The purpose of this study was to investigate the effects of home care hair treatment characteristics and frequency on hair during permanent wave treatment. The hair treatments distributed on the market were classified into cationic surfactants and silicone oil. Hair treatment was performed 5 times, 10 times, 20 times differently according to the frequency of use, and hair permanent wave was performed. The hair thickness, tensile strength, epidermal observation using SEM, and hair component analysis using EDS were performed as experimental methods. The results of the experiment showed that the natural-derived ingredient was the main ingredient, and the cationic surface activity and silicon oil-free product group had high hair protection effect. Therefore, the product group using natural ingredients should be further researched and developed, and the study on the method and frequency of use of products with irritant chemical ingredients should be conducted.

The purpose of this study is to present basic data for hair color work plans that can consistently produce hair color design products for designers through analysis of gradient techniques among hair color design techniques. The research method was to select 10 photos of women that appeared in mass media from 2022 to September 15, 2023, extract color chips and RGB values using the Eyedropper Tool in Adobe Photoshop CS6, and convert the RGB values of the color chips into Munsell Conversion ( The data was converted into HV/C values of version 12.1.13a). Based on the extracted data, the gradient hair colors of female pop stars were analyzed by displaying the data on a color scale. As a result, in the I.R.I color scheme image scale, the image of female pop stars was more hard than soft. In addition, it was confirmed that the focus was on static rather than dynamic. Color matching images according to hair color were extracted with adjectives such as noble, decent, elegant, and subtle. Three hairstyles were created using this theme.

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.

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.

In this study, we conducted a compositional analysis of five darkening shampoos available in the South Korean market and evaluated their active ingredients and safety based on the analysis results. GC-MS analysis was employed to identify the main components of each shampoo, revealing discrepancies between the detected compounds and the ingredient lists provided by the manufacturers. These differences are interpreted as being due to the limitations of the GC-MS analysis and the volatility of certain compounds. Further investigations were carried out to explore compounds potentially contributing to hair darkening. However, it was not definitively concluded that these compounds are directly involved in the hair darkening process. It is speculated that they may enhance hair care product performance and offer additional benefits to hair, or improve product texture, stability, or preservation. Additionally, the GC-MS analysis identified several compounds with potential safety concerns, necessitating caution when used as cosmetic ingredients.

Chemically damaged hair is vulnerable to external stimuli in daily life due to the weakened physical properties of the hair strand itself. The purpose of this work was to determine whether chemical conjugation between hair keratin proteins restores tensile strength and thus results inpreventing further deterioration under repeated combing. A model damaged hair tress was produced by a typical perm-process. Then, it was internally crosslinked by the bifunctional crosslinker (3-aminopropyl)triethoxysilane (APTES), via both silane coupling and carbodiimide chemistry. Physical properties, including tensile strength, Young's modulus, and plateau stress, were measured to verify the effect of internal crosslinking, and the existence of crosslinking was verified by Fourier transform infrared (FT-IR) spectroscopy. The degrees of hair breakage and split ends were evaluated by repeated combing-drying tests. Physical properties of chemically damaged hair were restored by internal crosslinking. Successful crosslinking of APTES via both silane coupling and carbodiimide chemistry was verified by FT-IR spectra. Prevention of breakage and split ends after repeated combing with heat was observed. Human hair can be weakened by chemical damage including perm-processing, so restoring such properties is a major issue in the hair care industry. This work shows that internal crosslinking of damaged hair via chemical conjugation would be a potent method to restore the healthy hair.
