Can Any Flat Iron Be Used for Thick Hair?

If you are blessed with naturally thick hair, you need to put in extra effort to maintain the volume and the thickness. Taming thick hair can be quite a challenge, and for that reason, not all flat irons will be effective in giving you the style that you want. There are several different varieties of flat irons in the market, each innovatively engineered to meet the specific needs of every hair type.

For thick hair, it's necessary to have a little more heat than normal so that the hair is straightened or styled equally. The types of metal plates that flat irons come equipped with also have different varieties, so it is important to analyze which kind is the best fit for your thick hair.

How to Choose a Flat Iron if You Have Thick Hair

The best flat iron for your hair type requires a bit of research, which, luckily, has already been done for you. A good hair-tool is an investment in your hair and your overall appearance, and if you want sleek, stylish hairstyles, you need to pick the right one. In order to choose the perfect iron for your needs, you need to go over the following features before shortlisting or selecting a model.

Heat Settings

Make sure that the flat iron you select has different heating options and can work at high temperatures because this will minimize your effort, and you will not have to keep heating your strands again and again. This also saves time in the long run.

Observing the Plate Width

When buying a straightener, check the width of the plate. If the plates are too narrow or thin, it will take double the time to style your hair compared to an iron with a thicker girth. 

Selecting the Plate Best Suited for Your Hair

The material that the plate is made up of is very crucial to the performance of your flat iron on your hair. However, there is no 'accurate' plate that you can buy. In addition, it depends on other factors such as the natural attributes of your hair (i.e. curly, wavy, coarse, smooth, etc.). The three most popular plates that flat irons are designed with are usually tourmaline/ionic, ceramic, and titanium plates.

What Recent Buyers Report

This product works like a charm and heats up fast. It comes with a long cord that makes it easier to use at long distances and has a 360-degree swiveling body that makes it a blessing for your hands. Users love that it gives smooth, shiny hair without any frizziness.

Why it Stands Out to Us

This is a spectacular tool because of its nano-titanium technology that conducts a lot of heat in less time, and eliminates frizz and static from hair, taming your unruly hair into sleek, gorgeous locks. Its extensive heat temperatures do not make you go back twice to style the same portion of hair again and is a great tool at a good price.

Who Will Use This Most

This flat iron is designed specifically for those who face frizziness in their hair every time they wash it. It aims to polish your hair and style them without depriving of its moisture so that you end up with a shiny mane each time. It also glides on perfectly without getting in between tangles.

The temperature is easy to adjust, and it comes with a travel case, as well. Consider your hair transformed from those frizzy strands into gorgeous locks in no time!

What Do I Need to Know Before Buying One of These Flat Irons?

Now that you have examined the flat irons we chose to top this list, all for thick hair and some for specific types of thick hair, let's look into the things that you should know before you purchase any of those.

Consider the Shape

Before you get your flat iron, analyze what kind of shape you prefer. If you want a multi-purpose tool that can also curl your hair, analyze the edges of the flat iron to determine whether they are curved, as those are easier to use for curling. Models with sharp edges are often designed to straight hair only and are not as nifty. 

Determine the Plate Width

If you want to get ready quickly every morning, and do not want a multi-purpose tool, then you should opt for the Xtava or Kipozi models, which have wider and thicker plates to style maximum portions of your hair at one time. The thickness of the plates also determines whether your flat iron is travel-friendly, so look into it as well.

Choosing the Correct Plates

If you aren't very aware of the different types of plates, check this out. The three most popular plate styles are made of ceramic, tourmaline, or titanium. 

  • Ceramic plates are used to distribute heat evenly to the hair and are great at retaining heat.
  • Tourmaline plates are more expensive plates, and they are used to repair damaged hair and tone down frizziness.
  • Titanium plates are for coarse and curly hair, and they are pretty lightweight and durable. 

Conclusion

Flat irons can transform your hair and make a shiny, glossy mane or damage your hair because of excessive heat if your hair is too weak. Hence, it is important to determine which kind of model is best suited for your type of hair if you want to see noticeable change and look your best always.
