When can I dance after FUE procedure?

If you already drank beer and danced, it would be a moot point to ask when you can dance.  There is nothing wrong with dancing.

2 weeks post FUE you really have no restrictions.  The only time to be concerned is if you still have crusting where the grafts where placed as crusting and sweat can lead to bacteria.  However, at 2 weeks, just about every patient is able to do full workouts, play sports, etc.  Hope you enjoyed your night out! 

Almost certainly not. At two weeks most doctors would clear you for strenuous exercises, so a little light dancing the day before should be totally fine. Really after 13 days the only way to damage your grafts is through significant trauma because they've established themselves really solidly by then.

There are restrictions after FUE in the first 7-10 days, but nothing after that.

You are free to enjoy your life now!

At 13 days you can pretty much dance all night and it shouldn't have any negative affect on your transplanted grafts. 10 days is usually the magic day where everything seems to settle and you can resume your regular activities. 

At two weeks you can do anything you want, full exercise, run  a marathon or do a full workout at the gym
