This is my new lazy-hair jam - the braid bun. It's really fast and has worked fairly consistently. This pinterest tutorial gives you the general concept. I basically do a high pony, braid it (upside-down), tiny-elastic the braid end, twist the braid around the base of the ponytail and then Spin Pin the heck out of it with 3 short spin pins and one or two bobby pins to get any loose strands.
I am not advanced enough to fishtail braid the way this tutorial does so if you can, go for it. They show you puffing out your fishtail braid here for bun volume but I do not do this with the regular braid.
Lay your lazy hair tutorials on me if you have them.
