As someone with really thick hair this looks like something out of the 50's phone booth not a hair tie. They hold a super thick ponytail far better than a traditional elastic you don't have to wrap it around 10 times. Even in fine-hair the tester said that two twists kept her ponytail firmly in place. But that's not all,it secures your hair without leaving behind any marks. After an hour-long workout, my hair emerged from its ponytail as smooth as it went in, and just for the record, this ring's hold was impressively strong. If the coils do loosen over time, hit it with your blow-dryer and it will magically bounce back. These are seriously brilliant for messy buns too. Try you wont be sorry.
