Figure 1.

(a) Scalp hair grafts have longer intradermal course and one can easily harvest follicular units having three or four follicles to enhance the optical density. (b) Beard hair grafts are thicker with shorter intradermal course as compared to scalp hairs. Note few follicular units have two or three follicles per unit. (c) Pubic hair grafts appear thick and have a short, curved intradermal course compared to scalp hair grafts. Such grafts require a wider punch or manual needle follicular unit extraction (FUE) to reduce graft transection. (note a few follicular units having two follicles per graft). (d) Axillary hair grafts harvested by follicular unit transplant (FUT) method. (FUT is easier for axillary hairs because of the difficult to access location for doing FUE and resultant scar can be hidden in the axillary folds)
