TLDR Dr. Walter P. Unger suggests that copying a person's natural hair direction and angle during transplants leads to a more natural and fuller appearance.
In the 2004 document, Dr. Walter P. Unger presented a technique for hair transplanting that emphasizes the replication of the patient's natural hair direction and angle to achieve a natural appearance and maximize perceived hair density. He discussed the variability of hair patterns, similar to fingerprints, and the importance of observing even vellus hairs to determine the original hair growth patterns. Unger recommended the use of multi-follicular-unit grafts for creating a denser look and described the "shingling" effect where the orientation of grafts enhances coverage. He also noted that while coronally placed follicular units may cause more or less vascular damage than sagittally planted ones, the overall visual impact of hair density is improved when the natural growth pattern is followed. The document did not report on a study with participants but was based on Unger's clinical experience and observations.
