Best flat iron for thick coarse hair T3 Singlepass reviews:

“I really like this straightening iron. It's most definitely a one-pass. It has various heat settings. I'm an African American woman with naturally kinky hair. I blow dry my hair straight and then flat iron with this T3 Singlepass. I wash my hair only every couple weeks and I never have to flat iron my hair again during that time. Because this T3 is a bigger iron, I have to use a mini flat iron to press my edges.”

- A.C.


“I have LOADS of very thick hair that is about halfway down my back, and straightening my coarse hair can be a total nightmare. However, this flat iron gets hot fast, and leaves my hair bone-straight, even those extra-wavy portions right at the back and the nape of my neck. The width makes it extra fast to straighten all my hair! And you can even get a nice flip at the ends, despite the 1 1/2" width.”

- Angie


“I was excited to try this flat iron because I have owned several T3 products over the years (i.e. curling irons, hair dryers, etc.) but have never owned one of their flat irons. When pulling this out of the box I noticed the width was a bit thicker than the irons I normally use but I was open to that because I have long, thick, coarse hair that takes a long time to straighten.

This flat iron heats up very quickly. I like to find the balance between the heat needed to effectively straighten my hair and keeping the temperature low enough to minimize damage.

Using this on my hair I thought it performed equally well to other flat irons in this price range. Unfortunately for me a single pass isn't enough, but I didn't expect that based on the type of hair I have. I also found in use I liked the wider straightener a lot more than I expected because it seemed to make quicker work of straightening my hair. I liked that my hair didn't snag on it and that it didn't have a smell when heating up or while straightening my hair. It also did a good job of retaining heat.

Overall, I think this is a good iron as long as your expectations of it being a single pass iron are in check if you have thick, coarse hair (and especially hair like mine that has a wave to it). It's not a one-pass straightener for me due to the texture of my hair, but no iron is and I am very happy with this.”

- Gloria Richardson

Babyliss Pro flat iron for thick coarse hair reviews:

“Great straightener for coarse hair! I like this straightening iron. My hair is pretty curly and coarse but I only had to go over my hair once and it was bone straight. With my other straighteners that was soooo not the case.

This takes me about 15 min as opposed to 45 with the flat irons I've used in the past...It doesn't burn or singe my hair but my hair is thick and healthy so maybe it wouldn't do well for people with thin, brittle, dry or chemically-treated hair.”

- Rena Johnson

Things We Liked:

  • Extra-long plates help straighten thick coarse hair.
  • Nano Titanium technology protects hair from damage.
  • LED temperature settings up to 450F.
  • Easy to change heat settings.

Things We Didn’t Like:

  • Gets too hot for fine hair.

Best flat iron for thick coarse hair RUSK reviews:

“I’d just bought the Rusk Super Freak Dryer and absolutely loved it - so, I ordered this straightening iron from Rusk. WOW! It works great and I love it! I am of Mexican heritage and have very thick/coarse long hair. Some of my strands are thin/thick, some are straight/wavy/curly and this flat iron completely straightens them all. My hair looks amazing and soooo shiny.

This flat iron really makes it shiny! Also, my hair feels very soft and moves so freely now. I am so happy I just purchased the Rusk Being Smooth Hair Creme. Can't wait to get it and try it out too. Overall, my hair feels and looks like I just had it done at a salon. Sooooo happy that I found these great Rusk products. Customer for life!!

As the saying goes - you get what you pay for - and this Rusk flat iron is definitely worth the price.

- Angelina R.

Best flat iron for thick coarse hair Croc reviews:

“Yes, this infrared is a MIRACLE worker for my course, kinky, curly hair!!!”

- Lana McDonald


"My hair stylist recommended this straightener and believe me when I tell you I've tried them all!. I was very skeptical because they have all seemed the same to me. Even expensive ones have turned out to be disappointing.

I have very thick, curly hair and could never get it completely straight without spending a ton of time. The croc is completely different. It straightens my hair like I just left the salon. I LOVE IT!!! I highly recommend it. I know it's a little pricey but it's worth it."

Best flat iron for thick coarse hair HOT TOOLS reviews:

 “I have thick, coarse, intermittently wavy hair. The HOT TOOLS Signature Series Ceramic Digital Flat Iron is a pretty awesome flat iron at the price point. It heats up quickly and really works well in my hair. I think the combination of wider and thicker plates makes a huge difference.

Is it as good as the iron my stylist has? no. But she approves. ;)”

- Dee K.


“I have thick, coarse wavy hair, so I need flat irons for natural hair to get very hot to actually give me pin straight hair. This flat iron does just that! It goes all the way to 450, and does so in a matter of seconds. It honestly fully heats up faster than any flat iron I've had.

The ceramic plates don't leave my hair crunchy or dry feeling, and the 1.5" plate is a MUST if you have long or a lot of hair. The extra half inch of surface area helps speed up the straightening process so much.

I also really like the rubbery purple coating on it, feels nice and gives good grip. The straightening iron also has a swivel cord which also helps easily move around your head.”

- Jasmine

Things We Liked:

  • 2-hour automatic shut-off feature.
  • The buttons are placed well on the tool.
  • When it is off, it flashes a blue light which can confuse.
  • Design allows you to get close to the scalp.

Things We Didn’t Like:

  • It does take a while to cool down.

Best flat iron for thick coarse hair Revlon reviews:

“Apparently my hair is too thick, coarse, whatever. The comb kept popping off this flat iron so it didn't do anything for me and that is why I purchased it. For the comb. The temp?

Well that was like hell hot. So please do not think just because you have thicker hair that you need to turn it all the way up. Because you will baconize your hair. Nobody wants crispy bacon hair. So start low medium and keep the bacon for breakfast on your plate. Not your hair.”

- Darlene S.


“Being mixed with Hispanic and Italian, my hair is extremely thick, coarse and frizzy. This picture doesn’t even show how silky and shiny my hair is after using this tool and I cannot believe how it cut down on my styling time. I was a little hesitant to buy when a lot of other reviews mentioned the comb getting tangled in their hair.

As long as my hair was brushed through ahead of time, I found that the comb attachment worked really well to smooth as it straightened. Literally the best money I’ve ever spent on any hair product. I could not be happier with this flat iron!”

- GoldenGirl 78
