I have done my FUT surgery 2 weeks ago. I start playing cricket on 11th day. Is it ok or I should stop playing cricket?

If you had a hair transplant surgery and have post operative questions, it is best to contact your doctor.  If you want to play cricket, make sure your wound has healed adequately. 

It depends on how good a cricket player you are. Just kidding.By two weeks your transplants are stable. Just make sure not to take a direct hit to the head, which I'm sure you do; and remember to shower afterward to get the grease and sweat off.

I would advise that you follow the advice you were given by your surgeon.The main concern at day 11 is widening and poor healing of the donor scar. Every surgeon has slightly different advice. I advise my patients to wait until day 15.

Go for it. Cricked or other sports are all in the game after a good FUE is fully healed by the 11th day easily.
