The video (which can be seen above) was captioned: “Did you know the higher the angle you hold your straighteners the bouncier the curls? For beachy waves, you want to glide the styler down the hair as close to your body as possible but for bouncy curls go for a 90-degree angle.”

As demonstrated in the short video, the first hair piece that Cusick styles is curled holding the straighteners at 0°, which works to create a loose, casual-looking wave that would be perfect for a beachy, relaxed feel. The second extension is curled holding the straighteners at a 45° angle, resulting in a tighter curl that’s ideal for creating a more defined look or for people whose hair doesn’t hold a style quite so well.

Finally, the third curl is done at a higher 90° angle, which, as you can see, styles hair into a tight, bouncy-looking curl that will turn into a salon-inspired blow-dry-esque finish when it’s done on a whole head of hair.

Clever, right?

Holding straighteners at different angles can create various curl types – here’s the proof
