Review title is Not good for thick hair [SEP] I would definitely recommend these hair clips to anyone whose ponytail is less than an inch in diameter. My hair is thicker due to the texture, so even when my hair is straightened, I had an issue getting the clip around my ponytail and trying to squeeze it closed (since it works by pinching the hair).  It also makes the start of the pony tail really extended and bulky so if that's not the look you're going for, avoid this .
