When can I start bending my head after FUE, specifically yoga involving a lot of downward facing dog?

I used to have a daily practice, 1-1.5 hours long, lots of downward facing dog and being with the head down from the waist. I've just hit 2 weeks post FUE and so far haven't done any exercise except for mild walking and some non-strenuous stair climbing. I've kept my head up so far and still sleep with my head elevated. I no longer feel pain in the donor area, discomfort is almost unnoticeable, and the trainsplanted hairs look well and crust-free. How long should I wait?
