Hair is the part of body which expresses man into more manlike. When we create some artworks, we need the most suitable material for the artworks. Similarity, the healthy scalp hair condition and treatment are required to keep our hair clean and healthy. And the improper condition of scalp hair prohibits our hair from normal growing, proceeds the alopecia(loss of hair) and double our physical and mental stresses. The necessity of health treatment of scalp hair which was damaged by frequent permanent hair wave and hair coloring is on the rise. This study will present how to control and treat the scalp hair and will check how we feel about the necessity of scalp hair treatment. This study finally shows that people think their scalp hair conditions are not normal and chemically treated hair in spite of their natural hair. However, most people think that the scalp hair treatment is very useful to their hair and this result enables us to predict the future market of the scalp hair treatment business will be growing day by day. We need to study further not only scalp hair treatment but also prevention stage in order to keep the healthy hair and will check how we feel about the necessity of scalp hair treatment.

The purpose of these experiments is to improve the perm techniques which are fast growing and changing in our life style, for customer satisfaction and to use as basic data for academic purpose through comparing between two methods which are the new permanent wave treatment and the old one. I classified the hair samples to three kinds, which are healthy, normal, and damaged hair. This study is focused on the top part of hair sample which is damaged by strong and long-time sunshine. To get the best result, I use the scanning electron microscope (JSM-5200) as main device of these experiments. The followings are the results of these experiments. First, the new way of permanent wave technique has much more damage on hair than the old one. Second, There are big differences of damaging in this study. The harmed hair has worse result than the healthier hair.

Objective : This study was carried out to investigate effect of korean medicinal herbs-included hair tonic (MHT) and food (MF) on hair growth in an alopecia model of C57BL/6 mice. Methods : Six-weeks old mice were given laboratory rodent chow diet for 1 week. Then, we used a depilatory for hair removal on mice. The next day, mice were randomized and separated in 3 groups of 6 mice; normal group (N, vehicle epidermal application+normal diet-treated group), positive control group (C, 3% minoxidil sulfate epidermal application+normal diet-treated group), and the treatment group (T, HT epidermal application+ MF diet-treated group). The hair regrowth was determined by photograph, which was taken at 7, 14 and 21 days. And scoring indices, hair density and hair thickness, were evaluated by Folliscope at same day. In addition, the hair regrowth was analyzed insulin-like growth factor (IGF-1) in the dorsal skin of mice. Results : As a result, not only external appearance but also hair density and hair thickness on dorsal skin were increased more in C, T groups than in N group at 21 days with mixed treatment. Therefore, distinct regrowth pattern is appeared by treatment of herbal tonic and natural food for 21 days. Also, the expressions of IGF-1 on dorsal skin were higher in C, T groups than in N group. Conclusion : These results suggested that this herbal hair tonic and natural food has hair growth promoting activities and may be useful for treatment of bald or alopecia.

This experiment was investigated the effects of fresh and ginger processed Pinelliae Rhizoma extracts on hair growth activity, and its fractions(chloroform, ethyl acetate and water fractions) obtained from fresh Pinelliae Rhizoma on hair growth activity of the normal and spontaneous alopecia areata model of C57BL/6N mice for 16 days. The results were as follows: In fresh Pinelliae Rhizoma extracts treated group, hair growth effect was observed in whole skin area(100%) all the normal mice in whose hair had been clipped on 16th days. In ginger processed Pinelliae Rhizoma extracts treated group, hair growth effect was observed in whole skin area in 25% of normal mice in whose hair had been clipped on 16th days. But in control group, hair growth effect was observed in a part of whole skin area in 25% of normal mice. In fresh Pinelliae Rhizoma extracts treated group, hair follicles of middle stage of anagen phase was observed and it were grown down to subcutaneous tissue of skin in all the mice on 10th day. But in ginger processed Pinelliae Rhizoma extracts treated group and control group, Most of hair follicles of telogen phase was observed in skin. The treatment of extracts of fresh Pinelliae Rhizoma increased the expression of TGF-$\beta$(146%), IGF(107%), and prolactin(115%) in the skin of normal C57BL/6N mice compared to control group(100%). But expression of placenta lactogen(93%) was decreased in the skin of normal C57BL/6N mice compared to control group(100%). In spontaneous alopecia model, The hair growth activity of fresh Pinelliae Rhizoma extracts treated group(100%) was observed to be strong compared with the control group(20%) on 15th day. Hair growth activity on chloroform fractions of fresh Pinelliae Rhizoma extracts was observed in whole skin area in 75% of normal mice on the 9th day. In water and ethyl acetate fractions, hair growth activity was observed in a part of whole skin in 75% and 25% of normal mice, respectively. but hair growth activity of control group was not observed. After application of fractions of fresh Pinelliae Rhizoma extracts for 10 days, hair follicles of chloroform fraction treated group was observed middle stage of anagen phase and hair follicle were grown down to subcutaneous tissue of skin in all the mice. But hair follicles of initial stage of anagen phase were observed in water and ethyl acetate fractions. Most of hair follicles of telogen phase was observed in skin of control group. These experiments suggest that extracts of fresh Pinelliae Rhizoma may stimulate the topical hair growth activity and its chloroform fractions can be useful for treatment of alopecia areata.

