Is it okay to use a double-edge safety razor after hair transplant?

There should be no issue with shaving your head 11 weeks after surgery.  If you are concerned contact your doctor.

Peter1111,To shave 11 weeks after a hair transplant whether it is beard or scalp should be totally without consequence. There is less risk of a knick with the electric shaver but the traditional two edge razor is a very close and gratifying experience.Sincerely,Bernardino A. Arocha, MD

Shaving the transplanted area after 11 weeks of the procedure is absolutely ok and you can use electric clipper or blade razor without any consequence but one should do it carefully so as there should not be any Knicks and cuts over the area.

Shaving your hair 11 weeks after transplant should not cause any problems.  By that time you can do anything you normally would do with your own natural hair.

yes, A double-edge safety razor is OK okay to use at the transplanted area after 11 weeks.it does not cause any harm .

At this point in time you can shave with a razor or an electric clipper, either way you should be safe

Hello again, Peter--  I'm not sure if you saw my response to your previous question (link provided below), but that is exactly the type of razor I was talking about. I'm not familiar with this particular brand and model, but give it a try. If you'd like to contact me directly, I'd be happy to provide you with some more detailed guidance including blades, creams, soaps, and brushes.Happy shaving!  --Dr. Ballon
