I have about 90cm2 of baldness and about 200cm2 possible donor area. When I counted 1cm2 of donor 3 times I got 110,113 hairs and 123 Fu per 1cm2. I was wondering if the ones with red arrow are still the same Fu even though the hairs are spaced out? Different to one with green arrow.
You are pointing out the follicular units that have more than one hair. Sometimes they exit the same pore and sometime, it appears to exit next to the main pore? The count of 110,113 hairs is about the average hair count in a Caucasian male and the number of follicular units are about 50,000 or 2.2 hairs per follicular unit on average. Clearly some of the Follicular units have higher hair counts and other may just have a single hair. If you look at the leading edge of a normal hairline, you will see all one hair follicular units transitioning into more hairs per follicular unit as you go back from the leading edge. You were very astute in your analysis. The next step is to calculate the size of the balding area you are thinking about transplanting. That is just the beginning of the next analysis where multivariate analysis comes into play. The other variables that must be considered is (a) hair thickness, (b) character of your hair (wavy or straight), (c) the thickness of the hair shafts (fine, medium or coarse) and last and most important is where you are heading with your existing balding (based upon HAIRCHECK analysis, family history, your age and if you are going to treat the progressive nature of balding and what is your long term medical plan with regard to going forward management).
