Derek Yuen, the man responsible for Cole Sprouse's grown-up new look, recommends the GHD Platinum Professional Performance iron. The flat iron is consistently and evenly heated at 365 degrees, which is safer and less damaging on the strands. “The beveled edges also allow for infinite styling possibilities, not just just for straightening hair,” says Yeun.

Not sure which temperature setting is right for your hair? We recommend starting slow and building up to higher heat settings gradually. Not only will you be able to perfectly identify the optimal heat setting for your hair, but you will also avoid overheating. After all, very few of us actually need upwards of 400° F to see the salon results we’ve always wanted!
Seemingly small details like cord length can make all the difference in the effectiveness of a beauty tool. A longer cord length is desirable here, giving you more freedom and versatility depending on the power outlet situation in your home or your hotel if you're traveling. A cord with 360 swivel capabilities is also a plus. You'll be moving your hair straightener all around your head as you style, and a rotating cord will keep it from getting tangled.
One of the Babyliss’ major drawbacks, and why we only recommend this flat iron for experienced users, is the outside gets hotter than any of our other picks. Hot to the point that it was too hot to hold. One tester said she was “afraid to accidentally touch the top of it.” Others said they could feel the heat against their scalps. At first, another tester said she didn’t mind the heat. This was moments before she burned the top of her hand when it merely grazed the side of the tool.

This lightweight mini straightener is easy to use and great if you love to travel and need to take your tools with you. It's so tiny and portable that it can fit into a carry-on bag, and it heats and is ready to use in only 30 seconds. It packs serious punch, though — its 100% ceramic plates generate six times more negative ions than regular irons for less heat damage and frizz.

Nor does it speak to those of us who work long hours at our job - who support our families and who struggle with issues like how to pay the bills or how to put the kids through college - who have limited time and energy for training - and who are more interested in how to train for lifelong strength and health than in how to gain 30 pounds of muscle in six weeks. 

The ceramic blue plates aren't just pretty; they push conditioners into the hair, quelling frizz 65 percent more efficiently than a traditional ceramic iron. Even experts were impressed. "[It] leaks heat-protective ingredients onto the hair at the exact point of contact, coating every strand during the straightening process," says cosmetic chemist Ni'Kita Wilson.
