  • This study comparatively analyzed hair bleaching and degree of damage by the temperature of a heating tool after coloring hair with a permanent, semi-permanent or plant hair dye. According to analysis by spectrophotometer, 'semi-permanent hair dye' was the highest, followed by 'permanent hair dye' and 'plant hair dye' in terms of changes in $L^*$ values. In terms of changes in hair shape when analyzed using FE-SEM, 'semi-permanent hair dye($150^{\circ}C$ or lower)' was the greatest, followed by 'plant hair dye($180^{\circ}C$ or lower)' and 'permanent hair dye($200^{\circ}C$ or lower)'. Therefore, it is reasonable to flat iron hair at low temperature. According to the test, amino acid values gradually decreased in both bleached and colored hair. The results obtained through TGA-based thermal analysis confirmed that as brightness increases, hair moisture contents decrease. This study aimed to protect hair by suggesting a correct use of a flat iron by the hair dye type during hair coloring. It appears that the study results would help hairdressers minimize hair damage by using a hair dye at proper temperature.

  • These days hair perm and dye is a modern trend that women prefer to create their own image and personality. However, chemicals for hair perm and dye are easy to damage hair. This study, then, is to find out some effective skills to minimize hair damage when hair perm and dye is done in a same time. The subjects were 200 hairs picked from five healthy women in their twenties which have not been permed and dyed since one year and more ago. The experimental group was divided into two groups: 1)the perm- nutritional treatment- dye (PNT) group 2)the dye- perm- nutritional treatment(DPN) group. After experiments, the states of "hair scale", "hair damage", and "color tone in dyed hair" were compared between two groups. The results are as follows: to lessen hair damage when hair perm and dye is done in a same time, nutritional treatments must be necessarily used on hair. To make hair colored more clearly when hair dye is done, it is more desirable to use nutritional treatments on hair.

  • This study intends to find out possible variations in physical properties and color of hair depending on dye type(acidic and alkalic) and permanent treatment/hair dyeing procedure. To meet the goals, healthy hair samples were taken from 5 women's hair speciment in 20's without experiencing in any harmful substance via long-term medications. and beauty care using chemicals. To get possible findings depending upon hair dye type and treatment procedure, both acidic and alkalic hair dye were applied on some specimens after permanent treatment, while on other specimens before permanent treatment. In order to determine scale damage, this study used SEM(Hitachi S-2500C) both hair thickness and tensile strength were measured with optical microscope(Nikon, MM-60/L3T) and Instron (4482-standard). Wave configuration was measured transverse and longitudinal round diameter. The chromaticity of each specimen was measured using a spectrocolorimeter(Color Techno System, JP/JX-777) with visual $C/2^{\circ}$ (at $2^{\circ}$ with C light source) monitor fixed to determine Lab and CMYK values. As a result, it was found that hair specimens were more significantly damaged with alkalic hair dye treatment than with acidic hair dye treatment, while hair specimens were more effectively dyed with the former hair dye type than with the latter one. For possible results depending on treatment procedure, it was found that hair specimens were less damaged but more effectively dyed with permanent treatment followed by hair dyeing than vice versa. Therefore, it was concluded that permanent treatment followed by acidic hair dyeing would be more effective in reducing hair damages.

  • The objective of this study is to investigate the efficacy of pomegranate hull colorant as a natural hair coloring dye. The extract of pomegranate hull was concentrated and freeze-dried to get colorant powder. Effect of dyeing condition and mordanting on the dye uptake of hair by using Al, Fe, Cu, Cr, Sn compounds, color change and colorfastness were explored. In addition, tensile strength was measured and the surface of the hair was observed. Dye uptake of hair measured by K/S value (400 nm) indicated that ionic bonding seems to be involved in the sorption of pomegranate colorant to hair. Maximum sorption was obtained at pH 3.5 and the concentration of 50% (on the weight of hair, o.w.h.). Acidic dyeing condition (pH $3.5{\sim}5.0$) showed yellow color however alkaline dyeing condition (pH $7{\sim}11$) gave reddish yellow color. Pomegranate hull colorant produced greyish brown color on hair and the hair mordanted with Fe showed dark brown color. Mordants except Fe did not increase dye uptake significantly. Mordants except Cu increased light fastness and mordants except Cr increased washing fastness level slightly. According to SEM observation and the tensile strength retention measurement, the mordant dyed hair gave more damage to hair by ultraviolet light and washing than the hair dyed without mordanting. Experimental results of K/S value and colorfastness(light and washing) supported that pomegranate hull colorant without mordanting can be used as a semi-permanent natural hair coloring dye.

