How Many Hairs are In a Follicular Unit Graft?
Wednesday, October 31st, 2007This is a great question and one not often asked enough!
In a hair transplant, follicular unit grafts are hair groups that occur naturally in the scalp. Each follicular unit grafts contains hair in groups of 1s, 2s, 3s, and 4s. The average number of hairs in a follicular unit graft is different for every hair transplant patient however, overall it is said to be around 2.2 hairs per follicular unit graft.
Personally I think it is beneficial when a hair restoration physician provides detailed hair counts with hair count breakdowns so that the hair transplant patient truly understands what they are receiving.
As an example, a hair transplant patient that received 4000 follicular unit grafts but only 7000 hairs may have a similar result as a hair transplant patient that received 3000 follicular unit grafts with 6900 hairs. Though hair transplant patient one has a far greater number of follicular unit grafts, the hair count is pretty similar.
Of course, the number of transplanted hairs is not the only thing that establishes an illusion of density. There are a number of other variables such as hair characteristics, proper placement of the hair grafts, hair coverage verses hair density, and of course the selection of a quality hair transplant physician.
Keep in mind also that not every hair transplant patient will need the same number of follicular unit grafts to achieve their hair restoration goals.

This is a common problem for young men, who want to have all of their hair restored. I think your hair transplant doctor was very wise in telling you what he did. You have no idea (nor does anyone else, including the hair transplant doctor) how bald you may become some day. And if you start filling in the crown/vertex as part of the initial plan on a man in his 20’s, and male pattern baldness (MPB) progresses and logarithmically enlarges, as it almost always does, and the project in that area can’t be completed, you will have a huge bald halo around a patch of transplanted hair and will look very abnormal, and there won’t be any donor hair left to fill in the halo.
