This study examined the effect of Jojoba oil on the protection of virgin black hair and hair damaged by bleaching. Both hair types were treated for 35 days with 100% Jojoba oil or one of two types of hair conditioner, one formulated with 3% of Jojoba oil and the other formulated without Jojoba oil. The effect of protection was examined in terms of the change in the color, tensile stress, weight, and amount of protein leak compared to untreated black hair or bleached hair. The composition of fatty acids in the Jojoba oil was analyzed using the Gas chromatography mass spectrometry. The differences among the three treatments were statistically tested by one-way analysis of variance test and the Duncan post-hoc test at α = .05. The main fatty acid contained in the Jojoba oil was 11-eicosenoic acid (75.14%). Based on the statistical test it was found that 100% Jojoba oil was the most effective in increasing the tensile stress of black hair and the weight of bleached hair after 35 days of treatment.

We investigated the burning process of the virgin hair and straight permed hair using thermal analyser and scanning electron microscopy. After the thermal analysis, we found that weight started to change from $100^{\circ}C$. Whereas straight permed hair has weight decrease rate of 2.6% higher than the virgin hair till $200^{\circ}C$, those were 64.9% and 64.4% for the virgin and straight permed hairs, respectively at $300^{\circ}C$. At $400^{\circ}C$, the weight decrease rate of the virgin hair became lower than the other; they were 32.3% and 33.4% for the virgin and straight permed hairs, respectively. Final values were 25.4% and 28.3% at $500^{\circ}C$, which showed that final weight of burnt straight permed hair was higher than the virgin hair by about 2.9%. In terms of morphological changes, the hair started to melt together with adjacent ones by burning till $300^{\circ}C$. The medulla and cortex were melt and the inside was empty like bamboo. The hair burnt till $500^{\circ}C$ was entirely carbonized and found as a clod. We found many blowholes at the surface of the hair clump.

In the social atmosphere where the importance of appearance is increasing day by day, efforts and desires of modern people are becoming more active and diversified, and the beauty beauty industry is gradually becoming more specialized and specialized due to these effects. Hair damage is inevitable due to the excessive permanent wave or hair coloring of modern people. However, as the hair is damaged, the cuticle peels off and falls off, and the tensile force decreases and the satisfaction after hair styling or perm decreases relatively. Therefore, it is necessary to manage damaged hair, but since artificial synthetic products occupy most of hair treatment agents on the market, it is necessary to develop a hair treatment product containing antioxidants useful for the human body. In this study, the effect of maple leaf extract on the mechanical change of colored hair was analyzed to investigate the potential of maple leaf extract as a hair treatment agent to improve damaged hair and improve hair health. It is considered that this study will be used as basic data for the development of hair beauty products using natural products in the future.

Super engineering plastic(SEP) are applied to high performance and high value industries due to their excellent mechanical properties and high continuous operating temperature. Among them, PES and PEI are amorphous SEPs, and have the advantages of high flexibility, mechanical properties, transparency, and thermal stability. In this study, polyethersulfone(PES) and polyetherimide(PEI) fibers were manufactured to produce flame retardant artificial hair. PES and PEI fibers prepared through a melt-spinning process at a high temperature of 360 to 420℃. They are compared with commercial artificial hair by thermal gravimetric analysis(TGA), linear density, tenacity, and limited oxygen index(LOI) analysis. PES and PEI fibers have similar linear density and tenacity to commercial artificial hair, while their thermal stability and flame retardant are excellent. In particular, flame retardant was analyzed through LOI value and PES was 35.1%, which is superior to commercial artificial hair PET/Br(28.2%) and PET/P(20.2%). Therefore, PES and PEI are suitable as artificial hair for flame retardant.

Due to the fact that blood gathering is not readily accepted by people, it has been difficult to make a full-scale study on zinc through blood analysis. For that reason, in this paper, a correlation of zinc contents in serum and hair was studied to find out whether only hair, which is relatively easy to collect, can be used for a measurement of zinc content. The subjects were 47 healthy female collegians selected at random whose average age was 22, mean height 159.1cm and average weight 49.7kg. The mean zinc value in serum of subjects was ${107.1}\pm{29.0}{\mu}g{/100ml}$, while the mean value in hair was ${150.2}\pm{42.7}ppm$. Correlation analysis shows that there was a significant correlation in zinc contents of serum and hair ( p<0.01). The results shows that measuring zinc level by using only hair samples would be satisfactory. But the use of hair sample for a measurement of zinc level has one demerit. That is, the method is more likely to be subjected to contamination because it makes more complicated procedures in sample preparation than the method of using blood sample.

The purpose of this study is to classify and recreate the grooming styles of facial hair sported by noblemen during the Joseon Dynasty. Using existent portraits painted during this period as corroborative materials, this study has identified the traditional grooming styles of facial hair sought by noblemen in this age. This study has utilized 30 facial hair styles found in the portraits of noblemen inherited from the Joseon Dynasty, which take up the majority of the portraits currently remaining in Korea. To recreate grooming styles of facial hair, this study has divided facial hair into three types according to its location: beards, moustaches and whiskers. Based on the analysis of these divided grooming styles, this study has recreated grooming styles of facial hair by using artificial modelling heads, artificial hair, artificial glue, scissors, and a comb. The grooming styles of facial hair recreated by this study are closest to those that noblemen sought and did wear during the Joseon Dynasty. The results of this study are as follows. First, they groomed their moustaches in the 八 shape. Next, they wore their beards in the shape of an inverted triangle. Finally, they also grew and groomed whiskers. Though there are individual differences in the location, length, and volume of facial hair, noblemen in the Joseon Dynasty generally sought to wear their facial hair neat and long. Little research has been done to recreate and present noblemen's grooming styles of facial hair focusing on portraits. Thus, the findings of this study are expected to be utilized as basic materials for the education and research of grooming styles of facial hair according to ages. They can also be used as basic materials for recreating facial hair in historical dramas.
