Is it better to curl your hair with a straightener or curling iron?

Deciding which tool is best for you depends entirely on your skill level and the hairstyle you’re trying to achieve. Since curling irons offer varied sizes (and sometimes interchangeable barrels), they work best for creating looks like voluminous bombshell curls.

Flat irons can help you achieve curls, beach waves, and so many other styles, but there can be a bit of a learning curve when you’re trying to get the hang of the styling techniques. While beginners might have an easier time styling with a traditional curling iron, all you’ll need is a bit of practice (and a few expert-approved tips) to master flat iron curls.

Which is the best flat iron? 

If you’re surfing the web looking for the best flat iron for you, you’ll see a ton of options. We recommend doing research into which straightener is best for your hair type, length, and hair concerns. Flat iron plates are made with different materials such as ceramic, tourmaline, and titanium. Those with fine hair may prefer the gentleness of ceramic, while anyone with thick, unruly strands may benefit from a tourmaline or titanium hot tool.

There are, however, flat irons that work for every hair type across the board. The L'Oréal Professionnel Steampod Straightener + Curling Iron is a steam flat iron that delivers two times smoother, two times faster* results with less damage. The tool infuses water into the water cuticle with each pass, allowing you to retain moisture as you’re styling. The Steampod also helps protect salon color and adds shine to your hair.

Section the hair.

Before you begin curling, be sure to apply a few spritzes of heat protectant throughout your mane. We recommend the Redken Iron Shape 11 Heat Protectant Spray. This lightweight, thermal heat protection hairspray is perfect for use with flat irons and curling irons up to 450 degrees Fahrenheit to protect your hair, add shine, and reduce frizz. Detangle your mane with a boar bristle brush to avoid any snarls while you’re styling. Be sure to use a detangling product like Biolage All-In-One Coconut Infusion Multi-Benefit Spray before you begin detangling.

Part your hair down the middle and choose which side of your head you want to curl first. Gather a 1-inch section of hair that’s closest to the nape of your neck. Use a clip to keep the top half of the hair out of the way for now.

Crimped Hair

Hint: You don’t need a crimper to achieve this ‘90s-inspired hairstyle. You can also create crimped hair with your flat iron. Starting with dry, detangled hair, apply a heat protectant throughout your mane. Then, apply a quarter-size amount of hair mousse like Pureology Style + Protect Weightless Volume Mousse throughout the mid-lengths to ends of your hair. Separate your hair into eight even sections and create three-strand braids with each section. Craft fewer braids if you want bigger crimps.

Pass your flat iron over each braid, starting by your roots and pressing down on each segment for a few sections until you reach your ends. Wait until your hair cools down before undoing your braids. Complete your look with a few spritzes of hairspray like Redken Triple Take 32 Extreme High-Hold Hairspray.
