Heatless waves- with different length options! No way could I sleep in these, but they do work so well! I rough dried my roots first, but I did end up respraying my ends to help the slide through and take the shape better this process from start to finish was roughly 4 hours (maybe could’ve been less but I was afraid they wouldn’t be dry) LTKBeauty LTKgrwm LTKstorytime
