Things To Check Before Buying The Best Flat Iron For Thick Coarse Hair

Thick and coarse hair needs special type of hair straighteners because the texture and thickness of hair strands call for different weight, plate width, and other factors. Read on to know the details before you buy one.

  • Length Of Hair

Although your hair is curly and coarse, the length of it will determine the size of the flat iron you need. For short hair, you need a straightener that is small in size with standard plate sizes. If your hair is long, then you definitely need a larger size flat iron with wider plate sizes.

  • Heat Settings

Thick coarse hair needs flat irons that should heat up to high temperatures between 380 to 450 degrees Fahrenheit. Without high heat, there won’t be much impact on such hair. There are digital flat irons available that allow you to set the temperatures so that you can have glossy and straight hair without damaging them.

  • Material

Flat irons for thick and rough hair should ideally be made from titanium. That’s because titanium can hold the heat longer and more consistently than ceramic ones. Plus, titanium also heats up quicker than ceramic. The ionic charge in titanium flat irons smooths hair faster without going over it again and again.

A combination of tourmaline, titanium, and ceramic also work well for such hair.

  • Negative Ions

Dry, damaged, and thick hair are full of positive ions. To counteract them and tame them, you need a flat iron that produces negative ions. Look for one where the ceramic or titanium plate has powdered tourmaline added to it.

Tourmaline releases negative ions when heated properly, thus addressing the problems of coarse and thick hair.

  • Plate Size

Choose a flat iron that has plate sizes of at least 1.5 inches. This will enable you to hold more sections of your hair within the plates and reduce styling time. A smaller size hair straightener works well only for short hair, spikes, and bangs.

  • Additional Features

Some extra features on flat irons could work better for people with rough and unruly hair. For example, built-in comb teeth and steam help to tame coarse hair more easily. Then there are cordless hair straighteners, which are ideal for those in a rush. For these people, an instant-heat flat iron becomes handy.

Frequently Asked Questions On Best Flat Iron For Thick Coarse Hair

Q: What’s The Function Of Tourmaline In A Flat Iron?

Answer: The tourmaline in a flat iron helps to heat the plates faster and hold the temperature constantly. Hence, you can style your hair without waiting for ages for the plates to get heated up.

Moreover, the uniform temperature throughout the plates means that the sections of your hair that you are styling is getting the same temperature and will give the same shiny and smooth results.

Q: What’s The Benefit Of Slim Plates In A Flat Iron?

Answer: The major benefit of slim plates on a hair straightener is that it allows you to get very close to the hair roots so that the hair looks straight and smooth from the roots to the tips. With plates that are not slim, the roots will likely be left out and your hair will not look evenly styled.

Q: For Thick Hair, Is A Tourmaline Or A Ceramic Iron Better?

Answer: Since the hair is thick and has more volume to tame down, flat iron with titanium plates work better. Titanium heats faster and thick hair needs more heat for deeper penetration and straightening.

Moreover, titanium can hold the temperature at a constant so that more sections of thick hair can be treated for longer.

Q: Can I Use A Flat Iron On Unwashed Hair?

Answer: Unwashed hair is full of dirt, oil, and grime. Applying a flat iron will make your hair unhealthy if they have not been properly shampooed.

Otherwise, heating it will damage it and seal in the oils to create a build-up that’s unhygienic for your scalp. It may even lead to breakouts on the scalp.

Q: How Often Can Hair Be Straightened?

Answer: Hair should not be straightened more than once a day. If you exceed the limit, you are going to do irreversible damage to your hair. The constant heating will take the moisture away from your hair, leaving them brittle and dry. It’s optimum to limit hair straightening to once a week.

You should have breaks from hair straightening and allow your hair to recover and regain its strength.

Q: Is There Any Flat Iron With Anti-Damaging Components?

Answer: Yes, there are some hair straighteners that come with keratin negative ions on them. These not only drive away the static from your hair and thus get rid of frizz, but they also add moisture to your hair and keep them from getting dry and brittle.

There are also special flat irons that work perfectly on chemical-treated hair without causing damage to the hair or the plates.