To investigate the hair growth activity of fractions and extract of Arisaematis Rhizoma in the hair removed skin of normal and spontaneous alopecia areata model in C57B/6N mice. These experiments were performed with the macroscopic, microscopic, immunohistochemical(VEGF, c-kit, PKC-${\alpha}$, TGF and FGF) and RT-PCR(TGF-${\beta}$, IGF, prolactin and placenta lactogen) methods. The results were as follows: Macroscopic observation after topical application of vehicle, 50% EtOH as control and extract of Arisaematis Rhizoma to the hair removed skin of C57BL/6N mice on the 9th, 11th and 15th day. Extensive hair growth activity was observed in treated group with extract of Arisaematis Rhizoma on the 9th, 11th and 15th day. In Arisaematis Rhizoma extracts treated group, hair follicles of middle stage of anagen was observed and it were grown down to subcutaneous tissue of skin in all the normal mice on 15th day. But in control group, most of hair follicles of telogen phase was observed in skin. The treatment of extract of Arisaematis Rhizoma increased expression of IGF(145%) and placenta lactogen(108%) in the skin of normal C57BL/6N mice on the 11th day compared to control group(100%). But expression of TGF-${\beta}$(90%) and prolactin(91%) decreased in the skin of normal C57B/6N mice on the 11th day compared to control group(100%). After application of fractions(chloroform, ethyl acetate and water fractions) of Arisaematis Rhizoma extract for 9th day, hair growth effect was observed in whole skin area in 50% of normal mice. But in control group, hair growth effect was not observed in whole skin area of normal mice. Immunoreactive density of VEGF, c-kit, PKC-${\alpha$ and FGF in skin of fractions of Arisaematis Rhizoma extracts was strongly stained in epidermis, bulge, secondary hair germ cells, cutaneous trunci m., subcutaneous tissue, root sheath compare to control group on the 9th day. In spontaneous alopecia areata model, The hair growth activity of Arisaematis Rhizoma extrat treated group(75%) was observed to be strong compared to control group(O%) on 7th day. These experiments suggest that fractions and extracts of Arisaematis Rhizoma may stimulate the topical hair growth activity. Thus it can be useful for treatment of alopecia areata.

Hair is made of proteins containing various amino acids. Ultraviolet (UV) radiation is believed to be responsible for the most damaging effects of sunlight, and also plays an important role in hair aging. The purpose of this study was to investigate the changes in morphological and chemical structures after ultraviolet B (UVB) irradiation of human hair. The UVB-irradiated hair showed characteristic morphological and structural changes, compared to those of the normal hair. The result from a scanning electron microscope (SEM) equipped with an energy dispersive X-ray diffractometer (EDX) showed that the scale of UV-irradiated hair appeared to be rough and the amount of oxygen element was higher than that of the normal hair. Fluorescence and three dimensional (3D) topographical images were obtained by a confocal laser scanning microscope (CLSM). In 3D images, the green emission intensity of normal hair was much higher than that of fluorescing UVB-irradiated hair. The intensity of green emission reflects the intrinsic fluorescence of hair protein. Also, a fluorescent imaging method using fluorescamine reagent was used to identify the free amino groups resulting from a peptide bond breakage in UVB-irradiated hair. Strong blue fluorescence of UVB-irradiated hair, which indicates a very high level of amino groups, was observed by CLSM. Therefore, the fluorescamine as an extrinsic fluorescence could provide a useful tool to identify the peptide bond breakage in UVB-irradiated hair. Infrared image mapping was also employed to assess the cross-sections of normal and UVB-irradiated specimens to examine the oxidation of disulfide bonds. The degree of peak areas with strong absorbance for the disulfide mono-oxide was spread from the outside to the inside of hair. The spectroscopic techniques used alone, or in combination, launch new possibilities in the field of hair cosmetics.

This Study was conducted in order to provide a satisfying beauty service to customers by investigating the effect of hair thickness on personality and attitude of hair style. It executed a survey of customers within the age of $20{\sim}}40$ who come and go to beauty salons, dwell in Kyeong-gi and Seoul. First, it investigated the difference of blood types depending on hair thickness. Second, it investigated how hair thickness affects on types of personality. Third, it investigated the difference of hair style attitude depending on hair thickness. We picked normal hairs for mineral test from our salon customers of the occipital region, except coloring hairs, white hairs. The hairs were picked 2 cm off from the scalp. In the result, many people with thick hair were found to have the blood type O, and many people with thin hair were found to have the blood type A. Also, in the types of personality the owners of thick hair and thin hair were highly found to have characters of both sexes, the owners of normal hair were highly found to have feminine characters. Many of the owners of thick hair appeared to prefer short hair styles, a high percentage of the owners with thin hair appeared to have long hair styles, A type people who are introspective prefer soft and long hair styles which have less movement.

