Can I do minor exercises after Hair transplant?

I personally see nothing wrong with that if you're use to doing push ups and you feel well enough to do them.But you really need to check with your doctor because all doctors will have slightly different opinions and post-op instructions.

For the first 2 weeks you can only do light excercisies like walking, sit ups and push ups may not really be appropriate for now. Resume heavy excercises after a month. Avoid practices that may be too risky or might affect your results. 

Every doctor may have a slightly different regimen, but I would recommend following the advice of the doctor who performed your surgery. It doesn't make sense to risk a complication just to get back to the gym a little bit earlier. If you really can't wait, call the doctor who did the procedure and ask him/her whether you can start working out a little sooner. Good luck.

I would check with the doctor but in general with FUE transplants you can return to normal activity after 7 days.

Be sure to check with your surgeon for his or her specific recommendations.  The main issues with regard to exercise is preventing sudden changes in blood pressure that could affect the grafts. For patients who had follicular unit extraction procedures (FUE), I advise return to light cardiovascular activity at day 8 and light weights at day 11. Heavy weights at day 14.For patients who had strip surgery (FUSS), I advise return to light cardiovascular activity at day 12 and light weights at day 15. Heavy weights at day 21. The main issue with FUSS type procedures is proper healing of the donor site.Push ups sit ups and pull ups are best avoided for 11 days -14 days for FUE and 2-3 weeks for FUT (Strip surgery).Please check with your surgeon. 

you can do light exercise such as walking after one week. Contact sports and heavy lifting after three weeks. Swimming after four weeks.  However since every one heals differently the above is just a guideline and in general It is good to use common scene and use a bit pre caution after any procedure. 

Exercises with a strip procedure are restricted to not lifting more than 50 pounds for 3 weeks or so.  For FUE, there are no restrictions. For both of these procedure, I would not recommend scuba diving for 4 weeks or so. I told one of my strip patients the other day that he could run the marathon that weekend (3 days after the surgery). He thought that was great but he told me that he never could run a marathon and asked me if the transplant gave him a new superman strength at the surgery. We both laughed and he did not run a marathon but if he wanted to try, he could.There are no restrictions one week following a hair transplant other than scuba diving.
