  • The tannin acid and the enzymes have been used in order to improve the ruggedness in laundry and the absorption of dyes and pigments in the textile industry for several years. The enzyme processing on the protein fiber minimizes the damage of the entire fiber and improves the dyeability by effectively modifying only the hydrophobic surface. This study tried out the structural observation by applying the Castanea crenata sieb. et. zucc. containing abundant tannin to the hair dyeing as the natural dyeing pigment along with Protease of Rhizopus sp. The dyeability was improved as compared to the dyeing using only the synthetic tanning and iron mordant. When the depth of pigment was higher in accordance with the surface observation, the enzyme dissolution had impact on dyeing and so the keratin layer on the hair surface. Accordingly, it was found that the appropriate depth was between 0.01 and 0.03%. It was estimated that 0.1% protease would treated within 30min. Consequently, it would cause the good reaction with the functional group of tannin pigment.

  • The use of protein-crosslinking enzyme, transglutaminase, as a biocatalyst in the processing of hair offers a variety of exciting and realistic possibilities which include improving the rigidity of hair fibers. Among the transglutaminases from many different living organisms, the microbial enzyme prepared from Streptomyces mobaraensis, significantly increased the tensile strength of hair by 15.64% compared to a control when it was applied to damaged hair. This indicates that transglutaminase can restore the negative effects of washing hair with shampoo. Also transglutaminase improved the characteristics of hair surface, which could be useful for increase of luster and reduction of friction force of hair surfaces.

  • 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.

  • Stained and discolored hair will be damaged by the shampooing, daily UV disposal, and the use of hair dryer. Thus many studies about the effect of various natural substances on the re-secure the skin and scalp are recently reported. This study was carried out to investigate the effect of green tea (Camelloia sinensis) seed oil on colored (dyed) and decolored (bleached) hair. The beneficial effects of green tea seed oil are already well known, but little research has been done about the hair treatment and fade-resistant effect. Dyed and bleached hair was pretreated with green tea seed oil to determine the tensile strength and elongation of the hair, to analyze the hair surface using SEM, and to compare the color fade using spectrocolormeter. The results showed that the tensile strength increased with green tea seed oil pretreatment samples for virgin, dyed, and bleached hairs. Elongation showed the reverse results showing the presence of hair treatment effect. The results of the surface pre-treatment in all groups analyzed by SEM, the hair cuticle became sharper, so coating effect were identified with all samples. The value of the $L^*$, $a^*$, $b^*$ decreased with washed hairs damaged by UV irradiation and the values were decreased also in dyed and bleached hair. In summary, green tea seed oil prevent reinjury to the heat and UV rays for colored and decolored hairs. Cosmetic practice effects of the oil were identified in the field to be appropriate to the customer's skin and scalp that natural cosmetic oils would like to offer.

  • The purpose of this study was to investigate the effects of home care hair treatment characteristics and frequency on hair during permanent wave treatment. The hair treatments distributed on the market were classified into cationic surfactants and silicone oil. Hair treatment was performed 5 times, 10 times, 20 times differently according to the frequency of use, and hair permanent wave was performed. The hair thickness, tensile strength, epidermal observation using SEM, and hair component analysis using EDS were performed as experimental methods. The results of the experiment showed that the natural-derived ingredient was the main ingredient, and the cationic surface activity and silicon oil-free product group had high hair protection effect. Therefore, the product group using natural ingredients should be further researched and developed, and the study on the method and frequency of use of products with irritant chemical ingredients should be conducted.

  • Hair luster is a key objective for consumers in the hair care market. Recently, as consumers using hair coloring or bleaching product increase, measurement and quantification of hair luster become more important. A hair visual appearance measurement system called SAMBA can quantitate the luster and effectively separate specular and diffuse light. SAMBA usually has been employed to measure, mainly with the change of shine value, effects of cosmetic treatments on hair shine and surface smothness. We conducted a study on the effect of dyeing and bleaching on the luster, as a result, a strong bleaching caused large decline of the luster. But the large decline of luster was caused by increasing intensity of diffusion and width of chroma peak, not the shine value. The system of dye toning for higher luster can be developed on reference to the peak type of chroma and diffusion depends on kinds and combination of dye.

  • Spectroscopic evaluation of hair chemical damage was performed by SEM/EDS, CLSM, and FT-IR spectroscopy. In SEM/EDS, hydrogen peroxide treated hair showed the loose packing of surface scales, lower ratio of sulfur element and higher ratio of oxygen atom. In the optical single section by using CLSM, high fluorescent intensity appeared in untreated hair. However, in case of treated hair, low fluorescent intensity appeared. This results the aromatic amino acids which can be autofluorescent were more abundant than bleached hair. FT-IR spectra showed that cysteic acid band intensity was increased by performing the bleaching treatments. These results indicate that the oxidative damage cleaves the S-S bond and results in the lower working force of hair fiber.

  • Onions are commonly available and easily processed, and since their skins are thrown away they could be very useful materials from the viewpoint of environmental preservation. This study aimed to process onion skins into the state of powder and look into the optimum condition for hair dyeing by decoloring virgin hair four times and observing the hair dyeing quality and its mechanical and morphologic changes by the different condition of onion skins in duration, temperature, density, pH, and mordant treatment. The observations of hair surface through scanning microscopy showed the formation of cuticle layer, though in a little blown-up state in the case of the hair dyed with onion skin application, when compared with bleaching hair with the completely dissolved cuticle layer. According to the above findings of experiments, the dyeing quality of the hair dyes with onion skin application was excellent, the dyeing was also feasible without mordants, and the use of Fe as the mordant increased dyeing exhaustion more, which would make it an effective hair dye. These results of the experiments indicate that the natural pigment extracted from onion skins can be actually used for hair dyeing from the viewpoints of the dyeing quality and the skin treatment.
