"  With the new year upon us, looking your best is surely one of your resolutions, and getting your hair in good shape is probably on the top of your to-do list. In fact, some of you may even be considering a keratin treatment to tame your curls or minimize your frizz. And the new at-home kits that claim to be safer than salon treatments may be particularly tempting. In the August 2011 issue of Good Housekeeping we reported on these new do-it-yourself keratin kits for home use as safer options to salon keratin treatments, which have been found to contain formaldehyde, a known carcinogen. While our story pointed out that these kits were both less toxic and easier on the wallet, we hadn&amp;#039;t yet assessed how well they actually worked at the time of publication. In the months since the story ran, however, we&amp;#039;ve had a chance to try out three of the at-home brands, to see how easy they are to apply, if they do indeed reduce curl, minimize frizz, and tame or soften hair, and if the results last weeks or even months as they promise to do. Unfortunately, our testers found the multi-step application process required by the kits time consuming and the odor of the keratin formulas particularly unpleasant. But the clincher was that when it came to getting rid of the frizzies and making hair straight, shiny and manageable, these treatments didn&amp;#039;t deliver. Their overall effect didn&amp;#039;t last, even after just one wash. Our advice: Invest time in learning how to make your hair look its best, whether that&amp;#039;s learning to love your curls or honing your blow drying skills. See our stories on how to speed dry your hair. And better yet, for a sleek, straight look, try out our 2010 VIP (Very Innovative Product) award winner, the Remington Frizz Therapy Style Therapy flat iron. The Remington iron minimized frizz and straightened hair well in our lab tests and was also loved by consumers.
