The aim of this study was to conduct a theoretical examination of the relationship between three factors - namely, the service failure type, the customer satisfaction, and the service recovery justice –, and to suggest some practical considerations for managers of beauty shops to improve the management of their shops. The results of this study demonstrate that a practical recovery system is required not only to respond to customers’ needs, but also to convert risks into opportunities by increasing customer satisfaction in highly risky situations of service failure. The findings also show that profit generation through an increase in customer satisfaction requires intermittent marketing efforts around service quality increase, as well as fair and active claim management in cases of service failures. Therefore, beauty service companies need to put service recovery strategies in place to be able to deal with service failures effectively. It is also worth noting that in events of service failures, maximum positivity in customers’ emotions can be achieved by front-line staff when they are able to observe customers’ emotional changes promptly and to respond to them actively and with appropriate authority.

This study investigated what applicants for department of Cosmetology have prepared before entering universities and how it influenced satisfaction after entering universities. Verified findings from these study hypotheses are summarized as follows. First, the hypothesis that application motive may affect university examination demonstrated that preference motive as a subfactor of application motive did not affect the examination. However, it had positive impacts on preference. Second, they hypothesis that application motive will affect department satisfaction found that preference motive as a subfactor of application motive showed negative impacts, yet it was rejected due to the absence of significance. However, it affected positively on preference influence. Third, the hypothesis that university examination will affect department satisfaction confirmed that school as a subfactor of university examination was rejected and private institute showed a positive influence. Therefore, this study intends to propose the following recommendation to activate cosmetics-related education in middle and high schools. Institutional support is indispensable to carry out a joint operation of special cosmetics programs between middle, high schools and universities along with active educational strategy in a single middle and high school.

The purpose of this study was to determine the potential of Clerodendrum trichotomum as a natural material for cosmetics by investigating the cytotoxicity and bioactivity of the ethanol extracts. The yield rate and phenol contents of ethanol extracts of Clerodendrum trichotomum were 3.85% and 53.266 mg/g, respectively. The electron donating ability was measured as 80.2% at 1000 μg/mL, suggesting that antioxidative activity increases as the density is increases. The inhibition rate at high density was similar with that of ascorbic acid, a control material. For the density of P. acnes, E. coli, S. epidermidis, and S. aureus, the longest ones were S. aureus (12 mm) in 1 mg/mL, S. epidermidis (15 mm) in 5 mg/mL, P. acnes and S. epidermidis (both 15 mm) in 10 mg/mL, and S. epidermidis (15 mm) in 20 mg/mL, respectively. The measurement of scavenging activity for the ABTS radical showed 97.264%, a value similar with those for Ascorbic acid and MTT assay measured by the survival rate of macrophage Raw 267.4 showed that the ethanol extracts of Clerodendrum trichotomum has no toxicity. The expression of iNOS decreased with the density over 100 μg/mL and the inhibiting effect for COX-2 was observed with the density over 300 μg/mL. These results showed that the ethanol extracts of Clerodendrum trichotomum has high potential as a raw material of natural cosmetics and this study is expected to provide fundamental date for the application.

This study attempted to investigate the hair-protection effects of Lens culinaris extract by the time and amount of its application during a heat perm through its great antioxidant activities. For this, testees were divided into two groups: P group (5%, 10% and 15% Lens culinaris extract added to the reducing agent) and J group (5%, 10% and 15% Lens culinaris extract added to the oxidant). Then, the following was analyzed with the hair: tensile strength, thickness, cuticle, components and ingredients. The results found the following: In terms of tensile strength, the P1 group was the highest with 153.19 ± 23.00, followed by the J1 group (124.80 ± 21.71). In hair thickness, the P2 group was 0.038 ± 0.009 mm while the J1 group showed results (0.040 ± 0.003mm) closest to healthy hair. In cuticle conditions, P1 showed 432.660 nm ± 12.283 while J1 was 427.880 ± 12.051 nm. In J1, some slight cuticle degradation and exfoliation were observed. Compared to the control group, however, J1 showed a relatively consistent cuticle and stable pattern. According to analysis of components, J1 was the highest with 9.17 Wt% while P1 was 9.13 Wt% in sulfur contents, which means that Lens culinaris extract makes up for sulfur. The said results prove that an addition of Lens culinaris extract during digital perms would reduce hair damage. In particular, the addition of 5% Lens culinaris extract to the oxidant appears to be more effective in hair protection.
