Fatal, when thinking about this I always recall BioAmide’s experiments back around 2000, where they implanted donor-area cells into the non-hirsute skin behind the ears of test subjects (i.e., the post-auricular space). This is an area that never grows terminal hairs, so there is never any hair cycling there like on the hirsute parts of the scalp.
The BioAmide experiments were successful, and new terminal hairs grew. And obviously, they weren’t stimulating dormant, miniaturized follicles that were affected by MPB.
Experiments like this, along with others conducted by Jahoda and Reynolds, etc., seem to indicate that there is follicular neogenesis going on. The principal researchers don’t seem to disagree. Most of them have said that there seems to be some follicular neogenesis happening.
I see the two phenomena – follicular neogenesis and stimulation of miniaturized MPB follicles – as simply two manifestations of the same cellular mechanism. They’re not mutually exclusive. I think both are happening together. Time will tell, but even Dr. Kemp seems to agree with this hypothesis, from some of his statements.
Also, Dr. Washenik and Aderans specifically call their procedure “follicular neogenesis”. It seems they are confident that new follicles are being created.
By the way, I am not drawing any distinction between the ICX procedure and the Aderans procedure. I don’t think they’re fundamentally different. Aderans has talked about using bioabsorbable, chemical “scaffolds” to hold the cells in place (actually these are microscopic polymers which presumably are injected right along with the cells). But in most descriptions of Aderans’ procedure (where they’ve called it “follicular neogenesis” – as in the Wired magazine article a while back), there is little or no mention of the scaffolds.
In any event, the use of scaffolds indicates that the injected cells have a tendency to aggregate together to form brand new follicles. I don’t think the scaffolds are necessary to induce this phenomenon – they just ensure that it happens easier and more reliably, so that the “yield” per injection is higher.
Working backwards by induction from their use of scaffolds, we can induce that injected donor cells do have a tendency to coalesce and form brand new follicles, under the right conditions.
Thus, a valid inference from the above is that so-called rejuvenation (i.e., regeneration) of existing, miniaturized follicles, is not the exclusive means by which HM works.
