Heating Technology

First thing to consider when choosing a good flat iron is the heating element on the iron plates. The most popular brands have plates made from titanium, ceramic or tourmaline.

These are the best heating materials which eventually provide a gentler way to straighten the hair since they maintain heat on the surface providing a smoother hair texture with tamed frizz while reducing hair damage.

Technology-wise, through negative ions these one-inch flat irons balance and neutralize frizzy hair by tightening hair’s cuticle.

Plate Size Matters

Flat irons come in different plate sizes and there are reasons that go with it. Plate size ranges from the thinnest half-inch to the wider ones at 2 ¼” width. In this case, ‘bigger’ isn’t better.

A larger plate provides more heat and covers a wider section, but it would do no good when it comes to a small section and it cannot get near the roots. While using the best one-inch flat iron will provide easy maneuvering on hair and an easy glide through each strand.

Design Structure

Another thing to look for is the design. Consider the shape, weight, and feel of the flat iron since you will be using this more often. It best to choose a flat iron that you can easily and comfortably grip. By having a flat iron that you can use with ease, you are able to maneuver through your locks effectively with comfort.

Temperature Control

Different brands of flat irons have a unique heating mechanism and some only have one temperature setting. Put in mind that hair texture varies, there are sections mostly on the front and sides that are finer and fragile while the hair on the innermost section appears to be thicker.

This is due to exposure to various treatments including hair dyes, rebonding, and not to mention exposure to elements.
