Cosmetic treatment

Based on these results, an application of materials based on purified BC, e.g., as NanoMasque , in the field of cosmetic treatment is possible.

Marques and colleagues also suggest the loss of drugs from the hair matrix due to cosmetic treatments. In studying the concentration of cocaine in the hair of mother/ infant pairs, they found that it was possible to increase the correlation between the amount of cocaine in the mother s hair and the infant s hair by eliminating... 

For forensic testing, achieving positive results free from the ambiguities of false positives due to external contamination is the most critical element in the analytical process. For medical testing there are two additional critical criteria. One of these is that the hair has not been rendered porous by cosmetic treatment, since this can lead... 

Beard hairs have the slowest growth rate (approximately 0.27 mm/d) and a long growth/rest cycle duration of 14-22 months/9-12 months. Beard hairs are exposed to sweat and sebum secretions, the latter being, on the contrary to scalp hairs, excreted through a duct that opens directly onto the surface of the skin. Like scalp hair, beard hair may be subject to environmental contamination and/or cosmetic treatments. In addition, when beard hair samples are obtained by shaving, they are likely to be contaminated by pieces of epidermis. Like scalp hair, beard hair follicles are of the male sexual type. 

Axillary and pubic hairs are quite similar in terms of growth rate (approximately 0.3 mm/d) and growth/rest cycle durations (11-18 months/12-17 months). They are both exposed to sweat and sebum secretions in addition to the secretions of the apocrine glands which are present only in the axilla and pubic area and discharge directly into the hair follicle rather than onto the surface of the surrounding skin. Axillary hair is less exposed to environmental contamination, but may be subjected to cosmetic treatments. Pubic hair may be contaminated by urine. Both types of hair are composed of ambosexual follicles. 

Botulinum toxin is both a medication and a neurotoxin, produced by the bacterium Clostridium botulinum. It is the most toxic protein known. It can be used to treat muscle spasms, and is sold commercially under various names (Botox, Dysport, Myobloc, etc.). Botox Cosmetic and Vistabel are available for cosmetic treatment. The toxin protein consists...

Many other hydroxy acids (and the related keto acids) are used in cosmetic treatments (Table 6.1).

The following factors can produce differences in whole-fiber amino acid analysis results genetics, weathering (primarily sunlight exposure), cosmetic treatment, experimental procedures, and diet (not normal diets of healthy individuals, but protein-deficient diets). 

These relationships are based on the fact that leucine and cystine are common components of the low-sulfur proteins and that proline and cystine are primary components of the high-sulfur proteins. They further suggest that the cystine content should be about 17 to 18% and that large variations beyond the calculated values for these three amino acids indicate some cause of variation such as genetic, environmental (sunlight exposure), cosmetic treatment, or diet. Variation from these factors is described later. 

No consistent relationship was found between age and cystine content. Although factors such as diet (malnutrition), cosmetic treatment, and environmental effects (sunlight degradation) may have contributed to variation among these samples, such factors were not considered in this study. 

Alterations to the fibers that affect the apparent frequency of acidic or basic groups, such as hydrolysis, susceptibility to hydrolysis, or the introduction of sulfonic acid groups [24, 66], can affect the acid- and/or basecombining capacity of hair. Therefore, permanent-waving and especially bleaching can affect these titration parameters [8]. The effects of cosmetic treatments and environment on these parameters are described in detail in Chapter 5. 

The dissolution or the removal of structural lipids or proteinaceous matter from hair-probably from the cell membrane complex or epicuticle by either shampoos, surfactant solutions, or other cosmetic treatments-has been demonstrated by several different scientists. For example, Marshall and Ley [153] demonstrated the extraction of proteinaceous components from the cuticle of wool fiber by surfactant solutions of sodium dodecyl sulfate, cetrimonium bromide, and triton X-100. Zahn and co-workers [154, 155] and Mahrle [156] independently showed that part of the lipid components of the cell membrane complex were removed from hair by permanent waving. 

The objective of these density experiments was not to determine the absolute density of human hair, which is elusive [88], but to determine the relative density of human hair and wool fiber and the influence of damaging cosmetic treatments on this important property. The results of these experiments confirm the conclusions of several others [75, 89] the densities of human hair and wool fiber are similar, and there is no appreciable change in the density of human hair from permanent-waving or bleaching treatments.

Note-. Fiber length is not considered, since it is not changed by cosmetic treatments. 

Because fiber length is not changed by cosmetic treatments, length is not relevant for the type of analysis that considers changes by cosmetic treatments. For flyaway hair manageability, any change that increases static... 

In this book, I have tried to provide a reasonably up to date and complete account of the chemical and physical properties and behavior of human hair. Chapter 1 describes the structure of human hair, from the microscopic level down to the molecular level. Chapter 2 discusses its chemical composition, and Chapters 3 through 7 emphasize the organic and physical chemistry of the reactions and interactions of hair with different cosmetic or potential cosmetic ingredients. The last chapter describes the physical behavior of hair before, during, and after cosmetic treatments.
