외모의 중요성이 날로 증가하는 사회적 분위기 속에서 현대인의 아름다움에 대한 노력과 욕구는 더욱 활성화하고 다양해지고 있으며 이러한 영향으로 인해 뷰티미용 산업은 점점 세분화, 전문화되는 추세이다. 현대인의 과도한 퍼머넌트 웨이브나 헤어 컬러링으로 말미암아 모발 손상은 불가피한 현실인데 모발이 손상될수록 모표피가 벗겨져서 탈락하면서 인장력도 감소하여 헤어스타일링이나 펌 이후 만족도도 상대적으로 감소한다. 따라서 손상 모발에 대한 관리는 필요하지만 시중에 유통 중인 헤어 트리트먼트제는 인공합성 제품이 대부분을 차지하고 있어 인체에 유용한 항산화 물질을 함유한 헤어 트리트먼트 제품 개발이 필요하다. 본 연구에서는 단풍잎 추출물을 컬러링 한 모발의 역학적 변화에 미치는 영향을 분석하여 단풍잎의 손상 모발 회복과 모발 건강 개선을 위한 헤어 트리트먼트제 원료로서의 가능성을 연구하였다. 본 연구는 향후 천연물을 활용한 모발 미용제품 개발을 위한 기초 자료로 활용되리라 사료한다.

This study attempted to investigate what color would fade more during hair bleaching and examine what should be done to make hair color last longer. For this, hair was colored differently in ash gray with permanent hair dyes and semi-permanent hair dyes each. Hair in multiple levels was created through such bleaching. Color retention was improved in consideration of the degree of color fading in sample hair. In terms of post-bleaching hair coloring, it was more efficient to color hair by eliminating redness without hair damage after shampooing with a permanent hair dye. Therefore, it is anticipated that the study results would be highly useful for beauty salons to find a base level in consideration of bleaching effects and make improve- ments according to hair retention and moisturizing effects.

This study comparatively analyzed hair bleaching and degree of damage by the temperature of a heating tool after coloring hair with a permanent, semi-permanent or plant hair dye. According to analysis by spectrophotometer, 'semi-permanent hair dye' was the highest, followed by 'permanent hair dye' and 'plant hair dye' in terms of changes in $L^*$ values. In terms of changes in hair shape when analyzed using FE-SEM, 'semi-permanent hair dye($150^{\circ}C$ or lower)' was the greatest, followed by 'plant hair dye($180^{\circ}C$ or lower)' and 'permanent hair dye($200^{\circ}C$ or lower)'. Therefore, it is reasonable to flat iron hair at low temperature. According to the test, amino acid values gradually decreased in both bleached and colored hair. The results obtained through TGA-based thermal analysis confirmed that as brightness increases, hair moisture contents decrease. This study aimed to protect hair by suggesting a correct use of a flat iron by the hair dye type during hair coloring. It appears that the study results would help hairdressers minimize hair damage by using a hair dye at proper temperature.

These days hair perm and dye is a modern trend that women prefer to create their own image and personality. However, chemicals for hair perm and dye are easy to damage hair. This study, then, is to find out some effective skills to minimize hair damage when hair perm and dye is done in a same time. The subjects were 200 hairs picked from five healthy women in their twenties which have not been permed and dyed since one year and more ago. The experimental group was divided into two groups: 1)the perm- nutritional treatment- dye (PNT) group 2)the dye- perm- nutritional treatment(DPN) group. After experiments, the states of "hair scale", "hair damage", and "color tone in dyed hair" were compared between two groups. The results are as follows: to lessen hair damage when hair perm and dye is done in a same time, nutritional treatments must be necessarily used on hair. To make hair colored more clearly when hair dye is done, it is more desirable to use nutritional treatments on hair.

The present study was to investigate the effects of different types of conditioner on the morphological changes of hair cuticles after coloring treatment. The virgin hair, aged 22 years served as a subject. Coloring treatment was done with a commercial hair dye agent for 35 minutes as routine procedures at $25^{\circ}C$, 50% R.H. environmental condition. The two different types of conditioner, Essence and LPP were applied to the colored hair 10 times with 2 days interval for 20 days. The hair cuticles were observed by a scanning electron micro scopy before and after coloring and conditioner treatment. The main results were as follows. Coloring treatment damaged the hair cuticles, and both of Essence and LPP had a direct conditioning effect. Also, the damaged hair cuticles were recovered by the repeated application of hair conditioner. Moreover, LPP was more effective in hair curing compared to Essence. These results show that a hair conditioner can be helpful to keep healthy hair and to shorten an interval of coloring.

This study is to make pH 9 reduction by adding NaOH to 1, 3, 5, 7, 9, 11% solution of thioglycollic acid, cysteine, cysteamin, to add it on helically winded natural hair and colored hair and leave them for 20, 40, 60 minutes, to add $NaBrO_3$ oxidant for 15 minutes and to compare and analyze the wave form. This study showed the results of permanent using thioglycollic acid, cysteine, cysteamin. In the permanent wave form according to the kind of reductant, concentration, and processing time, there were a little difference between thioglycollic acid and cysteine. But cysteamine not only showed apparent difference but also formed strong and elastic wave. The permanent wave is affected by the diagonosis of hair, the choice of permanent solution and the processing time. Therefore the scientific diagonosis of hair is to be considered first of all. By choosing the kind of solution, the concentration and the processing time according to the results of hair diagonosis and wave form, we can prevent the lengthening and damage of hair.

Improving work efficiency and satisfying customers through personalized services is becoming more important in an increasingly competitive hair industry. Wearables may help to improve hair designers' work efficiency and customer satisfaction by analyzing customer and hair designers' conditions and provide hair stylingrelated data. However, there is limited research on developing wearables for hair designers (WHDs), and many existing wearables were developed without understanding user needs and perceptions. This research investigated preferences, perceptions, and intentions on WHDs based on hair designers in the U.S., which is the largest hair market. Specific design options that hair designers preferred and possible options to meet requirements that hair designers expect for wearables were identified and suggested in WHD design guidelines. Second, most people preferred a WHD design of a black-colored bracelet/watch that can be a necklace designed with preferred functions; in addition, 3D virtual images and 3D printed models were prototyped. Third, developed designs were evaluated. More than 70% of users were satisfied and considered it as useful and easy to use, with an intention to purchase. The results are expected to provide insights to designers when developing WHDs.

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.
