I love these "phone cords". I stock up on them whenever they're on sale. These don't stretch out and lose elasticity with repeated use, and the grip they give is fantastic. I have straight hair that's TOO silky that nothing could hold enough grip and at the same time doesn't force me to pull out a wadful of hair out along with the rubberband until these came along. So glad they come in black and various colors too!
This is my first purchase of telephone coil hair accessory as i've been doubtful of the ability of the coils to retain it's tightness over long period of stretching. First impression, it is pretty small but the strong grip is comparable to normal rubber hair ties. I'm totally impressed that despite the strong grip, it doesn't tugged on the finer hair near the hairlines (usually I will need to spend extra effort to loosen those areas to prevent my scalp from hurting). I'm not sure how it will fare in the long run or if soaking the loosen coil into a bowl of boiling hot water will "tighten" those coil back. However, I'm definitely impressed.
I cannot believe Iv been sleeping on these. iv tried poor quality ones in the past which was why I was hesitant to get these but so many pro stylists recommended this brand. I love these! They hold my pony fine and I can't even feel the weight like normal hair ties. if your hair is thick and heavy it will slide down over time. Don't pull it out uncoil it one at a time which is what you're supposed to do with any hair tie to avoid breaking your hair. And it quickly goes back to it's normal shape after blowing it with a hair dryer
