What Should I look for in a Flat Iron?

There are a few things you should consider when purchasing a flat iron. Before you make your final decision, ask yourself:

  1. What type of plates do I need? – Flat iron heating plates are made from a variety of materials including ceramic and titanium. A little research into which type is best for your hair style can go a long way.
  2. Does it include adjustable temperatures? – Hair burns at about 450 degrees F, so you don’t want a flat iron that gets any hotter than that. For thick hair, the idea temperature range is between 380-410 degrees.
  3. Does it shut off automatically? – There’s nothing worse than getting to work and spending the day worrying if you shut off your flat iron or not. If this is a problem for you, look into a flat iron with an automatic shut off mechanism. This will save you from having to worry about your iron, and could possibly prevent burns or fire damage.
  4. What size are the plates? – Flat irons come in a variety of sizes, from 1/2” to 2” in width. Short or thin hair can usually be managed with a small ½” flat iron, but for longer or thicker hair, a larger iron is probably your best choice.
  5. What about accessories? – Some flat irons come with attached brushes or combs that can make straightening your hair easier. On the other hand, they can also get tangled in your hair, causing burns or damage, so it’s important to consider these accessories carefully before purchasing them.

With all the options out there, it can be nearly impossible to choose the right iron for you. For thick hair though, your best option is almost always going to be ceramic plates and a high temperature setting.
