Abstract:

Plant-based hair coloring is a natural hair coloring method, which allows to obtain a variety of colors and additionally nourishes the scalp and hair. The aim of the study was to present the knowledge on the available dyeing methods using plant materials and to investigate the color potential of particular herbs. Lawsonia inermis, Hibiscus sabdariffa, Rheum officinale, Sambucus nigra, and Chamomilla recutita were selected to the research. A video dermatoscope was used to demonstrate the influence of the coloring process on the structure, appearance of the cortex, areola, and the core of the hair. The natural method of dyeing hair is characterized by a lower allergenic potential as compared to the synthetic method. However, taking into account the color limitations of the selected plant materials, obtaining the effect of full coverage of the hair with color, is not always possible. It was shown that the selection of additives with an appropriate pH value allows to obtain favorable results.

Abstract:

Background: Hair coloring, or hair coloring, is the follow of fixing the hair color. The most reasons for this area unit cosmetic: to hide gray or white hair, to alter to a color thought to be additional modern or fascinating, or to revive the initial hair color once, it's been stained by hairdressing process or sun bleaching. Hair coloring is often done professionally by a stylist or severally reception. Celtic folks colored their hair blonde; they bleach it by laundry them in lime and brushing it back from their foreheads. The coloring of hair is associate ancient art that involves treatment of the hair with varied chemical compounds. In history, the dyes were obtained from plants. The event of artificial dyes for hair is derived from the legendary discovery of the reactivity of para-phenylenediamine (PPD) with air. Results: Hair dyes are cosmetic compounds that make contact with the skin throughout application. As a result of this skin contact, there exists some health risk related to use of hair dyes. People allergic to protein as an example, can have to be compelled to take care once buying hair color since bound dye includes protein. Protein doesn't have to be compelled to be eaten for it to cause associate hypersensitivity reaction. Skin contact with protein might cause a reaction; thus, resulting in associate hypersensitivity reaction. Symptoms of those reactions will embody redness, sores, itching, burning sensation, and discomfort. Symptoms can typically not be apparent instantly following the appliance and process of the tint, however may arise once hours or maybe daily later. Conclusion: Pigments of the hair got colored by the tactic of removing, replacing, or covering up. Employment of those chemicals may cause varied adverse effects, at the facet of temporary skin irritation and hypersensitivity, hair breakage, skin discoloration, and explosive hair color results. The ultimate color of every strand of hair can depend upon its original color and body. As a result of hair's color and body across the pinnacle and on the length of a hair strand, there'll be delicate variations in shade across the complete head. This provides an additional natural-looking result than the solid, everywhere color of a permanent color. Thus, hair dyes area unit regulated within the industrial marketplace and, as new toxicity knowledge is generated for a few hair dye, and health risks area unit discovered, in a controlled people, employment of hair coloring may end up in aversions and/or skin irritation.

Abstract:

Hair coloring is the act of changing the hair color, which has been known since the times of Egypt, Ancient Greece, Ancient China, and India. At that time, the colors used that came from plants were called vegetable dyes or traditional dyes, where the coloring was done to change the original hair color or to cover gray hair and follow the existing trends. Natural dyes are not only used as medicine but can also be used as cosmetic dyes. One of the natural ingredients that can be used to make hair dye preparations is the skin of red dragon fruit (Hylocereus Polyrhizus). In general, dragon fruit skin is rarely used properly, even thrown away when finished) It's just that many people don't know how to use it, thus increasing the amount of waste from dragon fruit skin.

Abstract:

There is an on-going demand in recent years for safer and “greener” hair coloring agents with the global consumer awareness of the adverse effects of synthetic hair dyes. The belief in sustainability and health benefits has focused the attention of the scientific community towards natural colorants that serve to replace their synthetic toxic counterparts. This review article encompasses the historical applications of a vast array of natural plant hair dyes and summarizes the possible coloration mechanisms (direct dyeing and mordant dyeing). Current information on phytochemicals (quinones, tannins, flavonoids, indigo, curcuminoids and carotenoids) used for hair dyeing are summarized, including their botanical sources, color chemistry and biological/toxicological activities. A particular focus is given on research into new natural hair dye sources along with eco-friendly, robust and cost-effective technologies for their processing and applications, such as the synthetic biology approach for colorant production, encapsulation techniques for stabilization and the development of inorganic nanocarriers. In addition, innovative in vitro approaches for the toxicological assessments of natural hair dye cosmetics are highlighted.

