A waterfall braid is a french braid where you only add hair from one side. I never know how to end a waterfall braid delicately and usually just end up collecting the remaining hair in a ponytail or a bun. For this hairdo I did three braids that end in a side ponytail.
This reverse french braid adds a little fun to a regular bun. It's a bit difficult to do on yourself but it helps if you stand up side down so the hair doesn't get in the way of braiding...
