| chemistry of hair dye: True Roots Ronnie Citron-Fink, 2019-06-04 Like 75% of American women, Ronnie Citron-Fink dyed her hair, visiting the salon every few weeks to hide gray roots in her signature dark brown mane. She wanted to look attractive, professional, young. Yet as a journalist covering health and the environment, she knew something wasn’t right. All those unpronounceable chemical names on the back of the hair dye box were far from natural. Were her recurring headaches and allergies telltale signs that the dye offered the illusion of health, all the while undermining it? So after twenty-five years of coloring, Ronnie took a leap and decided to ditch the dye. Suddenly everyone, from friends and family to rank strangers, seemed to have questions about her hair. How’d you do it? Are you doing that on purpose? Are you OK? Armed with a mantra that explained her reasons for going gray—the upkeep, the cost, the chemicals—Ronnie started to ask her own questions. What are the risks of coloring? Why are hair dye companies allowed to use chemicals that may be harmful? Are there safer alternatives? Maybe most importantly, why do women feel compelled to color? Will I still feel like me when I have gray hair? True Roots follows Ronnie’s journey from dark dyes to a silver crown of glory, from fear of aging to embracing natural beauty. Along the way, readers will learn how to protect themselves, whether by transitioning to their natural color or switching to safer products. Like Ronnie, women of all ages can discover their own hair story, one built on individuality, health, and truth. |
| chemistry of hair dye: Colorants for Non-Textile Applications H.S. Freeman, A.T. Peters, 2000-05-03 This volume examines the chemistry of natural and synthetic dyes produced for non-textile markets, where much new basic research in color chemistry is now taking place.The first group of chapters covers the design, synthesis, properties and application technology pertaining to dyes for digital printing and photography. The reader will be pleased with the breadth and depth of information presented in each case. Of particular interest is the discussion of strategies for the design of dyes in these categories, with emphasis on enhancing technical properties. In view of certain new developments, the ink-jet chapter includes results from studies pertaining to dyes for textiles.The three chapters comprising Section II of this volume cover the broad subject of dyes for food, drug and cosmetic applications and then provide an in-depth look at dyes for biomedical applications and molecular recognition. The chapter on dyes for molecular recognition places emphasis on applications in the biological sciences, including sensory materials and artificial receptors. While the former two topics have been covered elsewhere in the past, the present chapters are unequalled in scope.Section III provides an in-depth review of the design of laser dyes and dye-based functional materials. In the first of the two chapters, the major principles of laser operation are summarized. This is followed by a discussion of spectroscopic properties, such as activation and deactivation of absorbed light by laser dyes. Approaches to the development of new laser dyes are presented. The second chapter pertains to the synthesis of dicyanopyrazine-based multifunctional dyes. The visible and fluorescence spectra of these dyes in solution and the solid state are correlated with their three-dimensional molecular structures. Molecular stacking behavior and solid state properties of these multifunctional dye materials are presented.The final group of chapters pertains to natural dyes and dyes for natural substrates. In recent years, the impression among certain consumers that natural is better/safer has generated much interest in the use of natural dyes rather than synthetics. This has led to a few short discussion papers in which the environmental advantages to using natural dyes have been questioned. The initial chapter in this group provides both a historical look at natural dyes and a comprehensive compilation of natural dye structures and their sources. Though natural dyes are of interest as colorants for textiles, selected ones are used primarily in food and cosmetics.Chapter ten provides an update on the author's previous reviews of structure-color-relationships among precursors employed in the coloration of hair. Chemical constitutions characterizing hair dye structures are presented, along with a summary of available precursors and their environmental properties. Similarly, the chapter on leather dyes covers constitutions and nomenclature, in addition to providing interesting perspectives on the origin and use of leather, the dyeing of leather, and key environmental issues.This volume is concluded with another look at colors in nature. In this case, rather than revisiting colors in plant life, an interesting chapter dealing with color in the absence of colorants is presented. Chapter twelve covers basic concepts of color science and illustrates how 3-D assemblies leading to a plethora of colors are handled in nature. It is our hope that this atypical color chemistry chapter will invoke ideas that lead to the design of useful colorants.The chapters presented in this volume demonstrate that color chemistry still has much to offer individuals with inquiring minds who are searching for a career path. This work highlights the creativity of today's color chemists and the wide variety of interesting non-textile areas from which a career can be launched. |

