Only a couple of days if I'm going to work because it gets too big, about three days otherwise. I pineapple to maintain the style. I just add a little water and a little Buttercreme and retwist it overnight to create a twist out for the remainder of the week. My hair doesn't hold B/Os as long as twist outs though, so it may last longer for you. Another tip is that I like to roll the rods over rather than under for more volume.
