How long after FUE transplant can I shave my head with a razor?

for the recipient area normally you should wait around 5-6 months before shaving. it is better to use scissors in meanwhile. But it is better if you consult with your doctor.

It is best to ask your surgeon about post operative care as each doctor has their unique regimen.   You can shave your head when your wounds have healed.

It is my philosophy and opinion not to be aggressive  with the transplanted hairs until they have healed and fallen out. So in my practice, we don't use any razors until all the hairs have fallen out between 3-4 weeks after the procedure. There may be a chance that when you use a razor you may actually damage the grafts. Although there are no studies that have concluded this, but in my practice I take a very conservative philosophy and it has helped me out tremendously with my results.
