The Best Flat Iron of 2018: A Comprehensive Guide

When it comes to achieving sleek, smooth hair, few tools are as effective as a flat iron. But with so many options on the market, finding the best one for your hair type and budget can be overwhelming. That's why we at the Good Housekeeping Institute Beauty Lab put in the hard work to test and evaluate thousands of hair tools every year.

Our latest Beauty Lab test involved measuring over 4,914 heat data points and taking 108 swatch expansion measurements to determine which flat irons and straightening brushes stood out from the rest. We scoured the market to find top-rated products at all price points that catered to various hair types, including naturally curly, wavy, and mostly-straight locks.

One of the key takeaways from our test was that the best flat iron for you will depend on your individual needs and preferences. Some may prioritize high heat settings for faster styling, while others may focus on advanced features like curling capabilities or adjustable temperature controls.

After careful consideration, we're excited to share our top picks for the best flat irons of 2018. Whether you're looking for a budget-friendly option or a premium product with advanced technology, we've got you covered.
