This research is the hair damage as treating a permanent wave before and after that is compared and analyzed the change of physical and mechanical properties. This is the survey of women's hair in 20 years old. On the basis of this we would like to analyze a extend of hair damage. Also, we would to show a basic data for hair damage prevention and hair improvement to keep the beautiful and healthy hair. The conclusion is as follow. : The swelling degree after the treatment was found to be greater than before permanent wave treatment. For the formational characteristics wave, untreated hair certainly had more elastic S curl wave than damaged hair in all the permanent wave treatments, and damaged hair and extremely damaged hair had less elasticity and had saggy S curl wave. The protein permanent and soft permanent wave had thicker, gorgeous, and better elastic wave than the regular permanent wave and direct heating permanent wave in all the hair condition. As the degree of damage on hair got greater, the tensile strength dramatically decreased and as the degree of damage got greater, the elongation was great as well. For treatment method, direct heating permanent wave showed the greatest effect, causing the most damage.

Human hair could be damaged by various physicochemical conditions and treatment. Permanent and decoloring treatment were the most serious factor on hair damage. The new permanent wave lotion containing Permeation enhancers such as Cremophor EL, Transcutol and propylene glycol based on cysteine permanent wave lotion were prepared. Efficiency of permanent wave and hair damage following pH of permanent wave lotion and addition of permeation enhancer were investigated. PH of solution, wave efficiency, loss of protein from hair, morphology of hair by SEM and solubility of alkaline solution were evaluated. The addition of Cremophor EL and Transcutol with ethanol increased permanent wave efficacy and decreased hair damage effectively. They diminished permanent wave lotion's pH and augmented permanent wave lotion's penetration compare to cysteine permanent wave lotion. new permanent wave lotion containing permeation enhancers such as Cremophor EL could be a good candidate for a new permanent wave lotion.

Diversification and individualization are pursued to fulfill the increasing human desire for beauty. There are many methods to change human appearances; of these, a permanent wave is often applied to improve beauty. A permanent wave uses physical and chemical methods to break and reform the bonds of natural hair. Thus, research into the optimized conditions for permanent waves is necessary to minimize hair damage and improve the efficiency of the treatment. The object of this study is to examine the effect of varying the alkalinity (8%, 12%, and 16%) of the permanent wave treatment on the wave efficiency, degree of hair damage via tensile strength, and degree of hair protein release. The results indicate that the treatment with the highest alkalinity (16%) is more effective than that with 8% alkalinity; however, the degree of hair damage when treated with the 16% alkalinity wave is higher than with the 8% alkalinity wave. Additionally, hair proteins increasingly dissolve with increasing alkalinity of the permanent wave.

The goal of this study is to provide beauticians with the fundamental material to use effectively heat permanent wave in beauty industry as well as their customer's satisfaction. It carried out an experiment with damaged hair of a woman in her late twenties to investigate the change of physical and morphological characteristics by its water content when performing heat permanent wave. After spreading 0g, 1g, 2g, 3g, and 4g of water on damaged hair respectively, heat permanent wave was treated and the change of hair was observed. The change of physical characteristic was compared through permanent wave form of hair, tensile strength and elongation. The change of morphological characteristic was observed through Scanning Electron Microscope(SEM) and Transmission Electron Microscope(TEM). The result of experiment on the physical specificity revealed that permanent wave form was the most ideal when the water content was 2g, also 3g. Though the materials with much moisture content formed the results were not satisfied. The material with 0g of water content didn't make the wave. In terms of tensile strength and elongation, tensile strength was generally reduced as per the damaged degree of hair. On the contrary, elongation was increased. It observed the changes of morphological characteristic that the damage on hair cuticle was deepen, as its moisture content was decreased, and cuticle's surface was worn away. The observation of fine structure on hair section by transmission electronic microscope also certainly showed the result that damaged hair having experience with chemical treatment had got much damaged to hair cuticle as well as hair cortex. Generally chemical treatment makes hair damaged. Under consideration of this aspect, the ultimate goal of this thesis is to minimize the damage of hair caused by chemical treatment and get the satisfaction on the hair style. According to the result of experiment, the damaged hair whose moisture content was 3g showed the best permanent wave form.

본 연구에서는 콜라겐의 처방이 퍼머넌트웨이브 시술시 미치는 영향을 알아보기 위하여 정상모에 콜라겐을 농도별 처방한 퍼머넌트웨이브제로 퍼머넌트웨이브를 시술한 후 모발에 컬의 형성력, 굵기 관찰, 인장 강도, 메틸렌블루 흡광도, 수분 감소량 등의 변화를 측정하여 비교분석하였다. 결론적으로 퍼머넌트웨이브제의 콜라겐 처방 여부에 따라 모발의 굵기, 모발의 인장강도, 모발의 수분 감소량, 흡광도가 처방하지 않은 환원제에 대비하여 감소하였으며, 처방된 콜라겐의 농도가 증가할수록 모발의 손상도가 줄어드는 결과를 보였다. 그러나 콜라겐의 농도의 크기가 커질수록 퍼머넌트웨이브 시술시 컬의 형성력이 떨어지는 결과가 나타났다. 그러므로 퍼머넌트웨이브 시술시 모발의 손상도를 줄이기 위한 콜라겐 처방 농도는 2%가 적당하였다.

Public interest in healthy hairs gets growing as damaged hairs are seen more frequently with the generalization of heat permanent waves. For this study, experiments have been conducted to understand the influences on the changes in physical and morphological features of wave forms and damaged hairs, by collecting virgin hairs from the women in their mid-20's, who had not experienced chemical applications, and by dividing the applications of heat perm hair treatments, PPT(for pre-treatment) and LPP(for post-treatment), into the pre-treatment, the post-treatment, the pre & post-treatment, and the non-treatment. For the wave formations, curl waves were investigated by the bare eyes using the pictures taken by a digital camera. For the comparison of physical features, the experiments of tensile strength and elongation were done and their mean values were found. For the observations of morphological features, the pictures were taken by SEM for comparison. As for the findings, regarding the curl wave shapes of hairs, the most even and elastic S curl was formed in the case of non-treatment. In the physical features, both of the tensile strength and elongation showed a decreasing tendency in line with the hair damage levels, and the case of the pre & post-treatment indicated the tendency most similar to the control group. In the morphological features of the cuticle, observed with an SEM, the pre-treatment showed the higher possibility of reducing the cuticle damages than the post-treatment did. LPP was found to play the role of protective membrane for the post-treatment, and the pre & post-treatment turned out to reduce most effectively the cuticle damages.

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.

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.
