I voted, "All or almost all the time." I would say my hair is in a PS (cornrowed beneath LFs/wigs) 100% of the time in a given month, and is only taken down to wash/condition/massage my scalp (my wig is off when I'm at home, and only worn when leaving the house or having company over, lol--so my scalp can "breathe" and edges get a break).
I'm mostly a home-body, so I find that just keeping my hair braided and moisturized beneath wigs is the most convenient style I can do right now. It's low maintenance and I can just throw the wig off to easily get to my hair, vs. a sew-in weave.
I have very low energy due to anemia, and simply don't want to bother with my hair most of the time--but I want to grow it out quickly, hence the constant PS'ing. In hot summer I store the wigs away and get braids with extensions or wear my own hair in buns.
