Purpose: This study aims to provide fundamental data for two-block haircut design by empirically analyzing changes in haircut styles. The study sets the hair length at the nape point(N.P.) to 10 cm and applies parallel lines while dividing the head into upper and lower two-block sections. Graduation and same-layer haircuts are then applied in combination to examine the resulting style variations.Methods: The head was partitioned into two blocks with parallel lines and applied a combination of graduation and same-layer haircuts. The hair length was set at 10 cm from the N.P., and the position of the two section partitioning was determined at +1 cm above the side point(S.P.), using the golden back medium point(G.B.M.P.) as the reference for dividing the upper and lower sections. The lower and upper sections were assigned different combinations of low graduation, medium graduation, high graduation, and same-layer cuts. The head treatment angles were applied, and a total of 16 haircut variations were empirically analyzed to observe changes in form and hair length.Results: The application of parallel lines and the combined use of graduation and same-layer haircuts in both the lower and upper sections after two-block partitioning of the head resulted in diverse two-block haircut styles with distinct changes in form and hair length. These variations demonstrated the effect of two-block partitioning on haircut styling.Conclusion: The two-block partitioning of the head effectively expressed three-dimensional graduation and layered forms, emphasizing weight, volume, and curved shapes. It was concluded that various haircut designs can be achieved by considering the shape of the head, face lines, facial structure, fringe proportions, hair length, sectioning position, and treatment angles.
