I did a comprehensive analysis of gc83uk’s donor recently. If you Google “Analysis of gc83uk’s Donor - 2nd & 3rd HST Procedures” you’ll be able to find it.
The most interesting thing I discovered, and as far as I know nobody else has brought this up before, was that 30% of the extracted follicular units, regenerated with less hairs or were thinner.
To give people an idea of what this means, I’ll give a conservative example. Let’s say a person has an average of 2.0 hairs per follicular unit and undergoes an HST procedure. We know that 20% of the extracted follicular units will not regenerate. On top of that, let’s say 30% of the follicular units regenerate with half as many hairs. This means that the true regeneration rate for hairs in the donor is 65%.
Let’s extend this to the recipient side. Let’s say 10% of the transplanted follicular units do not yield and 30% appear thinner, or have half as many hairs. The total yield for hairs on the recipient side is then 75%. The true multiplication rate, in this case, is 1.4x.
This is why I’m very interested in including the recipient area in any future analysis. We have a good idea of what’s happening in the donor but the recipient is missing. Without both, you can not have a complete analysis. As a result, I started a thread that you can Google, “The 50 Graft Test Procedure,” that would answer the key questions so I hope people support it and start being a little more proactive.
