Spectroscopic evaluation of hair chemical damage was performed by SEM/EDS, CLSM, and FT-IR spectroscopy. In SEM/EDS, hydrogen peroxide treated hair showed the loose packing of surface scales, lower ratio of sulfur element and higher ratio of oxygen atom. In the optical single section by using CLSM, high fluorescent intensity appeared in untreated hair. However, in case of treated hair, low fluorescent intensity appeared. This results the aromatic amino acids which can be autofluorescent were more abundant than bleached hair. FT-IR spectra showed that cysteic acid band intensity was increased by performing the bleaching treatments. These results indicate that the oxidative damage cleaves the S-S bond and results in the lower working force of hair fiber.

This study attempted to investigate the effect of improving damaged hair by preparing a hair improving agent with basil oil and applying it to damaged hair. An experimental material was added to a perm base agent containing 0 g, 3 g, 6 g, 9 g of basil oil to prepare the preparation. It was applied to sample hair bleached at 8 levels with the prepared formulation. Each sample and damaged hair were measured and analyzed. The measurement method measured tensile strength, absorbance and gloss using methylene blue to determine the effect of improving maternal quality. Statistical analysis was conducted on the reliability of the study results. Studies have shown that all samples with basil oil have higher tensile strength than damaged hair. As a result of the absorbance analysis using methylene blue, it was found that the absorbance was lower than that of damaged hair in all samples. Gloss measurement showed that all samples showed increased luster compared to damaged hair. In conclusion, basil oil was found to improve damaged hair. In the future, research on various types of oil and research methods is needed.

모발(human hair)은 양모섬유와 마찬가지로 시스틴을 많이 함유하고 있는 섬유상 케라틴 단백질로써, 두부(頭部)를 보호할 뿐만아니라 신체에 필요하지 않는 중금속을 체외로 방출하는 기능을 지닌 신체의 일부분이다. 또한 모발은 미(美)와 관련하여 가장 관심을 가지는 부분이며, 다양한 방법으로 모발에 변화를 주어 신분을 표시하거나 자신의 미적 표현을 하고 있다. 퍼머넌트 웨이브는 모발에 형태학적 변화를 주는 유효한 수단이며, 염색과 탈색 등은 색상 변화를 주는 중요한 수단이다. 본 연구 에서는 모발을 산성염료로 염색할 때 염색성을 향상시키기 위하여 염색보조제로써 벤질알콜 등을 첨가하여 염색할 때 염색된 모발의 염착량, 보습성, 단백질 유출성, 주사전자 현미경 관찰을 측정하여 다음과 같은 결과를 얻었다. 1) 염색시간이 길어지고, 염색온도가 높아질수록 모발에의 염착량은 증가하며, 특히 벤질 알콜을 첨가하여 염색하는 경우에는 빠른 시간내에 염착평형에 도달하고 비교적 낮은 염색온도에서도 높은 염착량을 나타내었다. 2) 이와같은 용매 첨가의 효과는 염액에 계면활성제와 함께 첨가하여 염색하면 나타나지 않았다. 3) 염색시간이 길어질수록 모발의 보습성은 열악해지지만, 벤질 알콜을 첨가하여 염색하는 경우에는 오히려 보습성이 증가하였다. 또한 염색시간이 길어지면 모발의 단백질 유출성은 증가하지만, 벤질 알콜을 첨가하여 염색하는 경우에는 오히려 단백질 유출성이 감소하였다. 이와같은 결과는 벤질 알콜을 첨가하여 염색하는 경우에 모발의 손상이 적다는 것을 의미한다. 4) 모발의 손상정도에 대한 주사전자현미경의 측정결과는 벤질 알콜의 첨가여부에 따라 큰 차이를 보이지 않았다.

Appearance management through hair beauty forms the basis of the beauty industry, while permanent waves using heat are often used in hair salons, but hair damage due to thermal permanent wave treatment is an inevitable reality. Therefore, this study was conducted for the purpose of presenting an efficient method for thermal permanent wave that can further increase hair wave formation ability and minimize customer's hair damage. After collecting virgin hair from the occipital region, thermal rod pretreatment and thermal permanent wave treatment were performed, and hair roughness analysis and 3D-image were studied using an Atomic Force Microscope. As a result of the study, both the average roughness (Ra) and the ten point average roughness (Rz) were calculated as 223 nm and 853 nm for 4 sections, respectively, showing the highest values. Although the number of samples of the experimental data is limited, the wave forming power can be further increased through this study, and it is expected that it will be practically possible to propose an objective method for thermal permanent wave that can minimize hair damage as well as protect the cuticle of the customer's hair.Judge.

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.

In the social atmosphere where the importance of appearance is increasing day by day, efforts and desires of modern people are becoming more active and diversified, and the beauty beauty industry is gradually becoming more specialized and specialized due to these effects. Hair damage is inevitable due to the excessive permanent wave or hair coloring of modern people. However, as the hair is damaged, the cuticle peels off and falls off, and the tensile force decreases and the satisfaction after hair styling or perm decreases relatively. Therefore, it is necessary to manage damaged hair, but since artificial synthetic products occupy most of hair treatment agents on the market, it is necessary to develop a hair treatment product containing antioxidants useful for the human body. In this study, the effect of maple leaf extract on the mechanical change of colored hair was analyzed to investigate the potential of maple leaf extract as a hair treatment agent to improve damaged hair and improve hair health. It is considered that this study will be used as basic data for the development of hair beauty products using natural products in the future.

The structure of the coacervate can dramatically influence deposition on the hair. The purpose of this study was to investigate the effect of coacervate with a relatively fine and uniform structure on the surface properties of hair and its influence on hair damage. In this study, coacervates of different sizes were explored in 10% shampoo solutions; one solution contained coacervates with non-uniform sizes ($10-300{\mu}m$ average), and the other solution formed a coacervate with a fine and uniform ($1-3{\mu}m$) structure. To study the effect of shampoo on the physical properties of hair and damage to the hair, the hair breakage characteristics, color changes, friction properties, lipid contents and hair surface were examined after using two different types of shampoo. The results clearly show that the relatively fine and uniformly sized coacervate was evenly deposited over the surface of the hair. As a result, the coacervate system can substantially influence the surface properties of the hair such as hair friction, breakage characteristics, and color. The frictional force was dramatically reduced. The use of a fine and uniformly sized coacervate can notably improve hair surface properties. Consequently, hair breakage decreased, and the effect of the coacervate on hair damage was remarkably high.

The current study aimed to find the effects of hair treatment with shea butter on bleached hair and hair protection. The agent for hair treatment with shea butter was developed in different concentration levels (0%,1%,3%,5%) for experimentation. After applying the agent to bleached hair, hair samples were evaluated as follows. Increase in hair thickness was highest in the hair sample that had 5% of shea butter. The amount of amino acids was also highest in the hair sample that contained 5% of shea butter. Comparing the difference of the surface color, hair sample with 5% of shea butter showed low level of L⁎ while the level of a⁎ value that reflects the redness was high and the level of b⁎ value that reflects yellowness was low. Observation through the scanning microscope confirmed the positive effects by showing smoother surfaces in the sample with shea butter than in the bleached hair. This study showed shea butter is considered to be cosmetics to protect damaged hair by bleaching.
