Review (4/5): First time using hair rollers and worked fine!
I have shoulder length hair and it gave me nice curls. I tried both on damp and dry hair and I found it less frizzy when using dry hair. When rolling my hair I found that you have to start from the ends and roll your way up or you'll end up with a tangled mess when unrolling. My rolls did loosen a bit when sleeping but a shower cap might fix that problem. If you have a sensitive scalp it will be painful to sleep in if you don't find the right position.
