On another forum a member asked the question: What does "average" and "above average" donor look like? It was a good question and a point that is probably much more complicated than most would think.
Many may say it is just down to density per cm2 of follicular units, but it goes deeper than that; aspects such as hair calibre, number of hairs per follicular unit average, spacing between each follicular unit as well as miniaturisation if any in the donor are all very important aspects to consider when assessing the donor area for suitability.
As a general around 75 FU cm2 is considered to be about average from a numerical calculation aspect but then add in for example the average number of hairs per natural group and an average donor could become below average.
Above is an example of how a donor could have very similar actual FU density but vary greatly in quality for a hair transplant. The hair count is greatly different from A to C and would require very different approaches and distribution of the hair if a hair transplant were performed.
