Hairstyles are important for many women in visual attractiveness. However, it is difficult to objectively judge by themselves which hairstyle suits for them. Previous study has reported that circular-based complexity of psychological potential field (PPF), which can be calculated on digital images, indicates goodness of impressions for facial shapes. In this paper, we apply some complexities of PPF, including the previous complexity, to facial images to investigate whether good hairstyles for facial impressions can be quantified. Here, with constraining several facial components, subjective evaluation and objective evaluation have been compared by correlation analysis. Subjective evaluation adopts a paired comparison method, and objective evaluation adopts several shape analyses of PPF produced from each facial image. The results show a necessity to evaluate PPF with the gender separated. Moreover, some three-dimensional complexities of PPF indicated a certain effectiveness to assess good impression for hairstyles.
