Hair transplant glossary

Ten words you will see on every clinic page, in plain language.

Graft
One follicular unit moved in a transplant: usually one to four hairs that grow together. A graft count is not a hair count.
Follicular unit
Hair grows in tiny natural groups, not one by one. Such a group is a follicular unit.
Donor area
The back of the head. Hair there is usually less affected by hair loss, which is why grafts are taken from it.
Donor density
How much hair the donor area has to give. It limits how many grafts can be moved.
Norwood stage
A standard scale for patterns of hair loss in men, from stage 1 to stage 7.
Hairline
The front edge of hair growth. Its shape and height are planned with the surgeon.
FUE
Follicular Unit Extraction: grafts are taken one by one from the donor area and placed into tiny openings in the area being treated.
DHI
Direct Hair Implantation: a variation of FUE where grafts are placed with a pen-like implanter, so making the opening and placing the graft happen in one step.
Sapphire FUE
FUE where the tiny openings are made with a sapphire-tipped blade instead of a steel one.
Shedding phase
Transplanted hairs often fall out between weeks 2 and 8 after the procedure. This is normal; new growth usually starts later.