| chemistry of hair dye: The Chemistry and Application of Dyes David R. Waring, Geoffrey Hallas, 2013-11-11 It is particularly appropriate that a volume concerned with dye chemistry should be included in the series Topics in Applied Chemistry. The development of the dye industry has been inexorably linked not only with the development of the chemical industry but also with organic chemistry itself since the middle of the last century. The position of dye chemistry at the forefront of chemical 1945 and more markedly so during the last advance has declined somewhat since 15 years, with pharmaceutical and medicinal chemistry assuming an increasingly prominent position. Nevertheless, dye production still accounts for a significant portion of the business of most major chemical companies. The field of dye chemistry has stimulated the publication of many books over the years but surprisingly few have concentrated on or even included the practical aspects of dye synthesis and application. Thus, the present volume is designed to fulfill that need and provide the reader with an account of advances in dye chemistry, concentrating on more recent work and giving, in a single volume, synthetic detail and methods of application of the most important classes, information which will be invaluable to both student and research chemist alike. |
| chemistry of hair dye: No More Dirty Looks Siobhan O'Connor, Alexandra Spunt, 2010-07-13 It started with a harmless quest for perfect wash-and-go hair. Every girl wants it, and Siobhan O'Connor and Alexandra Spunt finally found it in a fancy salon treatment. They were thrilled -- until they discovered that the magic ingredient was formaldehyde. Shocked, O'Connor and Spunt left no bottle unturned. If it went on their body (and thus, was absorbed into their skin and bloodstream), they researched it. As it turns out, many of those unpronounceable ingredients in your self-tanner and leave-in conditioner are not regulated and the natural on your face wash doesn't mean what you think it does. Now, with the help of top scientists, dermatologists, and makeup artists, the authors share their compelling findings and the easy way to detoxify your beauty regimen. No More Dirty Looks also reveals the safest, most effective products on the market and time-tested home recipes.

| chemistry of hair dye: Dyes and Pigments Raffaello Papadakis, 2021-07-21 Dyes and pigments have been utilized since ancient times. They play an important role in everyday life and their use is interwoven with human culture. Even though numerous dyes and pigments have been synthesized to date, and a lot of knowledge has been gained regarding their production and properties, scientific research is pushing the boundaries towards novel dyes and pigments for high-tech applications. At the same time, the accumulation of dyes and pigments in natural environments and pollution of water resources due to their massive use are important consequences to consider. New methods for the degradation and removal of dyes and pigments from affected areas are highly sought after. As such, this book examines new trends in smart and functional dyes and pigments and their uses as well as novel treatment approaches to dye and pigment waste. |

| chemistry of hair dye: Dyes and Pigments Ahmet Gürses, Metin Açıkyıldız, Kübra Güneş, M. Sadi Gürses, 2016-05-04 In this book the authors go back to basics to describe the structural differences between dyes and pigments, their mechanisms of action, properties and applications. They set the scene by explaining the reasons behind these differences and show how dyes are predominately organic compounds that dissolve or react with substrates, whereas pigments are (predominantly) finely ground inorganic substances that are insoluble and therefore have a different mode of coloring. They also describe the role of functional groups and their effect on dyeing ability, contrasting this with the way in which pigments cause surface reflection (or light absorption) depending on their chemical and crystalline structure and relative particle size. The book explores the environmental impact of dyes in a section that covers the physical, chemical, toxicological, and ecological properties of dyes and how these are used to assess their effect on the environment and to estimate whether a given product presents a potential hazard. Lastly, it assesses how, in addition to their traditional uses in the textile, leather, paper, paint and varnish industries, dyes and pigments are indispensable in other fields such as microelectronics, medical diagnostics, and in information recording techniques. |
| chemistry of hair dye: Beyond Soap Sandy Skotnicki, Christopher Shulgan, 2018-05-15 In this surprising and remarkably practical book, Dr. Skotnicki reveals the harmful effects of modern skincare habits and provides a step-by-step guide to preserve the microbiome, fight aging and develop beautiful, problem-free skin. Women, men and children are having more skin problems today than ever before. Sensitive skin prevalence has skyrocketed, and the number of people reacting to cosmetics is climbing. Why? Dermatologist Sandy Skotnicki argues that the cause is a key element of our contemporary lifestyle: the grooming and beauty habits that the advertising and personal-care product industries have encouraged us to pursue. Those miraculous cleansers, creams and balms we're buying to protect our outer layer may actually end up harming the body's largest organ. In Beyond Soap, Dr. Skotnicki argues that the best state for normal skin is the natural state—the one that avoids disturbing the skin's protective barrier and the bacteria that accompanied the body throughout its evolution. A combination of diagnosis and prescription, Dr. Skotnicki explains the problem with society's current cleansing and beauty habits, then provides a practical guide on how to fix things with a 3-step product-elimination diet that will help you remove unnecessary and potentially harmful ingredients from your beauty and skincare regime, returning the skin to the condition nature intended. Beyond Soap also includes indispensable advice on how to wash and care for the skin of adults, babies and children, followed by a common-sense beauty regimen intended to stave off aging, reduce skin problems and return the face and body to its natural glow. |

| chemistry of hair dye: Vitiligo and Other Hypomelanoses of Hair and Skin Jean-Paul Ortonne, 2012-12-06 Leukoderma is a generic term for any pigmentary dilution, be it congenital or acquired, circumscribed or generalized, devoid of or partially lacking in pig mentation. In the approach to the diagnosis of leukoderma, we have generally first considered the age of onset, whether leukoderma was congenital or ac quired, the extent and pattern of involvement, and the degree of pigmentary dilution. The organization of this monograph reflects this approach. For ex ample, we have separated the section devoted to various disease entities into diffuse and circumscribed leukoderma and the latter into various etiologies such as genetic, metabolic, infectious, and endocrinologic. One of several justifications for this monograph is to present an approach to the diagnosis of leukoderma, as detailed in Part II. In formulating a guide for the physician, we have found some limitations to our previous approach; we therefore offer the following new classification based upon a clini cal-pathologic correlation. This could provide the means to describe both the clinical and pathologic findings in one term. |