Abstract:

Yak belly hair was proposed as a cheap substitute for human hair for the development of hair dyes, as its chemical composition closely resembles human hair in Raman spectroscopy. The absence of melanin in yak belly hair also leads to a strong reduction of fluorescence in Raman measurements, which is advantageous for the investigation of the effectivity of hair dyes. To assess the suitability for replacing human hair, we analyzed similarities and differences of both hair types with a variety of methods: Raman spectroscopy, to obtain molecular information; small-angle X-ray scattering to determine the nanostructure, such as intermediate filament distance, distance of lipid layers and nanoporosity; optical and scanning electron microscopy of surfaces and cross sections to determine the porosity at the microstructural level; and density measurements and tensile tests to determine the macroscopic structure, macroporosity and mechanical properties. Both types of hair are similar on a molecular scale, but differ on other length scales: yak belly hair has a smaller intermediate filament distance on the nanoscale. Most striking is a higher porosity of yak belly hair on all hierarchical levels, and a lower Young’s modulus on the macroscale. In addition to the higher porosity, yak belly hair has fewer overlapping scales of keratin, which further eases the uptake of coloring. This makes, on the other hand, a comparison of coloring processes difficult, and limits the usefulness of yak belly hair as a substitute for human hair.

Abstract:

A new approach for hair treatment through coating with nanotubes loaded with drugs or dyes for coloring is suggested. This coating is produced by nanotube self-assembly, resulting in stable 2–3 µm thick layers. For medical treatment such formulations allow for sustained long-lasting drug delivery directly on the hair surface, also enhanced in the cuticle openings. For coloring, this process allows avoiding a direct hair contact with dye encased inside the clay nanotubes and provides a possibility to load water insoluble dyes from an organic solvent, store the formulation for a long time in dried form, and then apply to hair as an aqueous nanotube suspension. The described technique works with human and other mammal hairs and halloysite nanoclay coating is resilient against multiple shampoo washing. The most promising, halloysite tubule clay, is a biocompatible natural material which may be loaded with basic red, blue, and yellow dyes for optimized hair color, and also with drugs (e.g., antilice care-permethrin) to enhance the treatment efficiency with sustained release. This functionalized nanotube coating may have applications in human medical and beauty formulations, as well as veterinary applications.

Abstract:

Hati ungu contain natural dyes derived from anthocyanins. Anthocyanin is a pigment that is classified into flavonoids which in general gives a specific color to plants. The natural color found in this purple liver plant can be used as a natural coloring agent in cosmetics. Hair dye cream preparations were chosen because they are popular and easy to use. The purpose of this study is to determine ethanol extracts of hati ungu can be made as a preparation for hair dye creams, and which formula gives the best color. The research method was carried out including making ethanol extract of hati ungu (Tradescantia pallida) by maceration using 96% ethanol.The results of research on 4 hair dye cream formulations, preparations met the test requirements. The results of the basting test on hair with a vulnerable time for 1-4 hours showed that at the fourth hour the results of hair coloring give a good color. In the color stability test of washing, after washing with shampoo fifteen times all four formulas have a fixed color up to 9 times washing. The results of color stability to sunlight show that after the hair is exposed to sunlight the color looks slightly changed, hair color becomes darker than before. From the results of the research the concentration of ethanol extract of hati ungu which gives the best purple color is ethanol extract cream of hati ungu 20%.

Abstract:

The cosmetic market is rich in products that allow changing the color of hair. There are three options for chemical coloring, depending on the duration of the target color. Among them, there are short-term, semi-permanent, and long-term dyeing. Using synthetic ingredients, it is possible to obtain a full range of colors. Reports of undesirable side effects of chemical dyes on both the scalp and hair structure support a return to natural hair coloration and a development in this direction. The aim of the work was to draw attention to apply botanical raw materials in hair dyeing. The work presents the characteristics of the following plant materials used in hair dyeing: defenseless lawsonia, oxalic hibiscus, rhubarb, elderberry and chamomile.

Abstract:

Waardenburg syndrome (WS) is a group of rare genetic disorders characterized by hearing loss, changes in coloring of hair, skin, and eyes, and alterations in the shape of the face. Tietz syndrome is another rare disorder which presented similar phenotypes to WS. Patients with Tietz/Waardenburg syndrome often present with pale blue eyes, albino skin, and distinctive hair coloring, such as a patch of white hair or hair that prematurely turns gray. At present, more than six candidate genes are responsible for four types of Waardenburg syndrome and Tietz syndrome. This study is aimed at identifying the pathogenic gene variants in a three-generation Han Chinese family with hearing loss, blue-gray iris, albino skin, and white hair. In order to discover the molecular genetic lesion underlying the disease phenotype, whole exome sequencing in the proband, with Tietz/Waardenburg syndrome phenotypes, of a Han Chinese family from HeBei, China, was conducted. A novel heterozygous c.650G>C/p.Arg217Thr variant in melanocyte inducing transcription factor (MITF) was identified. Sanger sequencing further validated that this mutation existed in three affected individuals and absent in healthy family members. Bioinformatics analysis predicted that this mutation was deleterious. Our study further identified the genetic lesion of the family. Simultaneously, our study may also contribute to genetic counseling, embryonic screening of in vitro fertilized embryos, and prenatal genetic diagnosis of patients with Tietz/Waardenburg syndrome, especially for the proband, unmarried and unpregnant women, to reduce familial transmission in this Han Chinese family.

