This was my first time actually using one of these heatless, big curling rods! I had them on overnight. I want to say about 10 hours in total - not the most comfortably asleep, but a lot more comfortable than I assumed it would be haha I’m not sure if this will hold all day because my hair is quite heavy but quite impressed with how big and bouncy the curls are! I didn’t put any product in my hair, but it might be smart to add a bit of moose when putting it up in these rods ✨🫶🏼 LTKgrwm LTKBeauty LTKselfcare
