In this study, in the era of prosuming, we compared the aspect of value provided by self-nails to consumers and the aspect of value provided to consumers by professional nail services provided by existing experts, and derived key elements of each nail service. In order to achieve the purpose of this study, established a research model and analyzed the responses of a total of 293 people through the questionnaire method. The main research results of this study according to the above research objectives and methods are summarized as follows. First, as a result of examining the effect of service factors of professional nail service on consumers' value perception, reliability and communication factors had a statistically significant positive (+) effect on emotional value, and the influence of reliability was stronger. On the other hand, reliability had a statistically significant positive (+) effect on economic value. Second, as a result of examining the effect of self-nail service factors on consumers' value perception, rationality and convenience factors had a statistically significant positive (+) effect on emotional value, and the influence of rationality was stronger. On the other hand, diversity, rationality, and convenience all had a statistically significant positive (+) effect on economic value, and rationality had the strongest influence as well. Based on the above discussion, the professional nail service should recognize the importance of maximizing the professional competence of a nail artist perceived by customers, and honing his/her competence as a nail care expert according to the changes of the times. Also for self-nail service, a more convenient and safe product should be released for the procedure and post-procedure detachment so that a rational choice can be made in consideration of the customer’s procedure, personal hygiene, and health. Also, it is thought that a priori demand survey to understand consumer needs should be followed one after another.
