Review (1/5): Not for long, thick, and wavy hair
These things are lousy for long and thick hair. Not comfortable and made my hair look odd due to the coiled nature. As for dents, I didn’t notice a difference. Removing it was a pain and pulled out hair. My hair is very long (waist length), thick, and wavy... obviously this isn’t a product for my type of hair.
By the way, I was originally sent a small dog play ball! Took me a bit to find out why I received it (error by the vendor, Beauty Collection). So if you get some weird item... check your orders ;)
