I am three weeks post FUE surgery with 1700 grafts. When would it be safe to return training jiu jitsu?

After 3 weeks from an FUE hair transplant procedure, you should have nothing to worry about as far as returning to your regular physical activities, including Jiu Jitsu. The donor sites are all healed, and the recipient areas are also safely healed. Just make sure you wash your hair very well after training, in order to clean it well.

In general most doctors would suggest 3 weeks after a hair transplant surgery (FUE or FUT) before resuming heavy exercise or contact sports (which include combat sports and grappling).  Most importantly, ASK YOUR OWN DOCTOR as they have have specific issues with your specific surgery and circumstance.  

There's usually no issues with intense exercise at 3 weeks provided everything has healed nicely. It's always a good idea to run the question by your surgeon in case there are specific details about your surgery and post op course that might actually benefit from a bit longer rest. But 3 weeks is generally okay. 

It is really best to ask your own hair transplant these sorts of specific questions relating to post op care as every surgeon will have his/her own preferences.My own advice to FUE patients is that they can go back to contact sports once their scalp has completely healed and all crusts have fallen off both in the donor and recipient area. It's a different thing for strip surgery where I advise 6 weeks although the donor wound will take up to 3 months to gain its maximum strength.

3 weeks after the surgery its definitely safe to return to your normal physical routine. Though you have to still be very careful not to hit or bruise your head. If you have some head protection gear, you can continue with your excercises normally.

At our clinic we recommend to take it easy girl the first two weeks.  You can do light work out after the second week, heavy lifting after three weeks and contact sports and swimming after four weeks.

Full exercise is ok at this point in time provided that all of the crusts have disappeared. Hitting your head is always a concern, but I would suspect that at 3 weeks, you should be able to engage in this sport unless you have any symptoms left from your transplant.
