Guide to the best flat iron for thick hair

When you have thick, coarse, and unruly hair, a high quality flat iron is a definite must. Unless you resort to having your hair relaxed frequently, the best way to get naturally sleek and manageable hair is to use a flat iron using the safest, gentlest, yet also powerful straightener.

When you buy yourself an iron, it’s always important to consider your hair type and length. For naturally thick hair, the best irons for you must either be ceramic, tourmaline, titanium, or a combination of any of the three. These provide the best anti-damage results on your hair, and prevent friction, pulls, and snags, that add to heat damage that’s done with regular irons.

The plate sizes must also be taken into consideration – you must choose one with a plate width of at least 1.5” to cover more strands of hair to cut styling time. And lastly, the maximum temperature should be somewhere between 380 to 450 degrees Fahrenheit, so that it’s powerful enough to get the job done of taming coarse and resistant locks.

Of all the quality flat irons out there, these are the best of the best…
