Background: Since it is not known precisely how long it will take for grafts to be securely anchored after hair transplantation, the advice that the medical profession has offered patients regarding postoperative care has been somewhat arbitrary.
Objective: This study attempted to provide scientific data that can be useful in refining postoperative hair transplantation protocols.
Methods: Forty-two patients participated in the study. During their postoperative period, each had several grafts pulled to determine at what point they could no longer be manually dislodged.
Results: For the first 2 days, pulling on a hair always resulted in a lost graft. By the sixth day, pulling on a hair no longer dislodged the graft. Pulling on an adherent scab always resulted in a lost graft through day 5. At 9 days postoperatively, grafts were no longer at risk of being dislodged.
Conclusion: The presence of crusting extends the interval that grafts are at risk of being dislodged postoperatively. If one can prevent crust formation following hair transplantation, this would both shorten the time patients are at risk of losing their grafts and enable them to return to their normal hair care routines more quickly.
