hair loss treatments. Finally, the fourth part reviews the important contribution of the hair follicle in healing cutaneous wounds through the regeneration and remodeling of the dermis and epidermis after injury, as well as wound induced hair follicle neogenesis that occurs when the skin is injured.
