The Best Flat Iron for Damaged Hair: Our Top 10 Picks

If you’re looking for a new flat iron for your damaged hair, you’re probably well aware of the fact that your options can be more than a little overwhelming.

A flat iron is a pretty simple device at its core, two flat plates designed to heat up and clamp down on your hair, flattening it out and making it silky and smooth.

Yet, despite its simplicity, there seems to be an endless number of different ones on the market, all promising the best looking, flattest hair possible. Upon first inspection, flat irons all appear to accomplish the same thing, whether they are $20 or $200. But looks can be deceiving, and the type of flat iron you get is going to depend on your hair.

To top it all off, there is a common misconception that if your hair is damaged from, say, the sun or using heat to style it, then you are out of luck as far as flattening it is concerned.

Instead, you should let the damaged hair grow out. The good thing is you don’t have to wait. You can still style your hair with a flat iron when you use the best flat iron for damaged hair.

With that said, certain flat irons work better for damaged hair. To help you sort it all out, we’ve put together our top ten picks for the best flat irons for damaged hair.

Best Flat Iron for Damaged Hair

The combination results in a flat iron that not only works well on damaged hair but does more than most others to repair that damaged hair.

This hard plastic shelled iron has all of the great features you would expect from professional-grade hair tools, with one big difference. The HSI Professional Glider uses microsensors that no other flat iron uses to regulate temperature and ensure even heat.


The HSI flat iron uses eight strategically placed microsensors to create uniform heat through its tourmaline-infused ceramic plates. They pride themselves on being the only flat iron on the market to use this technology.

While many flat irons on the market need continuous adjustment in the temperature to keep the heat uniform, the use of these sensors makes this iron worry-free. Simply turn it on and set it to the right temperature, and you are good to go.

The tourmaline is sprinkled into the ceramic plates as they are baking during the manufacturing process and are used to protect your hair while you straighten it.
