Theflat ironis a staple in just about every home.

It turns out that straighteners are great for a whole bunch of other hairstyles as well, perCosmopolitan.

We’re talking waves, tight curls, and even crimps.

These classic straightener curls look super similar to a coil that you’d get with a curling iron.

Then, begin to spin the barrel of the straightener while keeping the hair taught.

It’s that easy!

Plus, from experience, these curls stay intact so much longer.

Getting old vintage curls with a straightener is just as easy to achieve as the classic waves previously mentioned.

That will leave you with perfect Old Hollywood curls without the hassle of pinning and curling.

The best part about this classic style is that it’s a great option for second-day curls.

Make a loose “S” shape for beachy waves

Beachy waves are the ultimate cool-girl hairstyle.

Then, unclamp the straightener and make the same shape, but towards you this time.

The first step to gettingcrimped hairis to braid your hair into sections.

Let your hair completely cool, and then undo the braids.

You’ll have a mass of crimped hair.

If you want small, ’80s crimps, make your braids really small.

If you’re looking for a more wavy crimp, just make your braids a bit thicker.

The thicker you go, the higher the heat you’ll need to use.

Who knew that one little tool could create so many looks?
