Thick hair has the particularity of being difficult to style. Even if it’s not frizzy or curly, thick hair can be stubborn and hard to manage. The secret is to use the right hair straightener. Luckily, there are various types of flat irons on the market. So choosing the best one for you should be easy, right? No, it’s not, because of the numerous options it’s even harder to know which one will work for you. Hence we have made this explicit article in which we discuss what you should look for in a flat iron for thick hair, what are the best flat irons for this hair type and we have also included some tips and tricks. We call best straighteners the ones that have the characteristics to tame the thickest hair in a flash.

Features a flat iron for thick hair should have

  • High heat settings. Coarse or thick hair can be a burden to straighten sometimes, so your flat iron should be powerful enough to tame it. The maximum temperature of a flat iron should be between 370 and 450 degrees Fahrenheit. Our advice is to start at a lower setting and increase as needed to see what is the right temperature for you.
  • Wide plates if you have long hair. With wide plates, it will take less time to straighten as you can go over more sections at a time. You should choose a flat iron with a plate width of at least 1.5 inches.
  • Tourmaline or titanium plates. Ceramic is usually best suited for those with damaged or fine to normal hair. We recommend opting for a tourmaline or titanium straightener because they produce more negative ions which are essential for an effortless straightening. They reduce hair's frizziness and eliminate the static.

Tips and Tricks for Healthy Thick Hair

Best Flat irons for thick hair

Use a deeply moisturizing mask. It can take more time for the moisture to penetrate all the way into the hair shaft because of the thickness so it is recommended to apply a hair mask at least once per weak.

Trim your ends every 6 to 8 weeks. By doing this you make sure to get rid of the split ends and will give your hair a fresh and healthy look.

Be careful with the heat. We all know that too much heat can cause split ends and hair damage. Make sure to use a heat protectant spray or serum every time you need to apply heat and select a lower temperature that works for you.

Avoid blow drying. This takes your hair’s natural oils and makes it more prone to dryness. When you have time allow your hair to air dry.

Brush your hair regularly. Using a brush instead of a comb has more advantages to this hair type. It will help distribute the hair’s natural oils to your ends.

Use leave-in conditioners. Since thick hair can be more stubborn than other types of hair, so to keep it under control it needs more hydration and moisture. Using a leave-in conditioner won’t weight the thick hair down as easily as fine hair.