  • The purpose of this study is to investigate the efficacy of juglone, which shows hish affinity to wool, for hair dyeing as a natural dye. Before dyeing hair with juglone, virgin hair was bleached by a conventional method using hair shops in the city. In order to study the dyeing properties of juglone on hair, the effects of dyeing conditions on dye uptake, color, tensile strength, and morphology were investigated. And the effect of Fe-mordanting on color change was also investigated. Dye uptake changed marginally as dye concentration increased in the range of 0.02-0.04g. Dye uptake increased progressively is dyeing time increased in the range of 10-20 min. Juglone produced YR colors on hair and the color of dyed hair got duller as juglone concentration increased. The hair was little damaged by bleaching, but cuticles were melted and stripped away by dyeing for longer time. Tensile strength retention decreased up to 65% at 20 min dyeing. Simultaneous mordanting with Fe did not improved dye uptake, but led to darker brown color compared with unmordanted hair.

  • The purpose of this study is to investigate the efficacy of safflower yellow colorant as a natural dye for hair coloring. The dyeing properties of safflower yellow colorant on hair were explored to obtain optimum conditions. Also, the effect of mordant was studied in terms of dye uptake, colorfastness, and hair damage to better understand the characteristics of the colorant. Tensile strength measurement and SEM analysis were carried out for investigating hair damage to light exposure and washing. On the basis of obtained results considering possible hair damage, optimum dyeing conditions were set 100%(o.w.h.) colorant concentration, pH 5, $40^{\circ}C$, and 20min. Dye uptake was improved more effectively by repeated dyeing rather than by increasing concentration. Pre-mordanting method improved dye uptake slightly, irrespective of mordant type. The safflower yellow colorant produced Y colors on hair. Cu and Fe mordants improved washing and light fastness slightly. Better strength retention was obtained with the mordanted-dyed hair than the unmordanted-dyed hair after light irradiation for 40 hours and 10 repeated washing. The hair was more damaged by light exposure than by washing. It was concluded that the safflower yellow colorant can be used as a natural semi-permanent hair dye producing Y color without mordanting.

  • Greying of hairs or Canities (Sheeb) is a hair disorder characterized by premature graying of scalp hair, beard, moustache etc. In Unani system of medicine (USM), the causes of premature greying of hairs, concept behind graying of hairs, principles of treatment, preparations that prevent premature greying of hairs, regimen, systemic and local treatment to stimulate pigmentation and the most interesting point is the use of different type of hair dyes (khizabat) is all illustrated. Classical texts described black, red, blond and white hair dye preparations with formulae and method of use. Initially for the hair graying management, utilizing simple and complex substances from plants, minerals, metals and mixture of these was the main method, which satisfied the desire to change the colour of the hair. With the advancement in chemical science, dyes formulaes, method of formation and application are changed. But due to the awareness about demerits of chemical dyes, people are looking back towards the natural ways to combat hair greying and herbal hair dye is an alternative. This paper is an overview of Unani drugs of local and internal use for hair greying with special attention towards herbal dyes. Most commonly used herbs in khizaab with their actions and constituents has been summarized. This is an effort to globalize the benefits of Unani herbs in hair greying problem. In short, International demand for hair dyes has been steadily growing and there is a wide scope for exploring different aspects of hair greying treatment and dyes in USM.

  • Human hair is a kind of fibrous keratin which has much cystine residues like wool fiber. It protects human head from the dangerous shock and is an organ to release heavy metals in human body. Recently, in many dyeing field there is a trend to utilize the natural dyes. Cochineal is a reddish natural mordant dye. When the cochineal is applied in human hair dyeing, it is expected that dyeing rate will be slow and wash fastness will be poor on account of large molecular weight relative to oxidative dyes. In this work, we investigated the effects of tributyl phosphate in hair dyeing with natural dye cochineal. Dyeability of hair increased significantly by adding tributyl phosphate in cochineal dyeing. Nevertheless the hair was slightly damaged during dyeing, the dyed hair showed a good wash fastness.

  • Dyeing properties of the colorants extracted from pomegranate hull on hair were investigated to study its efficay of natural hair coloring dye. Effect of dyeing condition and mordanting on dye uptake, color change and colorfastness were explored. In addition, tensile strength retention is measured and the surface of the hair was observed by SEM. The water extracted pomegranate hull was concentrated and freeze-dried for preparing colorant powders. It was considered that ionic bonding was involved in the adsorption of pomegranate colorants to hair. Pomegranate hull colorants produced greyish brown colors on hair and the hair mordanted with Fe showed dark brown color. Mordant except Fe did not significantly increased dye uptake. Mordant except Cu increased light fastness, mordant except Cr increased washing fastness. SEM to observe the hair is damaged by ultraviolet light and cleaning. This is consistent with the results of tensile strength retention. From the results of colorfastness th washing and light, it was concluded that colorants from pomegranate hull can be need as a semi-permanent natural hair coloring dye.
