TIY is the first customizable hair tie on the market. Created to fix the never ending issues of your current pony tails, the comfortable TIY Fabric and the Loops Method, make it the premium hair tie. Over 2 years of testing to get the material right, the durable elastic is designed to keep hair confidently secure without slipping, retaining shape and stretch for months after use compared to similar products. It doesn’t dent or crease hair like regular hair ties often do, and it also helps prevent hair-related headaches.
