In this study, hair care effects of the hair cosmetics including low molecular weight silk peptide, hydrolysate which is produced from cocoon were investigated. After producing the hair cosmetics including silk peptide which has 300-500 molecular weight, we measured its hair care effects through the various tests; change of the hair weight, hair thickness, absorbance rate and hair moisture value and micro structure analysis. As a result, S.P.T. (Silk peptide Treatment) was effectively penetrated into the hair which has been damaged by chemical treatments, increased the hair weight, thickness and hair moisture value and also recovered the cuticle of the hair. Thus, the treatment of hair with silk peptide hydrolysate would be effective to recover the damaged hair into the normal conditions.

Hair beauty treatments that can express individuality have increased and diversified. However, their repetitive use has also brought about hair damage. To reduce such damage, the importance of hair treatments when receiving chemotherapy has magnified greatly. In this study, the hair (normal hair, NH) of 5 people in their 20s has been collected and observed with SEM before dyeing (NH), after dyeing (DH) and after dyed and treated (DTH) to measure the hair's morphological damage and mineral content. SEM observation results revealed that, in DTH, a cuticle-like arrangement appears almost uniformly, the hair settles, the lines are smooth, and the damage degree is low. Regarding mineral content, the concentration of minerals was generally balanced. However, in the observation of toxic minerals and minerals found in large amounts, the concentration of Ba, Na, Ca, and Mg was higher than the balance range in NH, DH, and DTH.

This study collected 245 questionnaires from college students in Gyeonggi-do and analyzed them using SPSS statistical packages, with the aim of identifying the status of hair loss perception due to the relationship between stress and hair loss received by college students and analyzing the correlation between stress and hair loss perception by type. As a result of the study, it was analyzed that the biggest problem caused by hair loss was 'loss of confidence', and in particular, people who were stressed about career/employment and studies were analyzed to consider the problem of 'loss of confidence' the most serious. As a result of cross-analysis of the general characteristics of awareness and the 'most recent stress' item, and as a result of correlation analysis between stress by type and hair loss status that constitutes hair loss awareness, it was analyzed that all types of stress affect hair loss in college students. Among them, career/employment stress and academic stress were found to be the most influential stress, and in the event of hair loss, it was analyzed that they were more willing to engage in hair loss treatment for career/employment, study, and appearance before interpersonal relationships or economic problems. Therefore, this study is of great significance in that it classified stress by type and analyzed the correlation through empirical research methods by specifying the contents of hair loss recognition into three categories: hair loss status, hair loss management, and hair loss treatment.

The results of study for colorless hair manicure, which is well known for its useful point and supplement damaged hair glossy, luster, elastic and soft one are as follows. Hair protection effect by the management time of colorless hair manicure products, as below. When it comes to dyed hair group's hair surface condition. both level 3 and level 6 hairs cuticle changed to be irregular. And lose of cuticle has been observed with a fact that the space between cuticles are not clear. In case of manicuring, manicuring 2 weeks after dyeing is better complemented surface damage than manicuring right after dyeing. So, in case of making cuticle morphologic of good hair quality in manicuring dyed hair, it's more effective to manicure right after dyeing to both level 3 and level 6 hair.

Medical equipment of high frequency has been presently applied to various parts of human body and novel treatment effects have been shown by it. Recently there are many cases that high frequency apparatus has been used in dermatology as the interest in beauty has been growing. Especially used in skin, blood volume is increased by keeping surface temperature of skin at around $43^{\circ}C$ and domodex folliculorum are treated by applying high electric field. It is the aspect we consider that increasing blood volume and domodex folliculorum treatment take effect on hair loss. In this study, high frequency electrotherapy apparatus was proposed to be applied to hair loss treatment. For that, human body was experimented with varying output voltage and frequency. The adjustable switching signal for treatment was obtained from 100[kHz] to 1000[kHz] by using DSP. Stable output specific was also obtained by feedback control to protect human body. The best hair growth conditions were the output voltage of 1.2[kV], the frequency of near 300[kHz] and the maximum current of 2[mA]. We apply this high frequency electrotherapy apparatus to two bald men, 46-year-old and 45-year-old. After treatment for a month they had thick and strong hair.

Public interest in healthy hairs gets growing as damaged hairs are seen more frequently with the generalization of heat permanent waves. For this study, experiments have been conducted to understand the influences on the changes in physical and morphological features of wave forms and damaged hairs, by collecting virgin hairs from the women in their mid-20's, who had not experienced chemical applications, and by dividing the applications of heat perm hair treatments, PPT(for pre-treatment) and LPP(for post-treatment), into the pre-treatment, the post-treatment, the pre & post-treatment, and the non-treatment. For the wave formations, curl waves were investigated by the bare eyes using the pictures taken by a digital camera. For the comparison of physical features, the experiments of tensile strength and elongation were done and their mean values were found. For the observations of morphological features, the pictures were taken by SEM for comparison. As for the findings, regarding the curl wave shapes of hairs, the most even and elastic S curl was formed in the case of non-treatment. In the physical features, both of the tensile strength and elongation showed a decreasing tendency in line with the hair damage levels, and the case of the pre & post-treatment indicated the tendency most similar to the control group. In the morphological features of the cuticle, observed with an SEM, the pre-treatment showed the higher possibility of reducing the cuticle damages than the post-treatment did. LPP was found to play the role of protective membrane for the post-treatment, and the pre & post-treatment turned out to reduce most effectively the cuticle damages.

To protect healthy and beautiful hair, the hair protection effect was tested by adding an aloe extract from the hair solution. The treatment groups were grouped into four categories: Group II (Famma Treatment Only), Group III (Oxidase+aloe), Group IV (Reduce+aloe), and Group V (Oxidase+aloe, Release+aloe). The test hair is collected from women's hair in their 20s, 30s and 40s who have not undergone chemical treatment such as permanent and dying for one year and use 100% aloe stock solution. In order to evaluate hair thickness, cuticles, tensile strength, elongation and formation rate, the experiment environment was 28.9 degrees and 72% humidity. All statistical tests were done at 5% significant level. Cuticle, elongation, and formation rate were significantly improved (P<.05) and cuticle was best in group V, elongation was group III. In conclusion, aloe added to perm treatment were effective in improving cuticle, elongation rate, and formation of hair.

This case study describes the effect of Bojungikki-tang on chemotherapy-induced alopecia. Alopecia is a well-documented cause of distress to patients undergoing cancer treatment, but no approved pharmacological treatment exists for chemotherapy-induced hair loss. A 70-year-old female diagnosed with a cholangiocarcinoma and liver metastasis received chemotherapy, including gemcitabine and cisplatin, every three weeks. As a result of the continuous chemotherapy, she suffered various toxicity-related side effects, including bone marrow suppression, general weakness, nausea, peripheral numbness, and hair loss. Bojungikki-tang was initially administered to improve the patient's general weakness and fatigue. After three months of treatment, the patient's hair loss and general condition improved, and the color of the new hair was dark, despite the chemotherapy. The treatment did not improve other symptoms, such as bone marrow suppression and peripheral numbness. This case suggests that Bojungikki-tang could have a beneficial effect on chemotherapy-induced alopecia.
