1. Tourmaline Plates

Don’t worry, we won’t make you say tourmaline three times quickly. You just need to know why it’s important to choose a flat iron made of it. As you’d expect from its name, a tourmaline hair straightener is made from ground tourmaline dust.

This type of flat iron creates negatively-charged ions while it’s hot, using less heat to straighten or curl your tresses than a traditional ceramic one.

As you can imagine, less heat means it’s a gentle approach suitable for use even on colored hair. That explains why tourmaline hair straighteners are also often recommended for dry or brittle hair; hair dye can often weaken the hair shaft.

By using less heat, a tourmaline flat iron helps prevent unwanted color changes too. What it does so well is to straighten the hair, and that’s because of how those negative ions we mentioned earlier (more on them later in the article too).

Thus, you won’t spend time on your hair in the morning only to find that it goes wavy halfway through the day. Many users say the straight style they get with the Megastar flat iron stays that way throughout the day.

All with less work to straighten the hair too because tourmaline is an effective material at straightening, more so than a 100% ceramic flat iron.

Your color will stay vibrant too. For example, fiery red locks stay that way – or whatever wonderful other shade you’re rocking!

2. Diamond Technology

As you may have heard, diamond technology is the latest thing in the hair straightener industry. Essentially, a layer of crushed-up diamonds is infused into the tourmaline plates.

It’s a concept that many of the top brands are embracing. And we’re confident this technology is more than just a fad, given its benefit for all hair types, including dyed hues.

Take the Megastar hair straightener, for example. It is designed to keep in moisture and leave you with silky, soft strands after using the super-smooth diamond and tourmaline plates.

The diamond particles distribute even heat across the plates, which means evenly heating your hair. That helps protect against hot spots on your hair, which risks frying the tresses, not to mention preventing uneven styling results.

As a result, choosing a flat iron with tourmaline and diamond technology can create a smooth style that’s soft to the touch. And it’s not so hot that it’s likely to dull or change the color of your hair.

If you do want to turn down the heat (or turn it up), the Megastar allows you to pick from more than 100 temperature settings. So you’re always in control of your hair.

It can go as hot as 450 degrees Fahrenheit, which is among the top temperatures available for the best hair straighteners today. And the smart design includes a stay cool tip and auto shutoff for your safety.

3. An Ionic Generator

Remember the benefits of negative ions for shiny, healthy hair we mentioned earlier? Now imagine if your styling tool had an ionic generator to boost the production of those ions. Yes, that exists!

Only the best hair straighteners have a built-in ionic generator though; it’s not a feature all of them share. The smooth, luminous locks that you can get while using one applies to color-treated hair just as must as natural.

All at a fraction of the cost of the salon. Plus, you can style your hair in the comfort of your home rather than making a trip to the hairdresser.

As for how exactly these negatively-charged ions work their magic, they counteract the positive ions in your hair while they’re heating your strands. They protect the outside of the hair cuticle, whereas a regular ceramic flat iron only treats the inside.

The first result of babying the outside hair cuticle is little to no frizz. Secondly, the stands look and feel nourished, which is important if you’ve put harsh color on it at home or the salon.

Obviously, the more negative ions, the better. That’s a big reason why we recommend the Megastar for the best hair straighteners for colored hair. It has tourmaline and diamond technology, which produces plenty of negative ions as well as an ionic generator.

The result is not only millions more negative ions than other hair straighteners but hundreds of millions more ions. That’s good news for dyed hair that can be brittle from processing as those ions lock in moisture in the hair shaft. That’s moisture that your colored locks may desperately need now.

Lastly, those extra negative ions in top brands like Megastar reduce risks of the heat of the styling tool damaging the hair. Instead, it increases the chances of silky hair.

Final Words on the Best Hair Straighteners and Colored Hair

By now it’s clear that when you choose a quality flat iron with the features mentioned above, you can use it on color-treated hair with little worry that it will ruin your hair color. In fact, when you choose the Megastar Hair Straightener, you get the nourishment of the ionic generator that might be exactly what your processed hair may need.

Also, this same flat iron has tourmaline and diamond technology, which means it straightens the hair evenly and quickly with less heat than traditional ceramic ones. The result is a gentle approach for your tresses to help safeguard against color fade.

Now you can enjoy not only a beautiful shade of hair but also straight, luminous strands. And look forward to the compliments!
