This study was conducted to empirically examine the impact of service quality on business performance in one-person hair salons, where customer satisfaction and relationship maintenance are critical in the continuously growing beauty service industry. The research targeted 231 male and female customers in the Gwangju and Jeonnam regions who had experience using one-person hair salons. Data were collected through a Google Forms survey conducted from September 11 to October 6, 2024. The collected data were analyzed using frequency analysis, factor analysis, reliability analysis (Cronbach’s α), descriptive statistics, correlation analysis, and multiple regression analysis.The key findings of this study are as follows. First, as a result of identifying the components of service quality in one-person hair salons, three factors—reliability, tangibility, and empathy—were derived, while business performance was classified as a single factor. Second, the service quality of one-person hair salons showed a statistically significant positive effect on business performance (F=267.700, p<.001). The overall explanatory power was 54.6% (F=91.112, p<.001), and the influence of each subfactor was confirmed in the order of tangibility (β=.388, p<.001), empathy (β=.277, p<.001), and reliability (β=.169, p<.05). These results empirically demonstrate that the service quality of one-person hair salons has a meaningful impact on business performance, suggesting that in such salons, service quality management is a key factor directly linked to performance—more so than marketing resources or external personnel.
