I had seen the twistband hair ties in my friends Birchboxes before, but I had never received one. This month I was pleasantly surprised to see I got a twistband headband in my box.
I immediately took it out for a test run to a yoga class and the thing didn't move an inch. Through all the down dogs, vinyasas, rag dolls, and all upside down poses it didn't slip off once.
I have a LOT of hair and am always fighting with and rearranging my headbands, especially during yoga, so this was a total win.
