Great if you figure out the right method.
I have been on the hunt for a no heat way to curl my hair.  I’ve had a perm, but I don’t like the damage it does, making my hair feel like straw.  I bought the smaller flex rods, but those make me look like Shirley Temple. These 1” diameter rods give me the look I want.  I’ve only slept on them once. That was super uncomfortable. So I use a keratin smoothing product and get my hair only slightly damp. I use two packs (8 rollers). I really like the result.
