Stained and discolored hair will be damaged by the shampooing, daily UV disposal, and the use of hair dryer. Thus many studies about the effect of various natural substances on the re-secure the skin and scalp are recently reported. This study was carried out to investigate the effect of green tea (Camelloia sinensis) seed oil on colored (dyed) and decolored (bleached) hair. The beneficial effects of green tea seed oil are already well known, but little research has been done about the hair treatment and fade-resistant effect. Dyed and bleached hair was pretreated with green tea seed oil to determine the tensile strength and elongation of the hair, to analyze the hair surface using SEM, and to compare the color fade using spectrocolormeter. The results showed that the tensile strength increased with green tea seed oil pretreatment samples for virgin, dyed, and bleached hairs. Elongation showed the reverse results showing the presence of hair treatment effect. The results of the surface pre-treatment in all groups analyzed by SEM, the hair cuticle became sharper, so coating effect were identified with all samples. The value of the $L^*$, $a^*$, $b^*$ decreased with washed hairs damaged by UV irradiation and the values were decreased also in dyed and bleached hair. In summary, green tea seed oil prevent reinjury to the heat and UV rays for colored and decolored hairs. Cosmetic practice effects of the oil were identified in the field to be appropriate to the customer's skin and scalp that natural cosmetic oils would like to offer.

Luffa cylindrica Roem (sponge gourd) belongs to the Cucurbitaceae family and has been cultivated as an ornamental plant in Korea. Recently, its cultivation area has been increased with an increase in demand for it as an ingredient in cosmetics, herbal medicines, and health supplements. We analyzed inorganic components of sap collected from land race sponge gourds. We also measured antioxidant enzyme activities and antimicrobial activities of the plant, seed, and sap to examine functional properties of sponge gourd. The sap of the sponge gourd contained high levels of K, Ca, P, and Mg, with the most abundant mineral in the sap being K ($470mg{\cdot}L^{-1}$). The amounts of Ca and Mg were 2 and 1.7 times more than those found in cucumber (Cucumis sativus), respectively. Ascorbate peroxidase was more active than catalase and superoxide dismutase in various plant parts of sponge gourd. Antioxidant activities were much lower in stems than in other plant parts such as leaves, roots, flowers, fruits, seeds, and sap. In addition, sap showed a very low level of antimicrobial activity against two food-borne pathogens, Vibrio parahaemdyticus and Propionibacterium acne, and none against the other eight tested food-borne pathogens. Antimicrobial activities against Candida albicans and Malassezia furfur, which causes dermatitis, appeared to be higher in sap than in other parts of sponge gourd plants. Overall, the antimicrobial activity against Malassezia furfur appeared to be higher than against Candida albicans.

The biological activity of hot water extract from Ecklonia cava Kjellman (ECE) was investigated to assess antioxidative, anti-skin aging, and nitrite scavenging abilities, as well as alcohol metabolizing activities. Antioxidant activity of ECE was measured by using 2,2-diphenyl-1-picryl-hydrazyl (DPPH) radical scavenging activity and superoxide dismutase (SOD)-like activity. DPPH radical scavenging activity and SOD-like activity of ECE increased in a remarkably dose-dependent manner, and were about 91.4% and 75% at 1 mg/ml, respectively. The xanthine oxidase inhibitory activity was indicated to be about 70% at 1 mg/ml of ECE. Nitrite scavenging ability of ECE showed to be 93.6% at 1 mg/ml and pH 1.2. The influence of ECE on alcohol metabolism was demonstrated through the generating activity of reduced-nicotinamide adenine dinucleotide (NADH) by alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH). The facilitating rate of ADH and ALDH activity by ECE was 167.2% and 334% at 10 mg/ml, respectively. In addition, tyrosinase and elastase inhibitory activities of ECE were 58% and 72% at 10 mg/ml, respectively. These results indicated that ECE has valuable biological attributes owing to its antioxidant, nitrite scavenging, alcohol metabolizing, and elastase and tyrosinase inhibitory activities.

In the rapidly changing 21st century, image management has become more important. Under these circumstances, as a lot of hair colors and beaching agents are used to create diverse hair colors, hair damage resulting from frequent chemical hair coloring has been inevitable. This study investigated how to reduce morphological changes in hair and hair damage after dividing hair into healthy hair('Group A') and damaged hair('Group B'), using the following bleaching agents: basic bleaching agent(a), beaching agent diluted with water(b), oil ingredient-added bleaching agent(c), water-shampoo mixed bleaching agent(d). The results found that even though hair damage can be prevented by a bleaching agent diluted with a mixture of diverse additives, there were better effects on hair texture in both 'Group A(4.83)' and 'Group B(4.41)' at a sensory test when hair was bleached with an addition of Camellia oil, according to blinded experiment, in particular. As a result, hair damage could be reduced. Therefore, this study expects that hair bleaching with an addition of Camellia oil to the mixture of a bleaching agent would bring the development of diverse new materials which can minimize hair damage as well as regulate hair brightness and make a contribution to the development of cosmetology market.

Many people of all ages wish to have lighter skin for cosmetic reasons, and natural products attract more attention than chemically synthesized compounds. Uncaria rhynchophylla is widely used in Asia as a traditional herbal medicine. In order to find novel skin whitening agents, the present study evaluated the antioxidant activity and potential tyrosinase-inhibiting properties of U. rhynchophylla. Specifically, this study analyzed the antioxidant capacity of a 70% ethanolic extract of U. rhynchophylla as well as its effects on tyrosinase activity and melanin synthesis. Total mRNA levels were examined using reverse transcription polymerase chain reaction. The results revealed that U. rhynchophylla extracts exhibit great antioxidant capacity and significant levels of polyphenol and flavonoid compounds. U. rhynchophylla extracts can also powerfully inhibit tyrosinase activity. This same capacity was observed in melanoma B16F10 cells; that is, U. rhynchophylla extracts suppressed intracellular tyrosinase activity and reduced the amount of melanin in treated cells. In addition, a 1 mg/ml concentration of U. rhynchophylla extract significantly reduced the mRNA expression levels of tyrosinase. U. rhynchophylla extracts decrease tyrosinase and inhibit melanogenesis in B16F10 cells. This finding suggests that U. rhynchophylla has great potential as a natural whitening agent in skincare products.
