What is a Graft? Understanding Hair Transplant Terminology
Grafts, follicles, strands... The terminology can be confusing. We explain exactly what a graft is and why 3000 grafts does not equal 3000 hairs.
Follicles vs. Grafts vs. Hairs
When you start consulting with clinics, you will hear numbers thrown around constantly: "You need 3000 grafts," or "We implanted 4000 follicles." To make an informed decision and spot deceptive marketing, you need to understand exactly what these terms mean.
What is a Follicular Unit (Graft)?
Hair does not grow in individual, isolated strands all over your head. It grows in tiny groupings. A Follicular Unit (or Graft) is a naturally occurring group of hairs that share the same blood supply and exit the scalp through the same pore. A single graft can contain anywhere from 1 to 4 (and sometimes 5) individual hairs.
- Singles: Grafts with 1 hair. Used exclusively for the very front of the hairline to create a soft, natural transition.
- Doubles and Triples: Grafts with 2 or 3 hairs. Used behind the hairline and on the mid-scalp to build volume and density.
- Multiples: Grafts with 4+ hairs. Used on the crown and back to provide maximum coverage.
The Math of a Transplant
Because an average graft contains about 2 to 2.5 hairs, a transplant of 3,000 grafts actually means you are getting approximately 6,000 to 7,500 individual hairs moved to the balding area. If a clinic promises "10,000 hairs," they are using marketing spin to make the procedure sound bigger; they actually mean around 4,000 grafts.
