10 Best Professional Flat Irons: Your Buyer’s Guide (2018)

Amazon

My hair lies somewhere smack dab in the middle of wavy and fuzzy. With the right shampoo, enough hair product, and slow diffusing, I can sometimes coax it into almost ringlet like waves. Other days, I opt for a blowout, and with some fast and hot blow drying, deft maneuvering of a paddle brush and a big round brush, I can get it nearly straight. With the aid of a big barrel two inch curling iron, and 45 minutes of time, it’s almost right. Almost.

Just once, I’d actually like all that effort to result in the silky smooth, shiny, straight hair that you see on those shampoo commercials, or on Hollywood’s red carpet. It’s easier said than done, especially if your mane is thick and coarse, and more akin to German Shepherd than Gisele Bündchen. (I’ve joked about my “dog hair” ever since a stylist offhandedly commented on mine that way.)

Hence, began my search for a salon hair straightener, and my new, much more polite, hairdresser suggested I could work some styling magic with a professional flat iron. My first attempts were pitiful, because, despite her advice, I bought a cheap unit, with plates that were too large and left dents in my hair.

Finally, when I bit the bullet and tried out the best professional flat iron I could afford, the results were nearly miraculous. Now, if only my arms were long enough to reach the ends of my hair, I could easily smooth small sections into long silky strands. But because my hair is down to my behind, the task takes a little more effort and concentration.

Professional flat irons come with many options. My personal favorites are the nano-ionic models, which reduce frizz and leave you with smooth, sleek hair. Ceramic heaters, and titanium infused plates allow you to style with high heat and less damage.

Whichever professional flat irons you experiment with, I do recommend you start with the very best that you can afford. And let me say, the prices vary wildly. If you’re moved to appreciate high priced styling tools, you can spend a couple of hundred dollars on a flat iron. If you’re more motivated by price, some of the most highly rated salon flat irons are under fifty bucks.

Hair straighteners don’t have to cost a fortune, and in the end, with practice, you really can achieve salon-worthy results, without spending the time and big bucks with your hairdresser. Here are my picks for the 10 Best Professional Flat Irons. Get ready to kick your wimpy waves, corkscrew curls and frustrating frizz to the curb.

    • Rated four out of five stars by users
    • Effectively straightens even thick, coarse and curly hair

    The BaByliss PRO Nano Titanium Professional Digital Ionic Straightener with nano titanium technology yields maximum far-infrared heat, penetrating your hair from within, for gentle straightening without damaging your lovely locks. Because nano titanium is an excellent conductor of heat, and maintains stability in ultra-high temperatures, hair straightening becomes fast and efficient.

    The ionic technology, paired with the benefits of pure titanium-plated plates, means you’ll get smooth, sleek styling with less frizz. If you’re looking for a sleeker, smaller straightener that features narrower places, consider the BaBylissPRO Nano Titanium-Plated Ultra-Thin Straightening Iron. Another beneficial trick to protect your hair from hot tools, is to use a heat protection spray. PHYTO SPECIFIC Thermoperfect protects your hair from heat up to 450 degrees.

    To jump start your hair protection efforts, wash your hair first with PHYTO SPECIFIC Ultra-Smoothing Shampoo, and avoid using hot tools on hair that’s dirty or has layers of regular hairspray.

BioCeramic heaters heat up OnePass to 400 degrees Fahrenheit, with instant recovery for smooth results, from roots to ends.

    The plates on this salon flat iron emit natural negative ions, and far infrared energy. They break down surface water clusters into smaller molecules that penetrate deeper, hydrating your hair, removing frizzies, and creating healthy shine.

    Its multi-level heat controller, and nine foot swivel cord make your styling experience easy and specific to your hair type and thickness. All these reasons add up to why we picked it as a best professional flat iron.

    Because straightening your hair works best a section at a time, get some large clips to part out sections. These clips are silicone lined to prevent them from leaving marks in your hair. Protect your bathroom counter top from hot tool damage with the BIO IONIC thermal station mat.

    If you’re just starting out as a hot tool user, it’s easy to occasionally get burns when they’re cranked to their hottest settings.

    The xtava Time to Shine Steam Flat Iron is designed with nano ceramic and tourmaline plates to straighten thick or coarse hair, without over drying the follicles.
