The 21st century, which can be called the globalization and the information age, shows a tendency to create various designs by mixing traditional and modern culture in the flow of design. Especially, in the Korean traditional culture, Danchong pattern (motifs) is an artistic material with the emotion of the nation which possesses the visible formative characteristics and distinctive beauty on Yin-Yang and the Five Elements of the oriental people. For this reason, active research is being carried out on Danchong currently in various fields including fashion, art, beauty industry, and education. However, specific research on hair design is quite limited and inadequate. Accordingly, in this research, we have considered on hair-by-night and Danchong pattern theoretically, and produced our works on the basis of the types of pattern to be applied to hair design and their symbolic meaning. Of basic motifs of Dangchong pattern, we have selected phoenix motif and butterfly motif among animal motifs and chrysanthemum motif among plant motifs and produced creative hair-by-night works. In this thesis, we have presented a new design of hair-by-night by reinterpreting Danchong creatively to agree with modern sensibility.
