I didn't think it possible for hair ties to be this gentle on hair. There is no pulling, no breakage, just a secure hold. With one exception-maybe don't ride extreme coasters. Used a Tiy to hold my hair in a messy high ball for a day at Busch Grdens. Iron Gwazi apparently liked it as well as it came off during the ride. It is an aggressive coaster. Will be ordering more. I love these ties. Wish I knew about them sooner!
