Journal of Photochemistry and Photobiology B: Biology, 2007
In general, human hair is claimed to turn yellower after sun exposure. This is particularly affirmed for white hair. However, quantitative data relating yellowness to hair type and to the radiation wavelength are missing. This work shows results of the effect of full or UVB-filtered radiation of a mercury vapor or a xenon-arc lamp on the yellowness of ...

Nanomechanical responses of human hair
Journal of the Mechanical Behavior of Biomedical Materials, 2016Here we report the first ever studies on nanomechanical properties e.g., nanohardness and Young׳s modulus for human hair of Indian origin. Three types of hair samples e.g., virgin hair samples (VH), bleached hair samples (BH) and Fe-tannin complex colour treated hair samples (FT) with the treatment by a proprietary hair care product are used in the ...

The primary reactions involved in permanent-waving, straightening (relaxing), and depilation of human hair begin with reduction of the disulfide bond. In permanent-waving and hair straightening, reduced hair is stressed, that is, curled or combed straight, while molecular reorientation takes place primarily through a disulfide—mercaptan interchange ...

The composition of amino acid residues in bleached hair and in hydroly-sates of oxidized keratin fibers is described in Chapter 2 and also in publications by Zahn [1,2], Robbins et al. [3–6], Maclaren et al. [7,8], and Alter and Bit-Alkis [9]. Although, several questions remain unanswered, especially with regard to the structures and reactions of hair ...

Clinics in Dermatology, 1988
Abstract The process of hair formation involves keratinization. Hair and its sheaths undergo keratinization at different speeds and with different modes. In the hair bulb, the matrix of hair and its follicle are composed of similar-looking immature cells, eg, they all contain a small number of wispy tonofilaments and weakly developed desmosomes ...

In the literature the term “hair” is applied not only to the pelage of mammals, but also to other structures such as bristles on insects, sensory organs in crustaceans and small structures on plants. The present discussion will be con-fined to the pelage of mammals.

There are three ways to modify the color of hair: it may be made lighter by bleaching (see Chapter 4); artificial colors may be added to the hair; or a combination of both of these methods may be employed. Adding color is the subject of this chapter.
