Sedu Flat Iron Review & Pictures

Sedu Flat IronWhen left to its own devices, my hair is like a teenager who has the house to themselves because their parents are out of town. It’s Tresses Gone Wild! So that’s why I have to discipline it with the Sedu Flat Iron.

When my CHI Flat Iron died on me several years ago (the on/off button broke), I decided to test-drive a new brand. After doing a lot of research, I opted for the Sedu Pro Ionic Ceramic Tourmaline Flat Iron with the 1.5-inch plates. And it’s lasted me for about 4 years now.

Even though it was one of the most expensive hair-styling tools I’ve ever bought, it’s a purchase I don’t regret. The CHI never made or kept my locks this straight, so I’m a happy camper.

Sedu Flat Iron Review

Before I owned the Sedu Flat Iron or even the CHI Flat Iron, I tried a drugstore variety that was only $20 CAD – it pulled my hair, caused breakage, and didn’t even straighten my hair. Plus my tresses felt super dry like straw. And even with the CHI, I wasn’t fully satisfied with the results.

The Sedu is the top dog – it glides effortlessly through each section of my hair without tugging, and my hair looks glossier while staying straighter for longer.

You may think that spending over $100 on a flat iron is tough to swallow, but the way I see it, it’s the best hair investment I ever made. It truly works, and you won’t need to put a single sticky styling product in your hair to make it work, either.

The thing I love most about the Sedu Flat Iron is that there’s a temperature dial so you can adjust it to suit your hair type. This baby heats up to 400°F, but you don’t need to crank it to the max to see results.

Here are the temperature settings Sedu recommends based on your hair type:

  • 370-400°F (course, very thick)
  • 350-370°F (wavy, curly)
  • 330-350°F (normal, textured)
  • 300-330°F (thin, easy to curl)
  • 240-300°F (fragile, very fine)

I have mine set at around 360°F and use it daily. Surprisingly, it doesn’t completely fry my hair. Of course there is some damage because you can’t avoid it altogether if you’re using it every single day (even if you use a heat protectant spray like the TRESemme Heat Tamer Spray I previously reviewed).

The Sedu Ionic Ceramic Tourmaline Flat Iron is lightweight and feels comfortable in my hands. Plus I appreciate how it literally takes mere seconds to heat up! This is perfect for someone like me who’s always scrambling around in the morning and who doesn’t have much time to spare.

When you turn it on, the green indicator light goes on steady. You’ll know when it has heated up to your chosen temperature because the light blinks.

The 1.5-inch plates are amazing – they speed up the straightening process. (However, if you have very short hair, you should get the regular 1-inch plate instead so it’ll be easier to flat iron all the way to the roots.)

But what really continues to impress me is that it smoothes my hair so well.  With the Sedu Flat Iron, my hair actually looks healthier than the rare time when I don’t use it! This is because it uses special Infra Red Heat Technology that seals in the natural moisture in your hair – this is what gives each strand extra luster.


  • Straightens & smoothes hair
  • Enhances shine & tames frizzies
  • Doesn’t pull or break hair
  • Lightweight
  • Works quickly
  • Has adjustable heat dial
  • Heats up in seconds
  • 1.5-inch plate straightens more hair faster

  • Expensive
  • Hard to find in person (must order online)

Final Verdict: 10/10

Whether you have tight curls and want to set them straight or if your hair is already straight, but you want to reduce or eliminate frizz and make your locks look their best, the Sedu Ceramic Flat Iron is the one for the job!

What do you use every day to style your hair?

      Hey Aubrey!

      Hope you’re loving your Sedu! Since this post, I’ve purchased a GHD flat iron, which is the one that I’m currently using. It works just as well, except for Canadians like myself, a GHD is easier to purchase (because it’s readily available at Sephora stores).
