Hairstyle Form Variations by Head Division and V-Section Lines with Graduation and Same-Layer Cuts

Purpose: This study aimed to provide foundational data for haircut design by analyzing style and length variations resulting from the application of a V-section line after head division, combined with graduation and same-layer cuts.Methods: All haircuts were set to a length of 5 cm at the nape point (N.P.) with the V-section line applied. In the occipital region, low-, medium-, and high-graduation cuts were combined with same-layer cuts. A total of 16 combinations were created to evaluate style variations. Post-cutting, length changes were measured at the N.S.P., B.P., T.G.M.P., E.P., S.P., T.P., and C.P.Results: The design line, weight line, and silhouette exhibited distinct changes depending on the combination of frontal and occipital cutting styles. The V-section line further generated diverse outline variations even under identical conditions.Conclusion: The study demonstrates that the combination of haircut styles along the V-section line is a critical factor in determining variations in the weight line, outline, and silhouette.
