Question:
Is there a difference between a follicular unit and a graft?

Answer:
A graft is considered a piece of tissue that can be obtained either from dissecting a strip from the donor area or using individual techniques called FUE or Follicular Unit Excision.

Each individual piece is considered a graft which can have either 1, 2 or 3 follicles in this graft. So a follicular unit technically is a graft.

All follicular units are grafts but the reverse is not necessarily true. All grafts are not necessarily follicular units.

A follicular unit is specifically a natural occurring, tightly grouped follicles that either occur individually or in 2, 3, or 4 hairs.

A graft can be any piece of tissue that contains hair follicles; it could be 10 or 20.

All follicular units are grafts but all grafts are not necessarily follicular units.
