Living Proof Satin Hair serum, $29; sephora.com.The Claim: Packed with moisturizing emollients, styling polymers, and the brand's patented molecule OFPMA, this serum smooths hair to make blowouts less of a bicep-burning workout. And since it doesn't contain heavy silicones, which can weigh down strands, it promises to leave locks bouncy whether you apply it while they are wet or dry.
Expert Opinion: "Love it!" says Fugate. "The formula absorbs easily into hair," and when applied before a blowout, "it makes hair shiny and gives it a bit of hold."
Our Take: One staffer worked a handful into thick, wavy, wet strands before hitting them with heat and reports, "It made drying each section much easier. And though it didn't eliminate frizz entirely, the formula is so light, it didn't feel like I had any product in my hair at all." Still, a drop was too much for another tester's dry, fine strands, leaving them "just a tad stringy."Read MoreLess
