Hair coloring before the 1980s was mostly to hide white hair by dying in black. With the introduction of color TV, however, the size of the coloring market has been expanding. Nowadays, artificial synthetic dyes are widely used, which, though advantageous in many points, have problems such as harmful effects on the human body, carcinogenesis, environmental contamination and damage on hair. On the contrary, natural vegetables obtained from Curcuma Longa L., A. catechu, polygonum indigo, henna, etc. are little harmful to hair or the skin of the head and cause few environmental problems. In addition, as they are natural materials collected from nature, they are considered positively by consumers. Thus the present study started from the necessity of research on the convenient use of environment?friendly and side-effect-free natural dyes, coloring technology for reproducing original color, the improvement of adhesion rate, etc. From the present research were obtained yellow color from Curcuma Longa L., brown from A. catechu, blue from polygonum indigo and orange from henna. It is expected that, based on materials from previous researches, there may be more researches on the use of natural dyes as hair colors.

NDM hair tonic is composed of several plant extracts which are known to be used in oriental medicine. This study was carried out to investigate the effect of NDM hair tonic on hair regrowth in an alopecia model of C57BL6 mice. Hair of six-weeks old mice were trimmed by electric clippers and electric shavers, so as not to damage the skin. The next day, mice without visible scraches were selected, randomized and separated in groups of 6 mice. There were four experimental groups including saline (negative control), 50% ethanol (vehicle control), 3% minoxidil (MXD), and NDM tonic. The test compounds were topically treated with 0.15 $m\ell$ per mouse per day for 2 weeks. The hair regrowth was determined photographically and histologically and the quantity of endocrine factors, IGF-1 and TGF-$\beta$, in the skin of mice was measured by PCR. No clinical signs were found in all animals. The topical treatment of NDM tonic for 2 weeks to dorsal skin accelerated hair regrowth faster than either the controls or MXD treatment. The NDM tonic treatment also promoted hair follicle development and elongation as compared with the controls or MXD treatment. Both NDM tonic and MXD treatment significantly increased the expression of IGF-1 and TGF-$\beta$ in the skin of C57BL6 mice as compared with the controls (p<0.05). These results suggest that NDM tonic has a hair growth activity and be useful for the treatment of baldness or alopecia.

This study examined the efficacy of restraining the increase of the bacteria colony of scalp according to the application of the Ayurvedic base oils and essential oils to scalp and hair. The result is as follows. The experiment illustrated that as the result of doing the paired sample t-test of a treated group and a control group according to constitutional oiling, the efficacy of the statistically significant decrease of the colony manifested in six tested groups except the group of Pitta constitution to which sesame and lavender were applied. Also, in a group that sesame was applied to Vata constitution and a group that coconut and lavender were applied to Pitta constitution, according to the passage of time, the result of being reduced the number of the colony was obtained and it showed that the oiling suitable for each constitution has the efficacy to decrease the colony of scalp. At the same time, regardless of the constitutions, the application of oils also showed the efficacy of restraining the increase of the bacteria colony of scalp. As the result of performing Paired Sample t-test for the subjective evaluation of the subjects in pre and post clinical testing, In the analysis of questionnaire that were obtained before and after the clinical testing, the results of all of the items except the item questioning a degree of inflammation appeared to be significant. That is to say, the subjects answered that a degree of keratin or a pain in scalp, an amount of sebum and a degree of hair damage were decreased after the application of oil more than before it. And in the question of a degree of hair damage, the application of oils were proved as having the efficacy to improve the hair damage.

Stress in skin plays a significant role in both the direct/indirect regulation of cellular processes occurring in hair, which in turn affect the hair cycle. However, experimental data regarding the effects of stress-related corticotropin releasing factor (CRF) released by stress on the apoptotic process involved in hair is limited. Therefore, we investigated the acceleration of early-stage apoptosis induced by atopy-related stress using a 2,4-dinitrochlorobenzene NC/Nga mice model. Expression of CRF, its related proteins, annexin V, and mitochondrial dysfunction were measured by immunohistochemical analyses. Atopic stress strongly stimulated stress hormones response, such as CRF and adrenocorticotropic hormone, in outer epithelial sheath of the hair. Moreover, its stress induced mitochondrial damage and early-stage apoptosis of cells in hair root. These findings suggest that hair damage due to apoptosis in atopy model is accelerated in a high CRF environment. Importantly, the effect of stress-related CRF on apoptosis processes involved in atopy dermatitis-related hair loss, suggests that the CRF-regulating development or maintenance materials may provide effective therapeutic strategies for hair health.

This study was aimed to investigate the improvement effects of kelp extract on the damaged hair by manufacturing hair quality improving formulation adding kelp extract and applying that in the damaged hair. With respect to the study materials, the formulation was manufactured with different strengths of kelp extract including 0, 2, 4, and 6 grams, adding perm base material. The manufactured formulation was applied to the decolored sample hair of Level 8 and its effects were measured and compared before and after its application. Tensile strength, absorbance using methylene blue, and gloss were measured as the tools to show the improvement effects of hair quality. To check the reliability of the results, statistical analysis was performed. Tensile strength showed to be increased in the Level 8 samples applied by the formulations containing 4- and 6-gram strength. Absorbance using methylene blue showed to be decreased in all the samples after the application, based on the absorbance results before and after the application. No difference was found in all the samples on the gloss. In conclusion, this study revealed that kelp extract could improve the damaged hair. Further studies are required to check the improvement effects on the damaged hair with multiple types of extracts and study methods.

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.

In this research, I chose and studied colorless hair manicure, which is well known for its useful point and supplement damaged hair glossy, luster, elastic and soft one. Also I studied and found hair protection effect by the management time of colorless hair manicure products, as below. Both level 3 and level 6 hairs, when they get damaged after dyeing, both hairs' strength and enlargement are affected. Manicuring two weeks after dyeing is more effective way than manicuring right after dyeing. So, in case of making good hair quality in manicuring dyed hair, it's more effective to manicure right after dyeing to both level 3 and level 6 hair. To complement hair's damage, however, manicuring two weeks after dyeing is the best effective way.

A frizz hair is referred to the fly-away hairs that have become bulky or deviated from the regular hair and the cause of that is not clear known. The internal lipids are related to the physical properties of hair such as elasticity and tensile strength and interracial studies have previously conducted to relate the lipid mass and Afrikaan hair, which has a lot of frizzy hair. Although washing hair is the only way to control the hair loss without damage of hair surface, the number of washing and lipid loss are not linearly correlated. In this study, the amount of lipid hair was analyzed by washing the hair with a few different types of shampoos containing various conditioning polymers and oils of different polarities. The results confirmed that the higher the polarity of the oil, the higher the lipid content. This method was applied to Indian frizzy hair to evaluate the degree of frizziness and found that the frizzy volume was more severe for a hair with less lipids. On the other hand, the frizzy hair volume of fly-away hairs was observed more broadly for the hairs with higher lipid contents. In addition, the friction on the surface of the hair did not differ due to the oil treatment. Taken together, it was concluded that hair frizzing was affected by the amount of lipids in the hair rather than by the adhesion between the oils. Thus, this study suggests that controlling the lipid contents in hair may be an important solution in the development of hair anti-frizzy technology.
