I would give these a negative star if I could! They work absolutely fine for about 4 hours. At about 5 hours they literally start disintegrating! It doesn't matter if it's a small section of hair or a large section of hair. Literally every time I used these I would know they would last for about 4 hours and then my hairstyle would fall apart. Absolute garbage!
I use these all the time in my own hair and in my girls hair for competitions. We have naturally curly/frizzy hair and luckily these don't get all tangled up in our hair! I love that they slide out easily instead of me having to cut them out.
