The purpose of this study is to compare hair care behaviors between Korean and Australian women whose individual hair characteristics, social backgrounds, and culture were different from each other. Then, this study also aims to provide some basic data for professionals in the field of beauty education and industry. Data were collected through a survey with 208 Australian females and 392 Korean females. Analyses included t-test, frequency analysis, and one-way ANOVA. The results are as follows: The Korean women mostly had black and brown natural hair, and 68.4% of them had color. On the other hand, the Australian surveyees had brown and dark blonde, and 85.4% of them had color. They both were asked why they were using hair products. The Koreans responded that they were for hair moisturization, while the Australians said they were for producing a hair style they wanted. In addition, the Koreans made the most use of a hair conditioner and hair wax, while the Australian women did a hair spray and gloss. As far as the satisfaction with beauty salon service goes, the Australian respondents showed more service satisfaction than the Koreans on average. The homogeneity of the two nations' average points was t-tested. The result indicated that significant differences existed in the hair shop satisfaction with services, such as dyeing, haircut, blow dry, shampooing and massaging, and staff attitudes.

To ascertain the effects of hair dyeing application on oxidative stress in human, a mixture of permanent black colored hair dye with the same amount of oxidant containing 6% hydrogen peroxide was used. A hair dyeing with contacting the scalp (conventional dyeing) and a hair dyeing with 3 to 4mm away from the scalp (alternative dyeing) were applied to each 15 young healthy women. Blood was taken from the brachial vein at two sampling times, just before and 6 hours alter the hair dyeing, and antioxidant enzyme activities and antioxidant contents were measured in red blood cells. After dyeing, malondialdehyde(MDA) contents for conventional dyeing group was shown to a tendence of more increased than alternative dyeing group. After dyeing, reduced glutathione (GSH) contents for conventional dyeing group was shown to a tendence of more decreased than alternative dyeing group. After dyeing, superoxide dismutase (SOD) and catalase (CAT) activities were significantly decreased in conventional dyeing group (p < 0.01), however, SOD and CAT activities were not significantly decreased in alternative dyeing group. After dyeing, there was no significant decrease in glutathione peroxidase (GPX) activity both for conventional dyeing group and alternative dyeing group. Therefore, after dyeing, the degree of oxidative stress in red blood cells for alternative dyeing group was appeared to be lower than conventional dyeing group.

Hair coloring before the 1980s was mostly to hide white hair by dying in black. With the introduction of color TV, however, the size of the coloring market has been expanding. Nowadays, artificial synthetic dyes are widely used, which, though advantageous in many points, have problems such as harmful effects on the human body, carcinogenesis, environmental contamination and damage on hair. On the contrary, natural vegetables obtained from Curcuma Longa L., A. catechu, polygonum indigo, henna, etc. are little harmful to hair or the skin of the head and cause few environmental problems. In addition, as they are natural materials collected from nature, they are considered positively by consumers. Thus the present study started from the necessity of research on the convenient use of environment?friendly and side-effect-free natural dyes, coloring technology for reproducing original color, the improvement of adhesion rate, etc. From the present research were obtained yellow color from Curcuma Longa L., brown from A. catechu, blue from polygonum indigo and orange from henna. It is expected that, based on materials from previous researches, there may be more researches on the use of natural dyes as hair colors.

Hair graying is processed by loss of melanin production caused by the decrease of activity and number of melanocyte and the accumulation of hydrogen peroxide ($H_2O_2$) in the hair follicle with increase of age. The purpose of this study was to investigate the effect the Black oryzasativa ethanolic extract (BLEE) on the melanin production. In this study BLEE at $8{\mu}g/ml$ or more showed a significant 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity and reduction power. BLEE at $16{\mu}g/ml$ or more showed promoted tyrosinase activity and melanin production. In addition BLEE scavenged intracellular $H_2O_2$ in 2',7'-dichlorodihydrofluorescein (DCF) fluorescence assay in B16F1 cells. However, Western blot analyses displayed that BLEE decreased the expression level of catalase, but no effect on the expression level of tyrosinase, tyrosinase associated protein-1 (TRP-1), tyrosinase associated protein-2 (TRP-2) and microphthalmia-associated transcription factor (MITF) transcription factor involved in melanogenesis. Thus, the promotive effect of BLEE on melanin production is attributed to the increase of tyrosinase activity and the reduction of intracellular $H_2O_2$ level. In conclusion, BLEE played a key role in in promoting melanin production, which suggests that the BLEE could be applied as a potential functional material in the development of hair care cosmetics related to the promotion of melanin production for the growth of black hair.

The results of the researches in the wig and the Boyo are as follows. The wig is to be classified into Bu, Pyun, Chah, Cheh, and kwik, Bu is an ornamental hairpin used by the empress, and it is decorated with Boyo. Pyun is a wig made of braided hair. Chah is made of Bal which is put together by its lenath, and it was also called Picheh or Pisuck. It is made, one by one, of hair of the convicts and the low-class people. 초도 has a meaning of toupee, and it is used to look beautiful with its thick black hair. Kwik is a wig made of hair as if it is weaved out of thread, and it is rounded with a wire. In ancient times, it was also called chah, Pi, or Pi People wore different wigs according to their class and the use, in order of Bu, Pyun, and Chah. There are remains of the Han Dynasty. Boyo, just like the wig, was originally a custom of the northern nomadic tribes which had been introduced to the later Han Dynasty. It is also called Cho Song and has a different meaning from the Boyo attached to a crown before the Han Dynasty. It became much more beautiful in the Which in period. Boyo gained its popularity by the women in Tang Dynasty, which is due to the influence by the customs of the western Ho tribe. The name of hairstyling using wigs in each period, and things such as hair, black thread, lignum, and paper were used as materials. Since the wig had differed according to the disparity in social standing it was prohibited to the general public, but it became in style later on. Wig also becomes popular in central Asia and gained its properity in the Tang Dynasty which is greatly influenced by the western countries. It is said in the records that the kobal Style had been exceedingly in fashion from the Ju to the Chung Dynasty, and the remains of the Han and Song Dynasty were found. times, it was also called chah, Pr, or period, and things such as hair, black thread, lignum, and paper were used as materials.

