The flat iron waves frenzy is still going strong, and for good reason: the cool-girl effect it has on every hair type. Still, admiring your favorite celebrity's flat iron waves is OUAI easier than actually attempting to create them by yourself. To clear up a few things you might be doing wrong when it comes to flat iron waves, we brought in an expert: Justine Marjan, celebrity hairstylist to the Kardashian-Jenner family, Olivia Culpo, Ashley Graham, and more.

For starters, it's important to use the right heat tool. Justine's personal favorite heat tool for flat iron waves? "I love the GHD Platinum+ Styler for all hair lengths. Its rounded edges make it easy to create waves and the ultra zone technology keeps the iron heated evenly and consistently so that your waves are the same throughout," she told us. For more tips on (finally) getting the flat iron waves to look exactly like the tutorial, keep reading as Justine shares the flat iron waves hacks she uses daily on her A-list clientele.

1. Prepping the Hair

Whether or not you decide to prep your hair with product will depend on your hair type and texture. Some hair types don’t require product to hold the pattern while some do. For finer, healthier hair, likely you will want to prep the hair with a light hairspray. I suggest the Tresemme Micro Mist Hair Spray in Texture for light hold without stiffness. 

2. Right Product = Desired Effect 

You'll want to choose the right product to prep your hair with if you're aiming for a certain style of flat iron waves (because there are different types). For example, if you're after beachy flat iron waves, prep damp hair with OUAI Wave Spray. For glam flat iron waves, prep with Oribe Superfine Hair Spray. And for soft flat iron waves, prep hair with Tresemme Compressed Micro Mist Hair Spray in Texture.

3. Position and Wrist

I see a lot of girls struggle to get the correct position of the flat iron in their hands. One mistake I notice is gripping the iron too tight so that it doesn’t glide through the hair—avoid this as it can cause heat damage. Another mistake I see often is keeping the iron parallel to the floor instead of alternating the direction the iron is facing. And lastly, avoid keeping the hair in the iron instead of re-inserting it with each bend of the wrist (think of it as turning a doorknob!).

4. The Brush Out

It depends on your desired result if you brush out the flat iron waves but I usually break it up with a wide-tooth comb for a more piecey finish, or will brush it out with a Mason Pearson for a smooth finish.

5. The Missing (Final) Step

Taming flyaways on your flat iron waves will make a huge difference. I love Leonor Greyl Eclat Naturel Styling Cream afterwards to tame frizz, add hydration and separation to the ends. I also use Bumble and bumble Thickening Dryspun Finish Spray for more volume.