This thesis aimed to reduce the differences of hair color when hair coloring, so it researched the differences & changes in hair color before shampoo v.s. after shampoo and dry on different heat processes when acid hair color dyeing. Five hair color dyes (Y, R, B, G, Br) manufactured by two different corporations were used. The acid hair color dyes were tinted on black and bleached hair pieces subjected to 3 different heat process; 1. Normal Temperature($25^{\circ}C$, 30min.) / 2. Heating($40^{\circ}C$, 15min.)+Normal Temperature($25^{\circ}C$, 15min.) / 3. Heating($40^{\circ}C$, 30min.). Color numbers were divided by NCS value, chroma, and hue. Statistical averages were derived and t-test was conducted using SPSS V12. Hair color differences and changes were drawn on an NCS chart using Photo Shop PS. The conclu is; If acid hair colorings are separated by a heating process, hair value & chroma change before shampoo vs. after shampoo & dry regardless of the color of hair and the heat process. Hue is not changed or shifted counter clockwise NCS color circle, but some exceptions, and it's the same when the total heat process results are combined. Black hair's value shifted downward and chroma left, and hue stayed either neutral or one color or it shifted counter clockwise on NCS color circle. Bleached hair's value shifted upward and chroma right, and hue stayed one color or shifted counter clockwise, but some exceptions. And it can be shown on NCS chart.

Hair is a dermal adjunctive organ that protects the body from external physical and chemical stimuli; hair undergoes anagen, catagen, and telogen phases, with hair-loss occurring during the telogen phase. Alopecia is a condition wherein a person undergoes hair-loss far exceeding the normal amount, owing to diverse external factors. Wild beans are rich in isoflavone and amino acids known to prevent hair-loss; compared to cultivated beans, many wild bean species have higher protein content. This study aimed to develop a hair growth promoting solution, with superior hair growth promoting effects and fewer side effects, using naturally obtained Glycine soja Siebold et Zucc (GSSZ) extracts. Seven-week-old C57BL/6N male mice were classified into different experimental groups. Hair growth was observed in GSSZ-treated mice, and compared against that seen in 3 % minoxidil (MXD, positive control)-treated mice. Visual observations revealed a greater reduction in hair-loss in MXD and GSSZ application groups, compared to that in TXN group (hair loss induction using 1 % testosterone). Evaluation using an image analysis software revealed that compared to the positive control, TXN + GSSZ group showed the highest hair growth. TXN + MXD and control groups exhibited similar follicular cell growth, while the hair growth promotion patterns were similar in the negative control (normal), TXN + GSSZ, and TXN groups, as observed via histological analysis. GSSZ did not induce cytotoxicity (even at 2 mg/mL) in keratinocytes and dermal papilla cells; alternately, dermal papilla cell proliferation was activated in a (GSSZ) concentration-dependent manner. Therefore, the GSSZ extract promoted hair growth and increased hair growth-related cell activity, and could therefore be utilized in alopecia treatment.

This experiment investigated the effect of mixed extracts obtained from Mylabris phalerata Pall. and Drynariae Rhizoma on hair growth activity of the normal and spontaneous alopecia areata model of C57BL/6N mice for 16 days. First, we examined morphological regrowth of hair in normal and spontaneous alopecia model of C57BL/6N mice. Second, we examined immunoreactive density of vascular endothelial growth factor(VEGF), c-kit and protein kinase $C-{\alpha}(PKC-{\alpha})$ in skin of normal C57BL/6N mice by immunohistochemical methods. Third, we investigated expression of $TGF-{\beta}$, prolactin and placenta lactogen after topical application of mixed extracts of Mylabris phalerata Pall. and Drynariae Rhizoma to skin by RT-PCR. The results were as follows: Hair growth effect from middle and high concentration of mixed extracts of Mylabris phalerata Pall. and Drynariae Rhizoma was observed in 80% of normal mice in whose hair had been clipped in 15th days. Hair growth effect of all concentrations of mixed extracts of Mylabris phalerata Pall. and Drynariae Rhizoma was observed in 100% of spontaneous alopecia model of C57BL/6N mice in 15th days. Immunoreactive density of VEGF, c-kit and $PKC-{\alpha}$ in skin of all concentrations of mixed extracts of Mylabris phalerata Pall. and Drynariae Rhizoma were strongly stained in epidermis, bulge, secondary hair germ cells and cutaneous trunci m. compare to control group in 10th day. In experimental III group, Immunoreactive density of VEGF, c-kit and $PKC-{\alpha}$ in skin were strongly stained in inner and outer root sheath of skin. The treatment of mixed extracts of Mylabris phalerata Pall. and Drynariae Rhizoma increased the expression of $TGF-{\beta}$, placenta lactogen and prolactin in the skin of normal C57BL/6N mice compared to control group. These experiments suggest that mixed extracts of Mylabris phalerata Pall. and Drynariae Rhizoma may stimulate the topical hair growth activity and it can be useful for treatment of alopecia areata.
