3. Sedu Icon Flat Iron

New -Sedu Icon Styling IronThe Lamborghini of Straightening Irons

When it comes to professional flat irons, the Sedu Icon is the cream of the crop.

This amazing flat iron looks professional but weighs in at only half a pound to provide ultimate comfort.

It boasts a digital readout so you never have to guess at the temperature, and it heats incredibly quickly with no recovery time between passes.

This is an expensive one and is the flat iron from Sedu, but it is difficult to put a price tag on beautiful, soft, healthy hair.

Check The Price on Amazon!


  • Bright, bold yellow color stands out and makes a statement.
  • 1″ plates are perfect for most users.
  • Ceramic and tourmaline coated plates create healthy shine with every pass.
  • Lightweight build and ergonomic design make this one of the most comfortable flat irons available.
  • Six temperature controls with a maximum temperature of 450 degrees Fahrenheit.


  • The plates on the Sedu Icon flat iron curve gently, allowing you to create amazing styles with a single tool. Soft curls, ringlets, waves and more are at your fingertips.
  • Unique grips at the end of the flat iron stay cool, even at the hottest settings, allowing you to style in comfort with one hand or both.
  • Sedu backs this flat iron with a three-year warranty.


  • The temperature settings are limited, but the flat iron still works well for almost every type of hair.
  • The recovery time leads the entire industry. No more waiting between passes to straighten!

If you want a top-of-the-line product that will not let you down, the Sedu Icon flat iron is a great choice. It is expensive compared to many of the other flat irons we review, so this is an important consideration.

Although there are flat irons out there that offer you relatively the same features for a much lower price, they are not backed by a three-year warranty and they certainly weigh much more than the ultra-comfortable Sedu Icon flat iron.

Overall, it is a great product, but it will not fit everyone’s budget.
