Many Koreans have recently bleached their black hair to blond or a light color due to the influence of their favorite Korean idols. Bleaching effects were studied under various bleaching conditions, such as the concentration of oxidants, the ratio between bleach accelerant and oxidant, and treatment temperature and time. The degree of damage of bleached hair with the same color difference (${\Delta}E$) intervals was observed in SEM images, the retention of breaking load and the change of color after dyeing. The ratio between bleach accelerant and oxidant of 1:2.5 was an effective condition. $L^*$ values of the bleached hair treated with 9% oxidant increased to 90 min. At a treatment temperature of $30^{\circ}C$, $a^*$ values were maximum at 30 min and then decreased as time further increased; however, $b^*$ values of the bleached hair increased as the treatment time increased. At $45^{\circ}C$, both of $a^*$ and $b^*$ values showed a maximum at a specific time. Bleaching efficiency was influenced most by temperature, followed in order by time, and oxidant concentration. As the treatment time increased, $L^*$ values greatly increased with twice treatment; however, $a^*$ and $b^*$ values decreased. Bleached hair, which had a color difference of higher than 30, showed the scales were completely removed and the retention of the breaking load greatly decreased. Highly bleached hair showed a great decrease in $L^*$ values by dyeing; however, dyeing with bright colors was more indicative to the effect of bleaching.

Guanine nucleotide-binding protein subunit alpha-s ($Gn{\alpha}s$) is a small subunit of the G protein-couple signaling pathway, which is involved in the formation of coat color. The expression level and distribution of $Gn{\alpha}s$ were detected by quantitative real-time-polymerase chain reaction (qPCR), western blot, and immunohistochemistry to investigate the underlying mechanisms of coat color in white and black skin tissues of mice. qPCR and western blot results suggested that $Gn{\alpha}s$ was expressed at significantly higher levels in black mice compared with that of white mice, and transcripts and protein possessed the same expression in both colors. Immunohistochemistry demonstrated $Gn{\alpha}s$ staining in the root sheath and dermal papilla in hair follicle of mice skins. The results indicated that the $Gn{\alpha}s$ gene was expressed in both white and black skin tissues, and the expression level of $Gn{\alpha}s$ in the two types of color was different. Therefore, $Gn{\alpha}s$ may be involved in the coat color formation in mice.

In ancient times, hairstyle varies according to tribes. Because it is a social product that depends on status, class, and gender within the tribes, research on the hairstyle is an important source for studying the culture of the tribes. The purpose of this study is to analyze hairstyle of the Scythians and to understand the culture of the Scythians. Furthermore, the purpose is to identify the ethnic group based on this research. And it is intended to use the results as a comprehensive resource for research on the origins of Korean ancient costumes. As a research method, literature study and artifact analysis were performed concurrently. Data for artifact analysis were taken directly from the Eremitage Museum in St. Petersburg, Russia, where the researcher visited for this study. The conclusions of this study are as follows: Hairstyle of the Scythians were classified into three types: straight hair, braided hair, and tied hair depending on social status, age, and region. Straight hair was usually seen with kings, royalty, and warriors, and the hair length varied according to their status. Braid hair appears by a depiction of an old man and young Scythians. Tied hair was observed in the warrior. The beard was divided into chin-beard and mustache. Long chin-beards and mustaches were mostly observed in the ruling classes, while medium length chin-beards and short mustaches were considered the most common form of beard because they appeared in most classes. The young Scythians, regardless of their status, had no beard.

In the Edo period speaking of hair culture, common women wore decorative pigtail ribbons on the right, and twisted from side to side their tressed hair in such a manner as ungeunmeori and traemeori. Instead of gachae, common women used gogae made of their own hair, ungeunmeori on forehead, or jjokjinmeori at the back of head. During the Edo period, people women naturally exposed their necklines as a way of exposing their faces in the aesthetically ceremonial act of wearing make-up. As for lipsticks, they rouged extracts from red petals of safflowers mainly on their lips, and sometimes on their cheeks by blending this with white powder. Samurai families disliked women who wore thick lip makeup. In the latter period, women painted their necklines or foreheads black, applied a small amount of rouge on their cheeks thinly or thickly, and colored a reddish color into their fingernails by using petals and leaves of balsam flowers. Despite the chronological and spatial proximity of the King Jeongjo period and the Edo period, it was found that there were no similarities between two countries' cosmetic cultures. Moreover, it was discovered that current TV dramas were being produced, even not based on historical evidence in the Jeongjo period.

By such movement. people started to get interested in the environment and ecology. This then lead to the interest of the rights of the minority. With the youngs as the central figure A fro hair style and dashiki appeared as the street fashion. The characteristics of African costume applied to A fro fashion in 1990' s is as below. First. the North African style. Djellaba. and wrap style in the most common silhouette. Second. heavy materials such as stone. copper. silver. and gold are used. Necklace can be classified according to it's simple but. modern style. delicate but grand style. Bracelets are however. broad in width and many rings are worn widely. Third. Multi colored stripe and prints inspired by tattoo and deformation using red brown. dark beige. and orange are printed on textiles such as see through. Fourth. image of tattoo and deformation are applied to make-up. A fro hair and corn beads are also African taste. Fifth. African taste in recent fashion showed off the black beauty by appointing black models at the collection. In analyzing the study done above. characteristic images of African costume. accessaries and body painting was applied in presenting 3 creative designs. The first design named "Geometric I", took it's motif from the geometric pattern of the body painting with the afro hair. "Geometric II", the second design, showed it's application of geometric pattern of mutilation and the silhouette of the costume by using the see through. The third design called the "Geometric III" showed that the aesthetic and decorative side of clothing can be satisfied by applying various form and color of accessaries as the motif. A fro fashion is chosen as one of the folklore mood and it's beauty is conveyed on till today.
