Generally, hair treatments by complementary actions to give a sense of activity are permanent setting, dyeing, and bleaching, etc. In this study, we investigated the wave formation ability and hair damage occuring in permanent setting and bleaching process. The wave formation ability was evaluated by the differences of length and curl diameter after permanent setting. And the hair damage was also evaluated by the protein release ability and SEM of hair. The bleached hair immediately after permanent setting treatment has better wave formation ability, but much more damaged than the bleached hair after rinsing thoroughly with warm water. It was considered that the chain of hair keratin broke down easily by the bleaching action in the existence of permanent setting agents.

As you see, there's no difference of the hair's before and after Magic straight permanent on the example A's hair's thickness, the rate of the tense and the C's rate of the tense, but we can find that there are a lot of difference of the A's strength of the hair, the B's hair's thickness, the strength of the hair, the rate of the tense, the C's hair's thickness, and the strength of the hair on the before and after the Magic straight permanent. That is to say, there are more damage on the condition of normal hair than the one after the Magic straight permanent. On the change of the hair's physical character, before the permanent, the hair's schedule was regular and had the healthy head skin of clear mutual boundary But after the Magic straight permanent wave, the hair's schedule changed to unregural, had unclear mutual boundary of the head skin and the schedule was taken off so the cortex showed up and so on, every condition of the damage was very heavy. On the effect of the treatment, even though it gaves the worth condition of the hair, after the Magic straight permanent formally the change of the hair gives the beautiful straight.

In this paper, the damage of hair and wave shape in process of the dyeing, bleaching, and permanent hair wave are simulated. The virgin hair that do not process the dyeing, bleaching, and permanent hair wave becomes stable in the scale type. On the other hand, the hair that deals with the dyeing, bleaching, and permanent hair wave is heavily damaged in the scale type. It is observed that the higher pH is decided, the higher the hair is damaged because the scale damage in the bleaching hair is more heavily damaged than the dyeing hair. In case of executing the permanent hair wave, the processing of the plaine rinsing becomes less in the scale damage of the hair and better in the wave form. Therefore, it is found that the processing of the plaine rinsing to improve the wave form and to prevent the hair damage is needed.

This study attempted to determine the effects of fermented green tea extracts on hair by using them in a perm. For this, hair is bleached, and then the fermented green tea extracts and water were supplied to the hair using a mist sprayer. Then the hair was permed, and hair damage was tested. Regarding hair moisture levels and wave formation, specifically, the morphological changes of hair were investigated with the Scanning Electron Microscope(SEM). The study results found the following. In terms of wave formation, the fermented green tea extract-based perm was much better than the general perm. In addition, hair bleaching was more serious in the latter. According to analysis on hair moisture using SEM, hair damage was more prevalent in the general perm as well. Therefore, it was confirmed that green tea extract-based perms cause less damage to the cuticle. In other words, the potential of fermented green tea extracts as a hair cosmetics material was discovered. Furthermore, it appears that the study results contribute to the development of low-irritating scalp and hair care products using the anti-inflammatory and antimicrobial properties of the fermented green tea extracts.

To screen the effective materials for hair loss treatment, the Gamissanghwa-tang extracts were tested. As a result we found that the Gamissanghwa-tang extracts have the hair growth promoting effect. After topical application of each test materials to the back of CS7BL/6 mice, the earlier conversion of telogen-to-anagen phase was induced. In the experiments of 5α-reductase type II inhibition assay, Radix Paeoniae Alba, Semen Cuscutae showed effective potential to inhibit the activity of 5α-reductase type II. And hair growth index of the Gamissanghwa-tang extracts ranked as 1.2, especially the hair growth index of Fructus Rubi is highest as 1.8. But there were no plant extracts which have effect on the DNA proliferation of hair dermal papilla cell measured by [³H]thymidine incorporation, the expression of growth factors such as IGF-I, KGF, HGF estimated by RT-PCR and protein synthesis of vibrissae hair follicle measured by [/sup 35/S] cysteine incorporation. Cortex Cinnamomi showed anti-bacterial effect on P. ovale, Radix Paeoniae Alba has the highest radical scavening activity and Radix Glycyrrhizae has the highest effects of NO synthesis. These results suggest that Gamissanghwa-tang can be used as a potent treatment agent for helping hair growth stimulation.

This study was used a thermogravimetric analyzer to determine thermal characteristics, a hair analysis system to examine morphological changes of wefts-human hair, poly vinyl chloride(PVC) and polyethylene terephthalate (PET)-used in manufacturing wigs. According to a flammability test on human hair and synthetic wefts for wigs, the best results were observed in human hair. According to a thermal test, PET was the best in terms of thermal stability. Also good tensile strength was observed as well. In a scanning electron microscope observation, no human hair scale layer was found because of chemical treatment. In the PVC sample, homogeneous unevenness was observed. Due to a lack of human hair supply and increase in its price, recently, PET weft has emerged as a great substitution for human hair. Because it can be curled using an electric curling device and is more efficient than the conventional non-flammable material PVC in terms of thermal resistance, it will become the next-generation weft for wigs.

Bonogen shampoo is composed of several plant extracts which are known to be used in oriental medicine. This study was carried out to investigate the effects of Bonogen shampoo on hair growth in an alopecia model of C57BL/6 mice. There were eight male and female experimental groups including distilled water(DW: negative control), a commercial shampoo[M], 3% minoxidil (MXD) and Bonogen shampoo(BNG). Dorsal skin hair of six-week-old mice was trimmed with an electric clipper carefully not to damage the skin. The next day, mice without skin scratch were selected, randomized and separated in 10 mice per group. The test compounds were topically treated with 0.15 ml per mouse or dorsal skin for 21 days daily and then washed thoroughly with DW. The hair regrowth was determined photographically at 0, 4, 7, 10, 15, 18, and 21 days and histologically at day 21. No clinical signs were observed in all mice. Although body weight was slightly increased in 3% MXD group than other groups, it was not significant. Hair regrowth began to be promoted after 14 days and appeared a distinct regrowth pattern in all animals by topical treatment of test compounds at 18 days. In particular, the topical treatment of bonogen shampoo or 3% MXD for 21 days to dorsal skin accelerated hair regrowth faster than DW or M shampoo. At 21 days, the hair regrowth promotion speed was in order of 3% MXD>BNG>M>DW. The bonogen shampoo or 3% MXD also promoted hair follicle elongation compared to the negative control. These results suggest that bonogen shampoo has hair growth promoting activities and may be useful for treatment of bald or alopecia.
