It's easy to do on any length hair, as long as you have slightly wavy strands, but also works wonderfully for those with super curly strands, too. Start off by applying a firm hold curl-enhancing gel to hair that's still slightly wet. I like Wella Hypercurl ($22), as it gives just the right amount of texture, but without the crunchy results. Then, break out the diffuser — a necessary styling tool that will soften your hairstyle, all while preventing frizz.
For a bit more customization, you can wrap individual strands around your finger to help give the curl more definition. But if you have barely-there waves like me, try scrunching and squishing hair into the diffuser.
