Extracting cells from dermal papila cut from the scalp. Expansion of those cells, these guys they use 1000's of little 3d scaffolds help to keep those cell from differentiation into cells of different niches when they expand them - it basically keeps the new cells acting as though they were in the donor area whilst keeping them in what are essentially clusters of cells similar to the pre-cursors of the hair follicles you get in the early stages of development once expanded.
Anyway, once these cells are sufficient they'll insert these baby papilae back into the scalp.
You're obviously a very resourceful person and can easily find more detail on this if you're not going to be as knee jerk as to dismiss them as credible players in the long term.
Roland Lauster is one of their scientific advisors, there's a lot of good peer reviewed articles by him if you want to read up on the intricacies of their processes. A post on a forum is hardly a suitable platform for that volume of detail, and I'm not here to spoon feed you with information that is freely available online.
