It is considered to be important to create aesthetically beautiful style through the change of external shape, however for the hair stylists, whose beauty expression is through hair, the role of hair doctor is becoming even more important with focus to improve the hair healthiness. Hair clinic is management of hair and scalp. It is the management process of preventing damages, while improving and cultivating healthy and shiny hair. The current concept in hair management is moving from simple hair styling to emphasis at hair management. As far as hair management is concerned, it usually includes treatment tools such as shampoo, conditioner, hair treatment and scalp scaling system, which is used for diagnosis of hair condition in order to treat the scalp. As the interest of hair healthiness becoming more wide spread, so does the breadth of clinic menu. The wide choice is to fulfill the profound desire of people, whose demands are simply to have variety in their choice. This is resulting in faucets of new value-added and differentiated products. The values that make-up the hair styles consist of mainly design (trend, preference), function(styling, management convenience) and clinic(hair quality improvement, damage repair). Shampoo and conditioner have gone beyond their original function of cleansing to providing combinational functions of treatment, to care and remedy, and advanced massage effectiveness. These are, to name a few that seem to go beyond their original function to satisfy the mental healthiness in people, the King Kong shampoo of shampooings in forward-backward manner, 5-minute shampoo massage that applies sports and relaxation massage, scalp acupunctural message and aural(ear) massage. More and more people are complaining about the damaged hair and hair loss problems due to perms, dyeing and bleaching of hair, in addition to natural scalp and hair damaging factors. Such complaints have stimulated many beauty products and various hair treatment systems being introduced with focus to provide nutrition and prevent damages to scalp and hair. As the living standards improve and the desire of people is to pursue differentiated lives, their demand also increases in hair styling products to fulfill the needs of healthy and aesthetical aspects of their lives.

Hair dyeing, hair perming, and daily hair dryer use can substantially damage hair. Consequently, the demand for products containing natural ingredients for the care of damaged hair is growing. Although polyphenols with antioxidant effects are often used for hair conditioning, few studies have focused on hair conditioning, and the potential of Sparassis latifolia mushroom extract for hair improvement has not been evaluated to date. In this study, the antioxidant activity of and polyphenol content in hot water, 70% and 100% ethanol (EtOH), n-hexane, ethyl acetate (EtOAc), and water extracts of S. latifolia were analyzed. A hair treatment containing S. latifolia extract was prepared, and its effect on damaged hair was evaluated. The highest antioxidant activity was observed in the hot water and EtOAc extracts. Moreover, polyphenol analysis using high-performance liquid chromatography and liquid chromatography-mass spectroscopy confirmed that the EtOAc fraction has relatively high contents of specific polyphenols beneficial for hair. Based on these results, a hair treatment containing S. latifolia extract was applied to damaged hair, and hair improvement was evaluated using hair thickness, tensile strength, and scanning electron microscopy. The hair treatment containing 70% EtOH extract effectively improved hair condition. We postulate that this improvement was caused by the high hydrophobic polyphenol content in the 70% EtOH extract.

This study classified the hairstyle types of flight attendants in flight on A airline, the largest low-cost carrier in Asia. The cabin crew does not maintain a constant commute time, but the hairstyle will change with the diversification of commute time according to flight schedules. Therefore, in the case of a female cabin attendant, if there is a lot of time before going to work, a hairstyle such as a up hair style may be maintained. However, when you have less time to trim your hair, keep your daily hairstyle, such as one-length cuts and gradation cut, or keep your hair ponytail-like. The cabin crew maintains a variety of hairstyles, but the color of the hair prefers natural brown or slightly lighter dyeing, and the lighter hair due to excessive bleach is not preferred.

Modern people are investing a lot of time and economically in their appearance as a means of expressing their aesthetic desires. They have a lot of hair dyes that make up most of their appearance, but their hair damage is serious. Especially, they use hair dyes which are very popular among the hair cosmetics that make up most of their appearance, but their hair damage is serious. The purpose of this study is to investigate the hair tensile strength of hair with oxidative hair dye to induce styling while minimizing hair damage. The results showed that the Max. load, Max. stress, Max. elongation, break load, break stress, break elongation, maximum modulus and tangential modulus according to evaluation interval were significantly different between control and 8N-10N experimental groups. The maximum modulus and tangential modulus for the strain interval did not show tendency to increase or decrease constantly, although there was a difference between the control and experimental group. Therefore this study was conducted to investigate the correlation between hair loss and hair damage through the treatment of high grade oxidative hair dye, which is widely used in ield of industry. We want to provide application data.

