More time is required for FUE due to the order in which the procedure is carried out. Since the extraction process is slower than strip harvesting, large procedures may need to be performed over two days.
The maximum follicular unit graft yield is lower than with FUT. The inability to harvest all the hair from the mid-permanent area donor area results in decreased numbers of grafts.
With each subsequent session, the scarring in FUE is additive. If the first session is 2,000 grafts, there will be 2,000 tiny round scars making subsequent FUE procedures more difficult.
Is Shaving required?
In larger hair transplant sessions, the entire donor area must be shaved.
FUE takes longer than FUT resulting in slightly higher hair transplant costs.
