Review on 40PCS Heatless Wave and Spiral Hair Curlers: No Heat Damage, Two Styles (16inches) - Ideal for Women and Kids’ Short/Medium Hair by Kaitlyn Nelson

My son's girlfriend was a tester of these curlers. She said the wavy pieces were a little tricky to use. She had to wrap her hair around the hook a few times to keep it in place while she pulled it through. The straight parts were much easier to use. She remarked that it would be easier for everyone to use if there was a second person doing the curling. When she first used it, she didn't use the hair dryer and the curlers didn't work properly because her hair wasn't dry enough. Another application, making sure her hair was dry, produced better curls. Very comfortable to wear and you get a lot of curlers. Her hair is medium length.
