Review title is Not for long, thick, and wavy hair [SEP] 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.<br /><br />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 ;)
