“…To perform spectroscopic analyses, locks of hair of about 20 cm length and 0.5 cm diameter were used. The average diameter of a single fibre was 70 ± 1 nm, 95% confidence limit (determined microscopically using 20 specimens) …”

“…Recently, we have reported an investigation on the semipermanent hair straightening focusing our attention on the chemical reactions that can occur between glyoxylic acid and some amino acids chosen as model compounds, whereas the modifications on the yak fibres have been analysed after the usual straightening procedure steps . Yak hair is commonly used to make wigs and has been extensively used as model for human hair in studies on hair treatment and dyeing . Actually, a recent comparative study on the structure and performance of Tianzhu white yak dress hair, tail hair and human hair has confirmed the structural similarity between white yak and human hair…”

Raman and IR spectroscopy were used to investigate the changes induced in yak hair keratin by the straightening treatment based on glyoxylic acid. The amino acidic residues that appeared involved in the reaction with glyoxylic acid were serine and lysine; the involvement of the latter was deduced by the spectroscopic detection of iminic species, resulting from the reaction between the aminic group of lysine and the carbonyl group of glyoxylic acid. The reaction with glyoxylic acid induced conformational rearrangements that mainly involved the fibre bulk rather than the cuticle. Changes in the average tyrosine environment and its hydrogen-bonding state were detected: at increasing glyoxylic acid incorporation, the tyrosine residues appeared more exposed, probably because of H-bond interactions with the COOH group. The distribution of the disulfide bridge conformation was also affected, although no cleavage of the S-S bond was detected, in agreement with the shiny and healthy appearance of the fibres.

“…Generally, large colorant molecules with an acidic nature dye hair by this mechanism. Semi-permanent hair dyes with smaller acidic molecules permeate or diffuse onto the cuticle and some parts of the cortex of the hair shaft by Vander Waals forces and partially ionic bonds [11,12]. Thus, hair coloring product design can enhance the color staining efficacy of the natural colorant extract from temporary to a semi-permanent hair dye.…”

“…On the other hand, the permanent dyes penetrate and diffuse deeper into hair shaft than the temporary and semi-permanent hair dyes. Later, oxidization and polymerization of the colorant molecules in the hair cortex result in coloring on the hair [11,12]. Accordingly, oxidation dyes have better hair coloring abilities than natural hair dyes [12], but there are issues that have been reported concerning the safety of synthetic hair dyes.…”

Background: Black bean is one of the important beans as the second most consumed bean globally after soybean. It has been reported as a sustainable source of anthocyanins, important natural colorants used in food and consumer products. However, industrial uses of black bean anthocyanins in pharmaceutics and cosmetics have rarely been explored. Thus, here, a black bean anthocyanin extract was prepared, quality controlled and developed into an efficient hair coloring product. Results: Black bean was macerated in hydrochloric ethanol to produce a dark-reddish 1.85 ± 0.04% dry extract with total anthocyanin content (TAC) of 1.24 ± 0.48 µg/ml cyanidin-3-glucoside. The extract was readily dissolved in propylene glycol (25%), giving a reddish to red-brownish solution at pH of 4.00-7.00. The addition of antioxidant significantly (p = 0.000) enhanced the stability of the extract in an accelerated stability test (90.34 ± 5.32 from 67.83 ± 3.45% TAC remaining). Three base hair gels containing different thickeners were developed to yield clear gels with a viscosity of 101,666.67-447,333.33 cps and a pH of 4.80-4.97. The gel base with the best hair application properties was chosen to mix with 8, 10 and 12% black bean extract to produce similar visually assessed red-brown gels (L* = 33.25-33.76, a* = 0.06-0.09, b* = − 0.45-0.38 and h* = 277.54-283.31) at 73,733.33-99,666.67 cps and a pH of 5.00-5.01. All of the black bean hair coloring gels were stable under the accelerated test. The 10% hair gel was tested for its hair staining efficacy. The black bean hair coloring gel was found to efficiently color hair, and the color was maintained through four washings. Conclusions: An alternative application approach of using black bean as a natural colorant is presented here, including its basic requirements for preparation and quality control from an industrial aspect. The efficient semi-permanent hair coloring product containing black bean is an innovative natural product and is considered as one progress towards a sustainable bio-based economy using a readily available industrial crop, black bean.

“…In general, the nitro anilines are not soluble in water and require a glycol or glycol derivative, such as glycerin, to be solubilized in the formulation. Specific solvents, such as mixtures of quaternary salts of high molecular weight, such as Quaternium-80, benzyl alcohol, and glycols are used to ensure not only their solubility in the formulation but also during application and product storage [24,27].…”

Types of Hair Dye and Their Mechanisms of Action

Hair color change by dye application is a common procedure among women. Hair dyes are classified, according to color resistance, into temporary, semipermanent, demipermanent and permanent. The first two are based on molecules which are already colored. Temporary dyes act through dye deposition on cuticles, but semipermanent may penetrate a little into the cortex and so the color resists up to six washes. Demipermanent and permanent dyes are based on color precursors, called oxidation dyes, and the final shade is developed by their interactions with an oxidizing agent, but they differ from the alkalizing agent used. In oxidation systems, there is an intense diffusion of the molecules into the cortex, what promotes a longer color resistance. Dyes and color precursors present differences related to chromophore groups, hair fiber affinity, water solubility, and photo stability. The aim of this review is to discuss the differences among hair dye products available in the market and their action mechanisms, molecular structures, application methods, and some aspects of formulations.
