Nail-care services are growing rapidly. If causes for the increase in nail-care service consumption is diversion or self-satisfaction, we can speculate that consumers perform self-care through nail-care services. Nail-care-service consumption should be allowed to increase because of the positive psychological effects such as improving mood or alleviating depressed emotions. Moreover, the psychological effects of nail-care services differ according to consumers’ tendencies. Therefore, this study divides the types of consumers, to investigate whether there is a difference in the psychological effects of nail-care services depending on the types. This study used the questionnaire survey method. Results of the study revealed that the sub-factors of self-esteem, extracted as two factors, were “personal self-esteem” and “social self-esteem”. Consumers were classified according to the sub-factors of self-esteem into four groups. There were differences in the psychological effects of nail-care services according to these four groups. It was found that all groups had psychological effects above the average value. This result indicates that only the degrees of psychological effects differ in accordance with the types of self-esteem, and that psychological effects generally play a large role in all types. Since psychological effects were positive for everyone regardless of their self-esteem, utilizing nail-care services considerably reduces the depression and anxiety of modern people. Nail-care services expected to become the basis of the nail therapy field.
