Hair Transplant Surgery: How Many Hairs are in a Follicular Unit Graft?

I’m considering having a hair transplant and recently began investigating the procedure. I understand that modern techniques involve transplanting follicular units unlike the large “plugs” done in the old days and that clinics typically charge on a per graft basis. What I want to know is how many hairs you get from a given number of grafts?

A follicular unit graft can have anywhere from 1 to 4 hairs but you can average the number of hairs per graft to be about 2.2. Using that figure, 1,000 grafts would yield about 2200 hair follicles. The number of grafts required to successfully restore a patient’s hair will depend upon several factors such as; the degree of hair loss, the caliber and density of the donor hair and the individual’s personal hair restoration goals.

Clinics charge per graft regardless of the number of hairs in the grafts. Bear in mind that they will place the grafts strategically based on the number of hairs in the graft. For example, single hair grafts will be used mainly in the hairline while twos and threes will be used in zones behind the hairline to enhance the illusion of density.
