I have tough thick hair and nothing "without heat" works for me. I really do like the concept of putting something comfortable on and forgetting about it and still getting results ( because I am lazy), so I gave them a try. I left them on only for an hour and still the curls were beautiful. Easy to put on, comes in different sizes. Does not bother while sleeping and give you the curls you want!
I love them but my hair is too long. Came with two free hair nets. I'll try to update my review once I've used them.
I have super thick long hair and I'm so glad these worked! Since my hair is really long and can't roll up hair to my scalp I decided to put it in a ponytail and then start rolling in the spoolies. They do tug a little, but overall great for overnight curls!
These curlers are awesome! They are pretty comfortable to wear, even sleep on, and fairly easy to use. I love the waves/curls my hair gets when I use these!
