Graft survival rate
The share of transplanted hair follicles that take root in their new home and keep growing. It is the number that decides how full a hair transplant looks, and the one most worth understanding before you book.
How many moved hairs actually grow.
Not every follicle that is moved survives the journey. The survival rate is the proportion that lives and keeps producing hair.
In a hair transplant, follicles are taken from a donor area, usually the back of the head, and placed into thinning or bald areas. Graft survival rate describes the proportion of those moved follicles that take root and continue to grow hair over the following months. It is sometimes called the graft take rate or yield. Because the final look depends on how many transplanted hairs actually live, this number matters more than almost any other when judging a result.
Published figures for well performed transplants are commonly reported in the region of 90 to 95 percent, with some experienced surgeons describing higher yields under careful protocols. These are reported ranges from clinical sources, not a promise for any individual. Survival cannot be confirmed on the day. It is judged over roughly the following year as the transplanted hairs shed, rest, and regrow. A clinic that states a precise guaranteed percentage for your case is overstating what can be known in advance.
Several factors drive the number. The biggest is how gently the follicles are handled, since crushing or cutting them during extraction, known as transection, damages yield. Time out of the body matters too, as survival tends to fall the longer grafts wait before placement. Patient factors such as smoking, which reduces blood supply to the scalp, and general health also play a part. None of these are visible in a glossy before and after photo, which is why the process behind the number is what to ask about.
A number you cannot check for a year.
Hair transplants are one of the most common reasons people travel for treatment, often to high volume markets where price is the headline. The catch is that survival rate is only proven months later, long after you have flown home. By the time a poor yield is visible, the clinic is in another country and a correction means more grafts, more cost, and a limited donor area that does not regenerate. The donor supply is finite, so a wasteful first procedure has a lasting price.
So treat any quoted survival figure as a claim to test, not a guarantee to trust. Ask who physically performs the extraction and placement, and how many cases that named clinician handles in a day, since very high daily graft counts can mean grafts wait too long or are handled by less experienced staff. Ask how the clinic measures and reviews its own results over the following year, and what happens if growth falls short. The honest answer is that no one can promise a number. A clinic that explains its process and its limits is more reassuring than one that promises perfection.

Want a clinic that explains its yield honestly?
Send one brief and we route it to vetted clinics that name the surgeon, explain their handling, and talk about results plainly rather than promising a number. You choose, with no pressure.
How we make money: the guides are free and no clinic can pay to be named, ranked or recommended. We never name clinics. Get Matched is an optional service that helps keep the guides free and independent of any one clinic; using it is always your choice and you are never charged. How this works.
