I use hair-ties everyday. As a collegiate athlete and a personal trainer, my hair is always pulled back out of my face and needs to be secured. After a while, regular hair-ties damaged the bottom of my hair from pulling them out of my hair repeatedly. Last year, I was introduced to the Invisibobble hair rings and will never go back to regular hair-ties. The rings don’t damage your hair, like regular hair ties can and did to my hair.
