“…For each condition, three swatches are tested. Shine: The shine of hair swatches was measured mid‐way along their length (approx. 12 cm) as described in a previously published technique using the SAMBA polarization – difference digital camera, based on a fast (up to 10 KHz) polarization analysis (SAMBA Model; Bossa Nova Technologies, Culver City, CA, USA). The choice of a polarized camera associated with a cylindrical support is used to measure the angular distribution from −45° to +45° (angle between the camera and the specular reflection) in a single measurement without moving the detection.…”

This work indicates that a very high amount (e.g. billions) of PM can be deposited on a full head of hair for subjects living in a severely aerially polluted environment. This process can be reproduced in vitro. In real-life, pollution has a strong impact on hair surface properties, leading to a modification of the visual aspect (loss of shine) and the alteration of hair surface (increase in friction force). This work may be used to pave the way for prevention and cleansing studies in the field of hair care.

“…In addition, the luster of hair of different colors is perceived differently by the human eye adding further complications. However, Lefaudeux et al [70] described a method for hair luster based on polarization imaging that they suggest is consistent for different hair colors.…”

“…Wool dyeing is very different from hair dyeing because of the high temperatures involved in the former. In fact, low temperature dyeing in wool is [80][81][82][83][84][85] C. Solvent assist dyeing permits wool to be dyed at [60][61][62][63][64][65][66][67][68][69][70] still too high a temperature for dyeing human hair. Prototype systems have been developed based on chemistry related to that of natural melanin pigment formation [10].…”

The different types of dyes described for human hair include, permanent or oxidation dyes, semipermanent dyes, temporary dyes or color rinses and other types of dyes either proposed for or used on human hair. The mechanism of oxidative dyeing of human hair is presented in detail describing a large number of different dye precursors and couplers and how they combine to form different dye species. Hydrogen peroxide and the new peroxymonocarbonate oxidative systems are presented. Different matrix compounds used in hair dyeing are also included. Regulatory activities related to oxidation hair dyes, described in this chapter, focus on the European community which has been the most active in the regulation of oxidation dye ingredients and provides periodic updates on the COLIPA website for safe and banned hair dye substances. Because of the increase in the aging population and the global sale of hair dye products to the graying population, a review of the initiation of hair graying including the age at which graying begins for different populations, the incidence of graying versus age in 5 year increments for different populations and graying among different geo-racial groups are also presented. IntroductionBecause of the increase in the aging population and the resultant graying of hair for all peoples of the world, the global sale of hair dye products has been increasing at a faster rate than many other hair care products. Therefore, a review of the incidence of hair graying, graying versus age and graying among different geo-racial groups is presented at the end of this chapter. Other areas of new research for this edition described in this chapter include a means to minimize hydroxyl radical in oxidative hair dyeing, a new oxidative system and photoprotection of hair proteins. Fading of artificial hair colors and effects of photofilters on fading, regulatory methods, hair shine effects and dyeing, and a novel method for producing permanent dyed hair using dye-metal ion complexes have also been included.

Other works [13,14] showed that the depth of shade depends mainly on the fiber denier, the inherent colours of the fiber, its surface and its geometry. These two papers were mostly based on experimental testing results and concluded that the depth of shade would be changed as the cross-section shapes varied. There was doubt that the mathematical relationship and index FI be universal and effective for other fibers with unique cross-section shapes. However, the variations of different NCCS fibers are innumerable, which means that the previous model and its alternative one should be reconstructed to match the real or quasiactual conditions of NCCS fibers, their yarns, and even fabrics. Polarization is a well known technique to carefully analyze the composition of the light scattered by an object [15-18]. If the illumination is polarized, the reflected and refracted light will remain polarized while the scattered light will be depolarized, and this fundamental property allows measuring independently the diffused and the reflected light.
