Recipient Area Hair Direction and Angle in Hair Transplanting

In the 2004 paper, the author highlights the critical role of replicating natural hair direction and angle in hair transplant procedures to achieve natural-looking results and prevent damage to existing hair. The paper suggests that multi-follicular-unit grafts can create a higher perceived density when placed in the same direction as the original hair. Techniques such as using coronal grafts for certain hair styles and sagittal grafts for dense packing are discussed, along with the "shingling" effect that enhances coverage. The author concludes that following the natural hair direction and angle, especially when using double or triple follicular units, does not decrease hair survival, indicating the success of these meticulous techniques in hair transplantation.