Objectives: This study evaluated the skin permeability of lawsone in henna hair dyes to understand the exposure characteristics of henna hair dyes in the human body. It examined the protective effects of protectants by applying protectants A, B, and C to test skin. Methods: Skin absorption tests were conducted using Franz diffusion cells according to OECD test guideline 428. After applying one kind of natural henna hair dye and chemical henna hair dye, respectively, to a standardized pig skin model, samples of receptor fluid were collected at 1h, 3h, 6h, and 24h. The skin permeation of lawsone was determined using HPLC. After the skin absorption experiment, the skin to which hair dye was applied was analyzed to determine the residual amount of lawsone in the skin. Results: The cumulative permeation of both natural and chemical henna hair dyes increased over time, and the natural henna hair dye had a flux value (t=3.194, p<.05) high both in the K_p value (t=3.207, p<.05) and the residual amount (t=22.701, p<.001). For skin treated with a protectant, the cumulative permeation of natural henna hair dye 24h control and the cumulative permeation of protectant A, B, and C increased over time. Flux and K_p values were in the order control > protectant A > protectant C > protectant B. The residual amount (F=4.469, p<.05) was in the order of protectant C > protectant A > protectant B > control. At 3h, the dye application time of natural henna hair dye, the lawsone flux value (F=4.454, p<.05) and K_p value (F=4.455, p<.05) were higher in the control group than in the protectant groups. The 24h cumulative permeation of the chemical henna hair dye increased with time in both the control and the protectant groups, and the flux and K_p values were in the order of protectant A > protectant C > protectant B > control. The residual amount (F=7.901, p<.01) was in the order of protectant B > protectant A> protectant C > control. Conclusions: Within the normal dyeing time for henna hair dye (three hours for natural henna hair dyes and 30 minutes for chemical henna hair dyes) lawsone skin penetration was not observed even when no protective agent was applied. After that time, however, evidence of skin penetration and retention of lawsone and the protective effect of protective agents were observed.

The goal of this study was to get the basic data for the domestic cosmetic industry, through analyzing female college ,students’ responses to cosmetic care of hair and their behavior, and their preference for hair cosmetics and brands. In their level of understanding and concern of hair cosmetic care, as well as their general knowledge, ‘dyed or decolorized hair’ types had the highest response rate at 49％, followed by ‘permanent wave’ type at 39％. Thus they were very interested in hairdressing-related operations, and even they made an attempt to do it directly. In the ways and management for dealing with harmful side effects caused by dyeing, decolorizing, or permanent, 74.7％ of the respondents experienced adverse effects, as well as having complaints, after permanent wave. Of the complaints 245 students experienced, ‘hair damage’ was the highest rate of 42.4％, followed by ‘unsatisfied with hair style’ at 19.8％. From the above results, female college students showed a various interest in hair cosmetic care; however, they had little knowledge in this regard. Accordingly, it is necessary to educate them for the segmentation of hair cosmetics and the appropriate hair care, to meet their diversified cosmetic needs which becomes diversified, and to offer them the correct information of hair beauty.

Henna is a natural colorant and has been used to dye hair, skin and leather since civilization began. It has reddish brown to orange shade. The major color components of Henna are Lawsone(2-hydroxy-1,4-naphthaquinone) and Luteolin (3',4',5,7-tetrahydroxy-flavone). In this study, various fibers containing the nitrogen component, especially used fur underwear, were dyed with Henna under various dyeing conditions, then dyeing characteristics, color fastness, and anti-bacterial properties were evaluated. from the results, Henna has good affinity to the chlorinated wool>wool>Pu/nylon>nylon>soybean>silk in decreasing order. The color fastness of the wool fabric dyed with Henna to washing, dry-cleaning, and perspiration showed 4-5 grade. The color fastness to light was 3rd grade. These results are relatively good comparing with other natural dyes. Moreover dyed fabric with Henna showed excellent antibacterial activity.

In this study, the emulsion stability of henna, a natural hair dye, according to the content of cetyl alcohol, one of the emulsification stabilizers, was analyzed, and the content of cetyl alcohol showing the most stable emulsification was confirmed. To analyze the emulsion stability, differences in particle size, particle shape, viscosity, and color after dyeing were compared according to the content of cetyl alcohol. As a result of dynamic light scattering (DLS) zeta analysis, cetyl alcohol 3% showed the highest zeta potential value of 115.9 mV, and the particle size distribution was henna in which a cream-type hair dye containing 3% cetyl alcohol was dispersed in distilled water. The width of the particle size distribution was narrow compared to. As a result of viscometer analysis, the viscosity increased as the content of cetyl alcohol increased. As a result of measuring the henna pH of the cream formulation, it was measured in a pH range suitable for the scalp. As a result, emulsion stability increases as the content of cetyl alcohol increases in henna cream formulations for hair dye.

This study investigates the relationship between the purchasing behavior for hair-care products and the attitude toward hair-care products by adolescents. A total of 412 middle and high school students located in Seoul and Gyunggi-do province participated in this research. SPSS 12.0 for Windows Program was utilized for statistical analysis. As a result, the hair concerns and the satisfaction of adolescents as well as their attitudes towards hair-care products were significantly affected by gender, school level, and educational experiences. Female high school students with some degree of educational experiences had a more rational and brand-oriented attitude. Students having a higher rational and brand-oriented attitude bought hair-care products in regards to the quality of the product and environmental impact. On the other hand, those having a conspicuous and fashion pursuit attitude showed an image and fashion concern purchasing behavior. Adolescents usually purchased styling and dyeing products at a cosmetic specialty store and hair-care cleaning products from a discount store. They obtained the information about hair-care products from relatives, personal experiences, and TV advertisements.
