Weeks after the hair transplant, when the so called shedding takes place, the implanted hairs enter the telogen phase at the same time and are synchronised in their cycle, so to speak. Before the hair transplant, they had their own individual cycle, so they were in different phases at the same time. After approx. 3 months, new growth begins and the anagen phase has started, which can last between 2 and 6 years. How do the grafts know what their original cycle was? Because otherwise it would be the case that since all the implanted hairs entered the anagen phase at the same time, they would all enter the catagen and telogen phases at the same time, since they were synchronised?

so it is also true, that the implanted grafts go throught multiple cycles in this 12 months?

Thanks a lot, that makes it much clearer for me

What I don't understand is that the time between the extraction and implantation is very crucial and should be less than 4 hours for 90% growth and at the same time follicles implanted will still need 5 days to connect with the blood supply to receive Oxygen. Or is the "5 days to connect" timeframe incorrect?

Just quick to confirm: after the first days and in the following weeks post surgery, the inserted grafts (if they are connected to the blood system and are not weakened to much by the procedure) are growing right? I am wondering about the well-known phenomenon that the grafts first create thick terminal hair as if nothing had happened and then only after a few weeks, the shedding takes place and the grafts realize that they were outside the body for some hours.

It is a common understanding, that you have to wait 12 months or up to 18 months to see the final results. On the other hand, what is the timeframe to wait to see, if the procedure had failed (Grafts were the weak to create strong terminal hairs)? I have seen these tables, where is stated that after for example 6 months there are only 50% of the implanted grafts have grown out.

so the long-out-of-body time is not unintentionally; I've read about this case, that the surgeon had to stop the bleeding like 2 hours and there after it was possible to insert. Before stopping the bleeding, the grafts were pushed out again.

push

Thank you for your answers. I have read that under certain circumstances it can happen, that the patient bleeds heavily during the operation. This would lead to the situation, that the inserted grafts being pushed out again after insertion (sorry for the unscientific description). In this case, the blood flow in the operation area would first have to be reduced by administering medication. This makes it necessary to store the harvested grafts for a few hours and not to insert them directly as planned.

please focus on his first part of question. I think he means, that if the implanted grafts grow the first hair direct after surgery, they are meant to be strong enough to survive and will grow strong terminal hairs after the shedding and re-growth in 3-4 months. This is my questions as well as you don't find any information about this survival rate in this forum or internet

Hi I want to refer to this study here: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3764754/#:~:text=Thereafter%2C the time taken for,from 1 to 2 h. Apparently there are no more recent studies about this or I just can't find it. So, if you have more recent studies about this, please post here. Graft survival out of the body Maybe this is a questions for doctors only? Assuming a surgery, where grafts are outside the body for 8-10 hours. As a consequence, the grafts would be irreversibly weakened, survival rate would be reduced. How would this manifest itself in the patient exactly? Would no more hair grow from the inserted graft or would only weak, thin hair grow or would normal hair grow and then fall out again after a certain time? As is certainly well known, most patients experience so-called shedding after approx. 2 weeks, where implanted hairs start to grow very slightly direct after the surgery and then fall out again and start growing after approx. 3 months again. Assuming that the grafts are weakened by the excessively long out-of-body-time while surgery, would the grafts then no longer be able to produce any hair at all in this first time window (before the shedding begins)?
