Design Form of Graduation and Incremental Layer Cut according to Segmentation of Head Regions, Slice Line and Angle

Abstract

Purpose: This research investigated how changing the division of a head area affects design. Furthermore, this research aimed to understand the variations in design form based on the slice line, present a sample of the cut design, and provide basic data for haircuts.Methods: The upper head was divided in to three areas by from the center point to the golden back medium point-then ear back point, from the center point to the back point-then ear back point, and from the center point to the back nape medium point- then ear back point. The upper head angle was 45° and the slice line adopts A line, parallel line, and V line. The upper and lower head angles were 110°, 130°, and 150°.Results: A line and V line became more distinct toward the face line, while the parallel line appeared flatter. There was no weight line in the incremental layer cut, and there was no noticeable difference in the change according to the angle in the concave stretched shape. When dividing the head area, the length was shortened when the starting point of the upper part was placed upward and lengthened when it was placed downward. The medium gradient cut appeared on the edge of the weight without falling hair on the same line.Conclusion: A line exhibited increased volume, weight, and expansion, while V line showed a decrease in these factors but an increase in volume, rhythm, and vitality. A line was observed to be mature and thin, while V line was cute and sporty, and the parallel line was plain and neat. Even with the same slice line, the length varied based on the segmentation of the head region. The head division, slice line, and angle should be selected based on the customer's head shape, face shape, and taste.