Objective: This study aimed to investigate the significant single nucleotide polymorphisms (SNPs) and genes associated with nine reproduction and morphological traits in three breed populations of Chinese goats. Methods: The genome-wide association of nine reproduction and morphological traits (litter size, nipple number, wattle, skin color, coat color, black dorsal line, beard, beard length, and hind leg hair) were analyzed in three Chinese native goat breeds (n = 336) using an Illumina Goat SNP50 Beadchip. Results: A total of 17 genome-wide or chromosome-wide significant SNPs associated with one reproduction trait (litter size) and six morphological traits (wattle, coat color, black dorsal line, beard, beard length, and hind leg hair) were identified in three Chinese native goat breeds, and the candidate genes were annotated. The significant SNPs and corresponding putative candidate genes for each trait are as follows: two SNPs located on chromosomes 6 (CSN3) and 24 (TCF4) for litter size trait; two SNPs located on chromosome 9 (KATNA1) and 1 (UBASH3A) for wattle trait; three SNPs located on chromosome 26 (SORCS3), 24 (DYM), and 20 (PDE4D) for coat color trait; two SNPs located on chromosome 18 (TCF25) and 15 (CLMP) for black dorsal line trait; four SNPs located on chromosome 8, 2 (PAX3), 5 (PIK3C2G), and 28 (PLA2G12B and OIT3) for beard trait; one SNP located on chromosome 18 (KCNG4) for beard length trait; three SNPs located on chromosome 17 (GLRB and GRIA2), 28 (PGBD5), and 4 for hind leg hair trait. In contrast, there were no SNPs identified for nipple number and skin color. Conclusion: The significant SNPs or genes identified in this study provided novel insights into the genetic mechanism underlying important reproduction and morphological traits of three local goat breeds in Southern China as well as further potential applications for breeding goats.

The aim of this study was to measure the hair melanins of various colors and to find the relationship between the quantity of melanins and hair color phenotypes in alpacas. According to the Munsell color system, 3 healthy alpacas were selected for each of the 22 different hair color phenotypes (66 alpacas altogether). Alpaca hair was taken from the lateral thoracic region and then dissolved with different solutions to obtain melanins. The values of alkali-soluble melanins (ASM), eumelanin (EM) and pheomelanin (PM) were measured by spectrophotometric assay, and labeled as Sp.ASM, Sp.EM and Sp.PM, respectively. Data were analyzed using SPSS11.5 software. Results showed that average Sp.ASM and Sp.PM were increased as the color deepened from white to black, ranging from 0.500 to 4.543 for Sp.ASM and from 0.268 to 1.457 for Sp.EM. However, average Sp.PM had no such apparent relationship with color. Based on the value of Sp.ASM and EM, 7 hues were produced and gray was a single hue. Most of the data were in a normal distribution (p>0.10). ANOVA analysis showed that mean values of Sp.ASM, Sp.EM and Sp.PM were significantly different (p<0.05). The results also showed that Sp.ASM was positively correlated with Sp.EM but the correlation between Sp.ASM and Sp.PM was not significantly different from 0. It is concluded that EM is the major constituent of alpaca hair melanin; there is a significant correlation among ASM, EM and alpaca hair colors, and EM is the most reliable parameter for distinguishing these groups.

This study was conducted to examine the effects and potential mechanisms of action of black soybean extracts and fermented black soybean extracts by Lactobacillus rhamnosus GG (LGG) and Bifidobacterium animals subsp. lactis BB-12 (BB-12) on proliferation of human follicle dermal papilla cells (HFDPC). We examined changes in pH, total polyphenol, sugar, and reducing sugar contents according to fermentation period of black soybean extracts. Assay using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide was performed to determine cell toxicity levels of the four black soybean extracts [black soybean water extract (BWE), black soybean ethanol extract (BEE), fermented BWE (F-BEW), and fermented BEE (F-BEE)]. Changes in mRNA expression levels of hair growth promoting factors and hair growth inhibiting factors by the four black soybean extracts were measured by real-time PCR. In addition, phosphorylation levels of mitogen-activated protein kinase family proteins were measured by western blot analysis. As a result, fermentation of black soybeans significantly reduced pH, total polyphenols, and sugar/reducing sugar contents. All four black soybean extracts showed no cellular toxicity in HFDPC. In fact, BEE significantly enhanced cell viability of HFDPC at $100{\mu}g/mL$ compared to control. BWE, BEE, and BWE-F significantly increased mRNA expression of vascular endothelial growth factor, and all four extracts increased mRNA expression of fibroblast growth factor. However, mRNA expression levels of apoptosis-related genes were not affected by black soybean extracts in HFDPC. Furthermore, BWE, BEE, and BWE-F significantly increased phosphorylation levels of extracellular signal-regulated kinase compared to control. Taken together, we demonstrated that black soybean extracts enhanced proliferation of human follicle dermal papilla cells partially via activation of hair growth promoting factors, although no particular significant effects on proliferation were observed by fermentation of black soybeans.
