Curling your hair with a flat iron does not have to involve that awkward twist-and-pull motion that leaves you with one weird kink halfway down the strand. The method in this tutorial uses a simpler four-beat rhythm - wrap, pull, clip, slide - and once you have it down, it works on long or short hair and gives you anything from soft beachy waves to tighter polished curls depending on how much you twist at the end.
The video comes from Kayley Melissa, a long-running hairstyling channel known for clear, slow demos. She walks through the technique with the iron off first so you can see exactly where each finger goes, then runs through the whole head with the iron on. If you have already worked through our French braid walkthrough or our fishtail braid tutorial, this fits right in as the next styling skill to add. For a no-heat alternative that pairs well with curls, see our low bun guide.
You will need a flat iron, heat protectant spray, sectioning clips, a brush, and a flexible-hold hairspray to set the finished look. The whole process takes about 15 to 20 minutes once you get the rhythm.
What temperature to set the iron
Heat is the variable people get wrong, and it is the one that causes damage. Fine, light or
chemically treated hair curls at 250F to 300F. Medium hair wants 300F to 350F. Coarse or very
thick hair needs 350F to 400F and rarely more. If a section is not holding at the right
temperature, the problem is section size or speed, not heat.
One pass per section. A second pass over the same strand does far more damage than a higher
setting, because the hair is already dry and hot when you go back over it.
Why the curls drop out by lunchtime
A curl sets as it cools, not while it is hot. Pulling the iron through and letting the curl
swing free means it relaxes before it has set. Catch each curl in your palm as it comes off the
iron, hold the shape for a few seconds until it is cool to the touch, then let it go.
For curls that last all day, clip each one to your head in a flat coil while it cools and drop
them all at the end. Hair that is even slightly damp will not hold a curl at all, so dry it
properly first.
Curl direction, and why it matters
Alternating the direction of each curl is what separates a styled head of hair from a set of
identical sausage curls. Curl one section away from your face, the next towards it, and keep
alternating. The curls then interlock instead of clumping.
Around the face, curl away from the face on both sides. That one choice opens the face up and
is the difference most people notice without being able to name it.
Plate width changes the curl
A one inch plate is the all-rounder and suits most hair lengths. Narrower plates around half an
inch give tighter curls and reach short hair and fringes that a wide iron cannot. Wider plates of
an inch and a half are faster on long thick hair but cannot hold a tight curl.
The plates need to be rounded at the edges. A square-edged straightener creases the hair
instead of curving it, and no technique gets around that.
Finishing without flattening it
Let everything cool completely before you touch it. Break the curls apart with fingers rather
than a brush, which pulls the pattern out. A light flexible-hold spray from a distance holds the
shape; a heavy one glues the curls into a single mass.
