Is this only valid for people with hair? Or can I go from, in my case my nw3 to nw2... or an nw5 to nw3?
THEORETICALLY, it should work for everyone. Keep this in mind:
DSC cells and DP cells convert back and forth between eachother (according to Dr. Claire Higgins, read about that
here). A healthy, normal sized follicle that grows thick terminal hair has about 1,200 to 3,000 DP cells (according to Dr. Beren Atac, read about that
here).
Considering that Replicel's method injects DSC cells that surround the DP, we can only hope that all the cells actually latch onto the follicles and are fed/converted into DP cells which enlarges the follicles. Replicel ALSO believes this can create NEW follicles (vellus or terminal hair growing that I dont know). Now, we all know that the results at the 6 month stage we're disappointing, but dosing is still being explored but more importantly, as I always said much like the Samumed results; 6 months is NOT enough time. Finasteride takes up to 12 months and sometimes more to get full results. Even hair transplants where follicles are already in full size take up 1 year and longer to see full results. It's too early to make the assumption that the 6 month period is the end result. Consider this; the cells need to migrate to the existing follicles and regrow the follicles. Any treatment many of us start almost ALWAYS creates a shed which cause a long resting period which can last up to around 4-5 months. Histogen's treatment, when speaking with Dr. Naughton, apparently is dependant on the hair growth cycle. Could Replicel also require this? We'll see. Then of course we dont know how long it takes for NEW hair follicles to form.
As I said, I'm FAR more interesting in seeing 12 month data results from Replicel as well as from Samumed. But we have neither unfortnately, and even Replicel itself doesnt have long term results.
