Medication and graft survival: what evidence exists

What actually determines whether a graft survives?

Graft survival is determined by operative variables: time outside the body, dehydration, mechanical trauma (with bulge-region damage more harmful than bulb damage), storage conditions, and recipient site quality and density. All of these are settled before you leave the clinic; nothing taken afterwards revisits them.

Does any medication improve graft survival after a transplant?

There is no good evidence that Finasteride or Minoxidil increases the proportion of transplanted grafts that survive, nor that supplements, topical gels or dietary changes do. PRP's transplant-specific evidence is weaker than its evidence in medical hair loss, and hyperbaric oxygen's evidence base remains small, though that does not make these treatments useless.

• No good evidence that Finasteride or Minoxidil increases the proportion of transplanted grafts that survive
• No good evidence that supplements, topical gels or dietary changes do
• PRP's transplant-specific evidence is weaker than its evidence in medical hair loss
• Hyperbaric oxygen has been studied but the evidence base is small

That is not the same as saying these treatments are useless. It is saying they are not doing what people often assume.

What is medication actually for if not graft survival?

Medication is for protecting the native hair around the grafts, which keeps thinning regardless of how well the surgery went; that is a real and important job, which is why medication is standard alongside surgery. Confusing that job with graft survival leads to disappointment, since Finasteride was never meant to improve how many grafts take.

What should you focus on instead if graft survival is the priority?

If graft survival is what you care about, the useful questions are about the surgery itself: expected out-of-body time, team size, transection rate, holding solution and session size. A related article on out-of-body time and graft survival sets out what the evidence on this actually supports.