Abstract:

Albinism is a hereditary disorder that causes decreased pigmentation (coloring) in the body. As a consequence, albinism individuals are mostly fair-skinned with light hair known as oculocutaneous albinism. Skin, hair and color of the eye may vary, however, as some people with albinism may have dark brown hair and green or hazel / blue eyes. In both cases, poor vision and varying degrees of nystagmus (uncontrolled side-to-side eye movements) are observed. Everyone with HPS has albinism but not all people with albinism have HPS. We recorded a case with multiple comorbidities of a 37-year-old female patient with Hermansky-Pudlak syndrome (HPS) here

Abstract:

Polygonum multiflorumRadix (PMR) has long history in hair growth promotion and hair coloring in clinical applications. However, several crucial problems in its clinic usage and mechanisms are still unsolved or lack scientific evidences. In this research, C57BL/6J mice were used to investigate hair growth promotion activity and possible mechanism of PMR andPolygonum multiflorumRadix Preparata (PMRP). Hair growth promotion activities were investigated by hair length, hair covered skin ratio, the number of follicles, and hair color. Regulation effects of several cytokines involved in the hair growth procedure were tested, such as fibroblast growth factor (FGF-7), Sonic Hedgehog (SHH),β-catenin, insulin-like growth factor-1 (IGF-1), and hepatocyte growth factor (HGF). Oral PMR groups had higher hair covered skin ratio (100 ± 0.00%) than oral PMRP groups (48%~88%). However, topical usage of PMRP had about 90% hair covered skin ratio. Both oral administration of PMR and topically given PMRP showed hair growth promotion activities. PMR was considered to be more suitable for oral administration, while PMRP showed greater effects in external use. The hair growth promotion effect of oral PMR was most probably mediated by the expression of FGF-7, while topical PMRP promoted hair growth by the stimulation of SHH expression.

Abstract:

High school cosmetology students study the methods and effects of various human hair treatments, including permanents, straightening, conditioning, coloring and cutting. Although they are provided with textbook examples of overtreatment and numerous hair disorders and diseases, a view of an individual hair at the high resolution offered by an SEM provides convincing evidence of the hair‘s altered structure. Magnifications up to 2000X provide dramatic differences in perspective. A good quality classroom optical microscope can be very informative at lower resolutions.Students in a cosmetology class are initially split into two groups. One group is taught basic controls on the SEM (focus, magnification, brightness, contrast, specimen X, Y, and Z axis movements). A healthy, untreated piece of hair is initially examined on the SEM The second group cements a piece of their own hair on a stub. The samples are dryed quickly using heat or vacuum while the groups trade places and activities.

Abstract:

HC Yellow No. 4 is a colorant for use mostly in hair dyes and colors, but also in a few hair tints. Concentrations at which the ingredient is used range from 0.1 % to 1.0%. Confusion has existed regarding the proper structure for this ingredient, but was resolved through additional analysis; the correct CAS number is 59820-43-8. Commercially available HC Yellow No. 4 may contain a nitroaniline impurity. Percutaneous absorption studies using commercial products containing 1% HC Yellow No. 4 found little absorption. Body weight decreases were noted in short-term oral toxicity studies and in a subchronic oral toxicity study. HC Yellow No. 4 did not produce irritation, sensitization, or photosensitization in animal tests (primarily using guinea pigs). In some feeding studies, fetal toxicity was observed, but no such effect was found in other feeding studies. HC Yellow No. 4 was mutagenic in several assays, but no evidence of carcinogenesis was found in oral or dermal studies. Two repeated insult patch tests, totalling over 200 human volunteers, found no sensitization reactions. While there was concern expressed over the reproduction and developmental toxicity found in feeding studies, such adverse responses would not be expected from the use of this ingredient in hair coloring products because so little HC Yellow No. 4 is absorbed. The presence of a low level of nitroaniline derivative impurity (0.3 to 7%) is not considered to present a human health risk because the products containing HC Yellow No. 4 are used in a brief and discontinuous manner, followed by rinsing. On the basis of the available data, therefore, it is concluded that HC Yellow No. 4 is safe as a hair colorant in the present practices of use.

Abstract:

Hair-coloring products include permanent, semi-permanent and temporary dyes that vary by chemical formulation and are distinguished mainly by how long they last. Domestic temporary hair dyes, such as fuchsin basic, basic red 2 and Victoria blue B, are especially popular because of their cheapness and facile applications. Despite numerous studies on the relationship between permanent hair dyes and disease, there are few studies addressing whether these domestic temporary hair dyes are associated with an increased cancer risk. Herein, to ascertain the bio-safety of these temporary hair dyes, we comparatively studied their percutaneous absorption, hemolytic effect and cytotoxic effects in this paper. Furthermore, to better understand the risk of these dyes after penetrating the skin, experimental and theoretical studies were carried out examining the interactions between the dyes and serum albumins as well as calf thymus (CT)-DNA. The results showed that these domestic temporary hair dyes are cytotoxic with regard to human red blood cells and NIH/3T3 cell lines, due to intense interactions with bovine serum albumin (BSA)/DNA. We conclude that the temporary hair dyes may have risk to human health, and those who use them should be aware of their potential toxic effects.
