Is there a difference between a follicular unit and a graft
Is there a difference between a follicular unit and a graft?
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.
