‘Oh you’re so lucky you have such thick hair!’. If you are someone with thick tresses, you have probably heard this more than once in your life. And of course, yes, having thick hair has its benefits, but it also can be a nightmare to deal with. I’m talking 2-hour haircuts, tangles, frizz, broken hairbrushes, and styling tools that just don’t work.
So before you shell out on a product like a hair straightener or curling iron, you want to make sure that it will actually work for your hair. You want one that will do a good job and leave your hair sleek and smooth, without burning it to a crisp or causing any damage.
However, there are so many choices out there on the market that it can be hard to narrow it down or know what to look for. What shape, heat-up time, or price point should you look at?
Lucky for you, hair straighteners have come a long way in recent years, meaning most hair straighteners should be effective, whatever your hair type. Titanium-plated designs tend to heat up more quickly so can be a good choice for coarser hair. At the same time they can be more damaging than ceramic plates.
To make it as easy as possible for you, we have created a list of 10 of the best flat irons that are great for thick hair. We have even compared all the key features for you (temperatures recorded in degrees Fahrenheit). Take a look below and see which one you will choose.

What is the best flat iron for thick hair?
There are various factors to think about when choosing which hair straightener is best for thick hair. You have the option of ceramic or titanium-plated. As well as tools specially designed to reduce frizz, add shine, or style hair. Metal-plated tools heat up faster, and can get more intense heat so they can be better for people with thick hair that is hard to straighten.

Ceramic straighteners, however, can also be very effective and as they heat up evenly. This means you will get very consistent results, and may not have to go over the same areas as many times thus reducing the risk of damage. Check the maximum heat on any straightener, ones with the highest heat may be most effective, but experiment to find the lowest temperature that will work for your hair type. Flat irons with wider plates can also be a good choice for thick hair as they can handle more volume at once and will save you time. Although these can be harder for curling or styling (read about curly hair flat irons).
How to straighten hair with flat iron?
To straighten hair with a flat iron, for best results you will need to section out your hair. For ease, you can clip up your top layers of hair, and work from the lowest layers. Start by making sure your hair is clean and dry. Add heat protector and then start sectioning. Take a small section, comb it out, and then pass the straightener over the hair, following behind the iron with the comb. The higher the heat, the more likely you are to get damaged hair, so try and use the lowest heat possible that will work on your hair.
Is titanium-plated or ceramic-plated better for thick hair?
Many people with thick hair prefer to use the first option as they heat up more quickly, conduct heat better and therefore can be more powerful (read our titanium flat iron reviews here). Ceramic plates, however, retain a more even heat, so produce consistent even results and less likely to cause damage. Some people with thick hair find that their hair is easy to straighten in which case ceramic straighteners should be ok. If your hair is hard to straighten, metal options may be best.
So there you have it. Our top 10 best flat irons for thick hair. Hopefully, you feel more informed about the type of iron you need and have maybe even got your eye on a particular model from the list above. Having thick hair has loads of great benefits, but rather than tying it back you should make the most of it. Soon you will be confident and ready to take on the world with straight, shiny locks!
