Here are a few tips to help you buy your best flat iron. Splurge on Ceramic Irons Ceramic irons conduct heat better and are less damaging to hair than cheaper metal plates. Metal plates tend to have "hot spots" which can damage hair whereas ceramic plates emit negative ions, which helps to control frizz. Unfortunately, a really good iron will set you back $70 on up. But the investment is worth it. Narrow Plates Means Easier Access to Hard-to-Get Spots Modern flat irons tend to have narrower plates so you can get to spots that are too hard to get to with a large flat iron. Your best bets are 1-inch plates to 1 1/2 inch plates so you can get as close to the crown as possible. Choose a wider plate if you have thick, curly hair and lots of it. Pixies require smaller plates. Aim for a 1/2 inch flat iron. These can be hard to find, but mini flat irons come in this size. You might opt for one of these rather than a full-size iron. Thermometer Gauges & Shut-off Capabilities While some expensive flat irons don't allow you to set the temperatures, you really do want one that does. This is because we all have different hair types and finer, straighter hair does not require the same heat as thickly textured hair does. I like a flat iron that will turn off after a period of non-use. This means I can leave the iron on and not worry that I'm going to burn my bathroom down while I go off to work. How to Properly Use a Flat Iron Now that you've found your perfect flat iron, you'll want to use it properly. Damaged hair from flat irons generally comes from misuse, not the flat iron itself, so read the directions carefully before putting the iron to your hair.
