Check Out the Best Flat Irons for Thick Hair: Do They Really Work as Advertised?


Having a thick hair can be a joy. Just imagine the styling possibilities you can do with all those hair strands in your scalp. It also can tolerate heat pretty well so you can say hair breakage may not be in our vocabulary. Each fiber is built up with three strong layers; the cortex, medulla and cuticle, all of each is rich in protein. While this is the advantage of having thick tresses, it also is the downside. Thick hairs can be stubborn and resistant to hairstyling.

Once in a while you we get that compliment “Oh I wish I have a thick hair like yours!”. Little did they know the struggle we have to go through in styling our hair. They don’t have idea that we have to wake up early to style our hair when we should still be in bed sleeping. Not to mention the wrist fatigue we have to go through in holding the hot tool for hours. And the stiff neck we have to endure in doing your back hair. All those things we do for beauty that only thick haired ladies can understand.

Google searching “Best Flat Iron for Thick Hair” probably took you here. We all want the best for our thick hair. So without further ado, let’s lay down the basics.

How to pick the right flat iron for your thick hair?

⦁  Check the heat adjustments.

According to hair experts, 350F-400F is the ideal temperature range for the heat to work on thick, curly and coarse hairs. Depending on the thickness and porosity of hair, you can even go above. Thus flat irons with range of adjustments can conquer your mane. While our hair pretty much tolerate heat we still have to be careful on using the full heat setting. Every hair has its own elasticity and excessive use of heat can leave a permanent damage.

⦁  Consider your hair condition.

Though our hair has higher tolerance for high heat, this doesn’t extend to all thick hair types. Especially if your hair has recently gone through chemical treatments where strands are on its weakest state. Most of flat irons of today have the advanced technology of ceramic, tourmaline and titanium incorporated into the plates. These elements promote heathy styling as it generates far infrared heat that doesn’t over dry your hair but lacks in that moisture for a shinier finish.

⦁  Width and size of the plate matters.

Since our hair is thick we want to get much portion to get the job done in a matter of time. This is not something we envisage doing with a small platted iron. Consider your hair length and thickness. In general, the ideal width is 1-2 inches. Some iron has even a wider plate that can cater all hair of any length. Also, flat irons are use to style hair. If you are into styling, you may want to opt for an iron that has a wide plate to back your styling precisions.

⦁  Is the price worth the quality?

There’s a lot of flat iron to choose from with the price as low as say $10 up to $500. Consider your budget and weigh its pros and cons. Sure there are lot of great features but does the price justifies the benefits or just another expensive tool with pure marketing glorifications. And indeed there are also lot of inexpensive flat irons out in the market but does it last you for a lifetime? Does it work as advertised?

And this is where we jump in. We will help you find the great bargain. With a lot flat irons being release from time to time, it just doesn’t help isn’t it?

Each product will be cap by what customers are saying about what they love and what they don’t about the features. So be prepared. These flat irons are about to get hit straight from the trenches.
