Hair Transplants: What Is the Average Number of Hairs Per Follicular Unit?

The following response to a question from the Hair Restoration Social Community and Discussion Forums, was written by forum member “Gillenator”.

Do you have any idea what the average hair-per-graft ratio is? I had 2,129 grafts for 4,013 total hairs from my last [tag]hair transplant[/tag], which left me with a ration of 1.89. That seems low to me; I had 1,233 doubles, but only 315 triples–that seemed extremely low. Nothing I can do about it, but just wondering where that stacks up. I seem to see a lot of graft counts with roughly half as many triples as doubles rather than one-quarter.

The overall average is 2.15 – 2.3 hairs per graft per individual. But depending on the case such as the rebuilding of a hairline, many more single hair grafts are going to be used which would bring the average per graft downward. Let’s also define the graft as an uninterrupted natural occurring [tag]follicular unit[/tag] in the scalp.

The best way to ascertain the average with [tag]follicular unit strip surgery[/tag] ([tag]FUSS[/tag]) is to have the overall strip evaluated for the total number of FUs along with the total number of hair shafts to determine the overall average from the typical donor region.
