Bunheads Hair Pins
At ballet class it's a requirement for your hair to be nicely pulled back and away from your face. I use these hairpins to put in my bun every single day and they're awesome. My hair is super thin and can be difficult to pull back as it will just slip out of my fingers or fall out of a hair elastic. These pins plus a hair net keep my hair in place whether it's for a class, a rehearsal or a show.
I know many girls with thick hair who also use these pins and love them as well. They'll work with any different type of hair.
