How does Hayden Panettiere get her lashes so thick and full? She reportedly uses RevitaLash to stimulate lash growth (at $150 a tube, it'd better work!). Another Hollywood lash trend? Professionally-done lash extensions, where a lash stylist glues individual lash extensions to your eyelash hairs. (Sessions cost between $300 and $500 and lashes last about two months.) Wanna get lashes like Hayden, Alicia Keys, Taylor Momsen, Whitney Port, and Beyoncé in a more practical, affordable way? Try a super-plumping mascara like Benefit's BADgal Lash Mascara ($19, sephora.com) or a lengthening conditioner like ModelCo's Lash Boost ($16, sephora.com).
