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.

In this study, the survey targeting 180 in-service hair dressers from beauty salons located in Seoul was carried out in order to determine the connection between the practical tasks(scalp, shampoo, cut, blow dry, roll setting, blow dry, coloring) of national hairdresser licensing examination and the practical field. The utilization level of 7 practical subjects tasks was average except for hair coloring which showed a high support of spread and spread-skill tasks. Also, the utilization level of two subjects including haircut and coloring gave a positive influence on the practical skill (p<0.05). Therefore, practical application of haircut which is one of the most important subjects for in-service hair dressers and high quality education for customer satisfaction are necessary and it is necessary to check other subjects which have no influence on the practical field again.

Modern people express their beauty through hair coloring, but hair can be damaged by repeated chemical treatments. In order to increase the durability of dyeing and minimize the hair damage, in this study, the acidic amino acids including aspartic acid (Asp) and glutamic acid (Glu) were used to post-treat hair during hair coloring. The post-treatment with 0.75% Asp and Glu solution was carried out at room temperature for 20 minutes after dyeing bleached hair with cherry red and blue silver colors. After repeated shampooing of 1, 5, 10, 15, 20, and 25 times, L^*a^*b^* value of dyed hair was measured to confirm the dyeing durability, and the changes in tensile strength, porosity, and surface properties of the hair were also analyzed to determine the condition of the hair. In the case of cherry red and blue silver staining, the Asp and Glu experimental group showed higher color persistence than the control group, and the Asp and Glu experimental group showed higher tensile strength, lower porosity and smooth surface properties than the control group. In particular, the Asp test group showed superior color persistence and lower hair damage than the Glu test group. This study, therefore, if damaged in dyeing and bleaching in the field of hair after treatment with asp glu a combination of hair cosmetics in the development of basic data look forward to be.

In order to express the ideal appearance, everyone, regardless of age or gender, invests boldly in appearance management. In particular, hair coloring and hair styling using irons are widely used and used. have. Therefore, for the purpose of presenting the efficient use of flat irons, the study of thermal analysis of virgin hair and bleach hair in 120℃ heat treatment is conducted. As a result of the study, it was found that the overall weight of bleached hair decreased more than that of virgin hair at all treatment temperatures of flat irons. Through this thermal analysis study that measures the weight change according to the temperature rise of virgin and bleached hair, beauty consumers provide information on the optimal temperature flat ironing procedure that can minimize hair damage and discoloration while maintaining color in hair subjected to physical friction. It is believed that it will provide them efficiently.

As the importance of the beauty to pursue beauty comes to the fore, the market size of hairdressing industry including hair dyeing is getting bigger. In case of continuously applying an oxidative dyeing agent commonly used in hair salons, as hair damage is inevitable, we investigated morphological changes of hair treated with a neutral oxidative dyeing agent. In the experiment results, Between the control and the 6N-7N experimental groups, there was a significant difference in Max. modulus and Tangential modulus according to Max. load, Max. stress, Max. elongation, Break load, Break stress, Break elongation, and strain section. There were the highest values in Max. load, Max. stress, Max. elongation, Break load, Break stress and Break elongation in the control group, and there was no tendency to decrease significantly according to the treatment of the experimental group. Max. modulus and Tangential modulus according to the strain evaluation section did not show a tendency to increase or decrease constantly, although there was a difference between the control and experimental groups. This study attempts to provide basic data for the development of oxidative dyeing agent that minimizes hair damage and to establish the foundation for understanding the correlation between hair designers' oxidative dyeing agent and hair health.
