So here are the official figures from Histogen, published in the peer-reviewed journal.
At 3 months:
Shaft thickness +6%
Thickness density +13%
Terminal hair count +21%
No mention of total hair count, presumably it was not statistically significant
At 5 months:
No statistically significant increase over 3 months (obviously some individuals had better results at 5 months but the overall change was not statistically significant).
At 12 months:
Total hair count +16%
Thickness density +18%
Terminal hair count +30%
So there you have it, straight from the source. A single injection of HSC resulted in an average 30% increase in terminal hair count at 12 months. There is some other interesting stuff in the paper too but I haven't read it all yet.
If TOTAL hair count increased, that means that the treatment must have induced a few entirely new follicles to form as well. That's the understanding I always had - I believe what I read in one of their articles or press releases that HSC was effective in transforming vellus hairs back to terminal hairs, and it also appeared to create brand new terminal follicles as well.
Histogen has absolutely blown everyone else out of the water so far. I see this as being the possible cure, especially if they really are creating new follicles in addition to reversing miniaturization. I am cautiously optimistic about this being the cure for people with bald scalps and very optimistic about this being the solution with people who just have thinning. Go Histogen!
