This study is a design haircut according to the head area division and slice line; the head area division is named the top and the bottom is named the bottom. The first head division is named G1 for center point - golden point - back point. The second division center point - Golden Back Medium Point - The next back point was named GBM1. The third division center point - back point - back point was named B1. This is a 0 degree natural angle, A line, parallel line, V line, slice line, and all the cut techniques were used as a Blunt technique. The upper part of the head was used for measurement, and the lower part of the head was used as a gradation 30 degrees, parallel line, but was excluded from the measurement. The volume, expansion, and weight were increased according to the division of head parts, and smooth texture and smooth texture were shown. In the case of A line, classical image and form appeared, and in the case of parallel line, ordinary image appeared, and in the case of V line, cute image and youthfulness appeared. The study on the division of the head region of the one-lining cut and the gradation cut, and the creative design cut applying the slice line, has been demonstrated and basic data are provided.
