1. BaByliss PRO Nano Titanium 1 1/4" Straightening Iron
This amazing flat iron is a pro favorite for a few reasons. First, and most importantly, it works. Secondly, when you purchase this flat iron you're also getting a lot of perks. This iron comes with a 4 year warranty, which is almost double the amount of time of most other flat irons on the market. Powerful nano titanium plates effortlessly glide through the hair, LED temperature settings that reach up to 450 degrees make this iron perfect for keratin treatments, and it boasts having the power to straighten hair 40% faster than its competitors. This fabulous falt iron packs a lot of bang for your buck.
Note - The only downside with this flat iron is that the edges are square and not rounded, which makes it more difficult to curl the hair.
2. GHD Classic Styler Ceramic Hair Straightener
Unlike the flat iron listed above, this iron curls as well as it straightens, giving you maximum versatility and control. This flat iron comes equipped with a helpful sleep mode which turns the iron off after 30 minutes of non-use. I know I've been guilty of forgetting to turn of my tools while I've been busy working.
This flat iron has aluminum plates which makes it unsuitable for keratin treatments, but you'll get plenty of other bonuses when you invest in this flat iron. Infrared heat protects your hair with negative ions, sealing in natural oils, moisture and color. A fire retardent outer case protects from the iron getting too hot, and universal voltage makes this flat iron a great option for the hair stylist on the go. Last but not least, a 2 year warranty protects against malfunction.
3. Amika 1.25" Ceramic Styler
If you're a hair stylist that likes to make a statement with your styling tools, then the Amika Ceramic Styler is the flat iron for you.
Never mind that this flat iron works amazingly well, it comes in different colors and styles like zebra, cheetah, snakeskin print and many more. This iron has more than just a pretty face, ceramic plates make it suitable for keratin treated hair, it's ultra lightweight, it can curl and straighten, and it uses infrared technology.
Another bonus - I often see coupons for the Amika website on sites like groupon, living social and lifebooker.com
4. Farouk CHI 1 Inch Ceramic Flat Hairstyling Iron
This flat iron is a top favorite among hair stylists. This tried and true tool can tackle the thickest and unruliest of hair with ease, and it never seems to quit. I've had the same CHI iron for 10 years, and though it has started to act up in the last few months, you gotta give this flat iron an A+ for longevity.
This flat iron has ceramic plates, it curls and straightens, and it comes with a 1 year warranty.
