FHI Flat Iron Buyer’s Guide

What things to look for when picking a flat iron?

When searching for the perfect flat iron, you might not know where to start. Instead of skimming through FHI titanium flat iron reviews or beauty blogs, start with a look at your hair and the type of styling you’d like to achieve.

In this way, you can determine which iron is the best pick for you and your mane. Some things to consider are the:


First of all, take a look at the materials, paying close attention to the materials that make up the plates. You want to go for flat irons made with quality materials that keep the heat evenly dispersed and seal moisture in.

When it comes to FHI irons, many come with quality plates infused with negative ions that block humidity and tame frizz induced from styling.

Heat Range

Another thing to check for is the heat settings. Different levels of heat work better for different textures. The rule of thumb is, the more course the hair, the higher the temperatures.

Most irons top out around 450⁰F, which could be too hot for finer or thinner hair. Also, in terms of heating, the faster irons heat up, the faster you can style. So, try to find irons with different and adjustable heat settings.


Lastly, take a look at the size. Not only do you need to consider the length but also the width of the iron. Different sizes work better with different styles. Short hair works best with thinner plates that get close to the root.

Longer hair works with any widths though you should stay under 2 inches. Choose smaller widths for tighter curls and larger for fast, quick straightening to achieve the look you want.
