@DesperateOne: growth factors would help tremendously but timing is key in my opinion (god I love using "in my opinion" so people don't hang me later when it occurs that i am completely talking out of my arse), they can go to waste and not cause neo genesis if you miss the opportune window.
Follica has found a genius way to keep those tiny wound open and introduce all the magic element right on time, so it seems.
I posted the 1956 study in post 504 (which cotsarelis referenced in one his recent studies), which they found that
dermabrading alone (without any else) resulted in vellus hair generation from areas that have no hair at all. So people cannot claim that minoxidil alone is causing the vellus hair to pop on completely bold areas. They also found that the epidermis was a treasure chest of stem cells that can turn into virtually anything, for example a salamander with amputated limbs will completely regenerate from the epidermis
alone. Everything is in there, the key for terminal hair is wnt expression over a certain period of time before the wound closes.

Most children are capable of such regeneration on they finger tips, they actually compared some of the reactions between this phenomenon in children and salamanders and found that they were similar:

I saw a few years back (on the science channel) a lady in her 30s who got 3rd degree burn to her whole body, she was in a comma and her body was completely wrapped in a solution to prevent hypothermia and infection, weeks later she completely regenerated her whole skin including hair, the doctors thought it was a complete miracle, and they stated at the end of the show that basically in her 30s she got the skin of a newborn, like a new lease on youth. I will try to locate the info and post it.
