Easy Styling Hack: How to Curl Hair Using a Flat Iron

Who would’ve thought that a hair straightening tool could also be used for making waves? Here’s how.

Did you know that you can curl your hair using a flat iron? It may sound silly, but yes, you can do that! Of course, you can always use hair rollers or heatless hacks like making sock curls. But if you know how to curl your hair using a flat iron, imagine all the hairstyles you can create even if you have just this trusty tool on your dresser. It’s easy, and we’re here to show you how. 

Step 1

Start with clean hair.

It’s fun to experiment with different hairstyles, but not when your strands are caked with dirt, excess oil, and grime. Start with freshly washed hair and use a shampoo that can help make your strands soft and smooth to make styling easy.

Don’t know which shampoo to use? Try TRESemmé Keratin Smooth KERA10 Shampoo. It is formulated with KERA10 Protein Complex that can penetrate your hair up to 10 layers deep. It gives your hair 10 salon benefits in one wash! Aside from making your hair soft and smooth, this shampoo calms frizz, detangles knots, provides heat protection, helps in strengthening your hair, and tames flyaways, among others.  

After shampooing, don’t forget to condition your hair using Keratin Smooth KERA10 Serum Conditioner. Aside from KERA10 Protein Complex, it also has oleo serum that helps in deeply moisturizing and nourishing your hair.  

Once you’re done washing your hair, let it air-dry. You can also use a blow-dryer. Just set it to its coolest or lowest heat setting to minimize heat damage.

Step 2

Clip your hair.

Brush your hair to smoothen and detangle it. Then, divide your hair into two vertical sections. Clip one side of your hair so it stays in place while you curl the other side.

Step 3

Roll your hair straightener.

Get a small section of hair from the unclipped side. Hold your flat iron horizontally, clamp the section of hair, and roll the flat iron towards you. Keep rolling until you reach the mid-lengths of your hair. Then, hold the flat iron vertically and release your strands.

You can make tighter-looking curls using your flat iron. To do this, clamp a section of hair near the roots, turn the hair straightener to the opposite side, and gently glide it along your hair shaft until it reaches the tips. Twist your hair a little bit to make the spiral shape more defined. Do this to all sections of your hair, and that’s it! You can spritz hairspray all over your hair to make your curls last for hours.

5. Soft Loose Waves
