What does it mean?

^ right, that was my point. Follicle stem cells NEVER disappear. Underneath the skin, we are all perfect NW0's with perfect patterns.

If these new treatment are only rejuvenating/activating existing follicles/stem cells, then great - keep making injections until your hair is as thick as you want.

The problem is if they'll ignore existing stem cells/follicles and try growing BRAND NEW FOLLICLES. This would look awful as hair will start appearing in random places among the rest of your thinning hair..... also, what about women? What's the point of cloning shitty follicles?

imo, i doubt histogen is creating brand new follicles, they are witnessing revival of dormant follciles.
