The present study attempted to classify the type of beauty salon services using Kano model, and to analyze Timko’s customer satisfaction and potential customer satisfaction improvement (PCSI) index. In this regard, a survey was performed among 281 customers of beauty salons in Gwangju Metropolitan City. For data analysis, first, the customer requirements were classified according to Kano’s two-way quality model. The collected data were analyzed through frequency analysis, and using Microsoft Excel 2007 and SPSS 18.0. From the Kano model, 3 attributes were derived pertaining to the quality of beauty salon services, namely attractive quality, one-dimensional quality, and must-be quality. When both better and worse indices were analyzed, the former was the highest in ‘quick response to customer complaints’ while the latter index was the highest in ‘hairdressing services and service professionalism’. In regard to the PCSI index of the quality of beauty salon services, ‘quick response to customer complaints’ was the most important. It was anticipated that when this requirement is met, customer satisfaction would reach the highest level. Next comes ‘sincerity towards customers’ in the PCSI index. It was confirmed that when this requirement is met, customer satisfaction will increase further.
