This study attempted to find the optimum amount of manuka extract ingredient with hair treatments in different manuka extract contents and examine its bleached hair protection effects. For this, the tensile strength and moisture level of the damaged hair were measured. In addition, hair conditions were analyzed, using SEM and FE-SEM. In terms of protection of bleached hair, all experimental groups (M1, M2, M3) were more effective than the control group (no manuka extract added) in tensile strength, moisture level, hair thickness and cuticle conditions. In particular, 'M3 (3% manuka extract)' revealed the largest hair protection effects. The above results confirm that Manuka extract-added hair treatments would be useful in protecting damaged hair as well as scalp as a cosmetic material. It is anticipated that there would be further studies on diverse chemical treatments with a much wider variety of samples.

This study was carried out to investigate the hair protection effect of fermented black soybean extracts. The morphological characteristics, tensile strength and constitutional changes of the hair were analyzed and compared when the hair was chemically oxidized and then treated with fermented black soybean extract. As a result, treatment of oxidizing agent on virgin hair caused damage on the cuticle layer of the epidermis and decreased in tensile strength of hair from $14.32{\pm}0.83g/cm^2$ to $12.32{\pm}0.79g/cm^2$. FT-IR analysis showed the peaks at 1,077, 1,041, and $801cm^{-1}$ of the hair treated with oxidizing agent were increased compared to peak values of virgin hair, indicating that cystein in hair was decreased which is crucial to disulfide bond between keratin. On the other hand, when the damaged hair is treated with the fermented black soybean extract, cracks in the cuticle layer of the epidermis were filled, tensile strength was restored to $14.27{\pm}0.96g/cm^2$ and the ratio of oxidized cysteine in hair was decreased. These results suggest that the fermented black soybean extract is worthy of further investigation as a protective material for hair damaged by oxidizing agents.

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 this study is to maintain healthy hair by treatment. Frequent permutations cause a lot of damage to the ends of the hair, and use permant wave pre- and post-processing agents step by step to protect the damaged ends of the hair. The Ginkgo Biloba Leaf Extract used in this study are effective for anti-bacterial, antioxidant, anti-cancer blood circulation and skin moisturizing. This extract was soaked in 1 perm paper and 2 perm papers and wound, and then the cuticle, tensile strength and wave formation rate were investigated. An average comparison analysis was conducted, and when the ginkgo leaf extract was applied to two perm paper sheets, the permanent hair tip showed the highest hair improvement effect.

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.

Hair manicure is usually and widely operated in the area of hair-dyeing by the reason that acidic hair color is less damaged and more stable than other chemical color treatment. However, there is no an in-depth study to prove them. This study purposes to provide basic resources for effectively using products of hair manicure by experiments on Physical Properties of Hair. Hair of one healthy woman in mid-20's, Level 4, was sampled for experiments. For the tests, hair samples were classified by the frequency of hair manicure treatment The control group(a), once treatment(b), twice(c), three times(d), four times(e) and five times(f). The results were measured with Scanning Electron Microscopy(SEM) and Tensile Strength and Elongation test. The lower Values of Tensile Strength according to repeated hair manicure treatment. Elongation is not affected by the frequency of hair manicure treatment. There was no remarkable change of hair surface in once(b) and twice(c) treatment. The change of hair surface which was able to judge by cuticle layers looseness, tunics and the transformation of cuticle cell were observed in the hair samples operating more than three times(d) of hair manicure treatment.

This study aims to propose a method to reduce hair damage after investigating the following: the factors which vary depending on hair treatment conditions; the degree of hair damage in the bleached sample; and an analysis of the effects of a perm on wave formation. To determine the effects of these treatment types, hair bleach was mixed with the hair treatment, and hair damage and formation of permanent waves were examined. Using a scanning electron microscope, in addition, morphological changes were analyzed and the following results were obtained: After mixing natural powder(2.5g) and hair cream(2.5g) and bleaching the mixture, it was compared to the scale structure of untreated hair. When 5g of natural powder was mixed and bleached, a clear layer was observed among cuticle scales, showing the effects of hair treatment. Therefore, this confirms that the effects of hair treatment were most notable when grain powder was mixed with hair cream. Once hair is damaged, it is almost impossible to regain its original state. When chemical agents are used, therefore, it is important to consider the possible hair damage they cause.

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.

Modern people express their beauty through hair coloring, but hair can be damaged by repeated chemical treatments. In order to increase the durability of dyeing and minimize the hair damage, in this study, the acidic amino acids including aspartic acid (Asp) and glutamic acid (Glu) were used to post-treat hair during hair coloring. The post-treatment with 0.75% Asp and Glu solution was carried out at room temperature for 20 minutes after dyeing bleached hair with cherry red and blue silver colors. After repeated shampooing of 1, 5, 10, 15, 20, and 25 times, L^*a^*b^* value of dyed hair was measured to confirm the dyeing durability, and the changes in tensile strength, porosity, and surface properties of the hair were also analyzed to determine the condition of the hair. In the case of cherry red and blue silver staining, the Asp and Glu experimental group showed higher color persistence than the control group, and the Asp and Glu experimental group showed higher tensile strength, lower porosity and smooth surface properties than the control group. In particular, the Asp test group showed superior color persistence and lower hair damage than the Glu test group. This study, therefore, if damaged in dyeing and bleaching in the field of hair after treatment with asp glu a combination of hair cosmetics in the development of basic data look forward to be.
