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.

Available in PDF, EPUB and Kindle. Book excerpt: The Biology of Hair Growth is based on a conference on The Biology of Hair Growth, sponsored by the British Society for Research on Ageing, held at the Royal College of Surgeons, in London, 7-9 August 1957. The papers presented at this conference, and a few others, have been gathered in this book to serve as a source reference for all those interested in research on hair and hair growth. The application of modern methods in histology, cytology, histochemistry, physiology, electron microscopy, the use of radioactive isotopes, and modern biochemical techniques have given greater insight into the phenomena of growth and differentiation of hair follicles than ever before. The book opens with a chapter on the embryology of hair. Separate chapters follow on the anatomy and histochemistry of the hair follicle; the electron microscopy of keratinized tissues; the chemistry of keratinization; the mitotic activity of the follicle; and the the vascularity and patterns of growth of hair follicles. Subsequent chapters deal with behavior of pigment cells and epithelial cells in the hair follicle; the nature of hair pigment; the effects of nutrition on hair growth; and effects of chemical agents, ionizing radiation, and particular illnesses on hair roots.

Download or read book Chemical Analysis of Proecessed Human Hair Extentions for Use in Forensic Casework written by Courtney Schartz and published by . This book was released on 2019 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: In forensic laboratories, hair analysis is performed in the trace evidence unit and the DNA unit. The completed analysis of hair can include a variety of tests, but generally, microscopic analysis is performed and is followed by mitochondrial DNA analysis. With the increasing use of hair extensions, it is possible that a hair sample discovered at a crime scene may be a processed human hair extension and has no physical or genetic connection to the individual wearing the hair extensions. This can be misleading in an investigation and result in a misuse of time and resources. Being able to identify a hair as a processed human hair extension is valuable in determining its entire evidentiary value and result in the forensic laboratory adjusting its approach to analysis. Current literature is limited pertaining to hair extensions as forensic evidence. Only one study has focused extensively on processed human hair extensions for their probative value in forensic case work. This study involved the microscopic examination and genetic analysis of processed human hair extensions but found no features that differentiated natural human head hairs from human hair extensions. There are multiple articles that research chemical analysis of hair, but few are looking into applications into the forensic laboratory. The lack of literature proves the necessity for this research.This research determined whether a chemical difference was present between natural human head hair and processed human hair extensions through ultraviolet-visible spectroscopy, gas chromatography/mass spectrometry, and nuclear magnetic resonance spectroscopy. Three different hair extension brands and five different natural human hair samples were used in this research. Multiple organic solid-liquid extractions were completed using hexanes, Colorist SecretsTM Hair Color Remover, methanol, 1-octanol, and chloroform-d. The extraction solvents were then used for instrumental analysis by ultraviolet-visible spectroscopy, gas chromatography/mass spectrometry, and nuclear magnetic resonance spectroscopy. The resulting spectra were analyzed and compared to determine differences between processed human hair extensions and natural human head hairs. This study proves that there is a chemical difference between processed human hair extensions and natural human head hair. This was indicated by the differences observed in spectra on the UV-Vis, GC/MS, and NMR between the natural human head hairs and processed human hair extensions. The processed human hair extensions have a higher absorbance, when analyzed with UV-Vis spectroscopy than the natural human head hair samples. In addition, there are specifics in the processed human hair extensions that are visualized by GC/MS and NMR analysis that are not present in the control natural human head hair samples. The higher absorbance and peaks show a chemical difference between the samples. This chemical difference can be used to differentiate samples in a forensic laboratory, which could change how hair is analyzed for casework. This research is significant because it allows for the chemical identification of processed human hair extensions which may help in determining if the hair has probative value in a forensic case. The ability to chemically identify a hair extension collected from a crime scene would provide investigate leads and help to preserve time and resources. Also, chemical analysis might allow a processed human hair extension collected from a crime scene to be definitively associated with others from the same manufacturing package. This would be beneficial if the extensions were still attached to the suspect's head. This research has the potential to change the way that hair analysis is viewed and used throughout the forensic laboratory. Further research needs to be completed: analysis of more hair extension brands, determine a concise method of analysis, and the best extraction solvent. The study is a precursor to all of this and proves that there is a necessity for further analysis and implementation to forensics. But before any of that can happen, a reliable and consistent method needs to be determined and validated. This study proves this need for further research in this area, and ultimately updating the process for hair analysis throughout forensic laboratories.

Available in PDF, EPUB and Kindle. Book excerpt: Hair is a major component of the body's tissue system that contributes to the individual's make up and confers a large degree of personal identity. Apart from its visible façade, hair also has a functional role. It has an unique structure and complex molecular development. The very nature of hair makes it a suitable marker for the prognosis of disease. Hair can also be used to screen for toxins and changes in the diet. However, there are currently no suitable publications available that describe hair in a rational scientific context. This handbook provides an academic approach to hair in health and disease. Divided into five sections the Handbook of Hair in Health and Disease provides an insight into hair growth and loss, molecular and cellular biology of hair, dietary toxicity and pathological history, diseases and treatments of hair, as well as shampoos and conditioners. Unique features of each chapter in this volume include relevant and useful 'Key facts' which highlight interesting or important findings of the specific subjects and 'Summary points' that will give a clear overview of the subjects treated in each chapter. The Handbook of Hair in Health and Disease will be essential to a variety of users, such as trichologists, doctors and nurses and all those interested or working within the area of hair health. This includes nutritionists and dieticians, scientific beauticians, health workers and practitioners, college and university lecturers and undergraduate and graduate students.
