Review title is Not as easy at it looks and a little uncomfortable for sleep [SEP] I suggest allowing time while your awake to let your hair dry with these on instead of trying to sleep with them in, not as comfortable.  Not using these and just braiding your hair before bed with it damp can give a similar effect and it’s not so uncomfortable. It does take some learning to get this right and this is healthier for your hair then a hot curling iron. Not sure how often I will take the time to do this.
