The survival rate of transplanted grafts is one of the most important determinants of hair transplant outcome. Understanding what affects survival helps you make better decisions about your procedure and clinic choice.
What Is a Good Graft Survival Rate?
In skilled hands, FUE graft survival rates of 90–98% are achievable. A rate below 85% is considered poor and suggests problems with extraction, handling, or implantation technique. The difference between 90% and 98% survival across 2,000 grafts is 160 grafts — enough to make a visible difference to density.
Factors That Affect Survival
Surgeon Skill and Technique
The extraction technique is critical. Punches that are too large, too deep, or at the wrong angle transect (cut) follicles. Transected follicles will not grow. Only a surgeon with extensive experience and meticulous technique consistently achieves low transection rates.
Graft Handling Time
Once extracted, follicles begin to degrade outside the body. Minimising the time grafts spend outside the scalp — and keeping them cool and hydrated — is essential. Clinics that separate extraction and implantation by long periods risk poor survival rates.
Storage Solution
Storing grafts in chilled saline is the minimum standard. Some clinics use enhanced solutions such as HypoThermosol or ATP-enriched solutions that can improve graft viability during longer procedures.
Patient Health
Smoking significantly impairs blood supply to the scalp and reduces graft survival. Patients should stop smoking for at least 2 weeks before and after the procedure. Poorly controlled diabetes, anaemia, and certain medications can also negatively affect outcomes.
Recipient Site Creation
Dense packing without adequate spacing between recipient sites can compromise blood supply to newly placed grafts. There is a maximum number of grafts that can safely be implanted in a given area in a single session.
How Do You Know If Your Survival Rate Was Good?
Assessment at 12 months tells the full story. If expected density has not been achieved, or if areas of the transplant are patchy without an obvious cause, poor graft survival is a likely explanation.
