Gone are the days of stringy, spaghetti-straight strands. On celebs at least. We mortals still wind up with marinara-ready heads more frequently than we'd care to admit. But that's only because we don't know the tricks of the trade used by the women we see staring out at us from covers and catwalks, right?

Wrong! Starting here. Starting now, with help from celebrity stylist Eli Thomas, the owner of Thomas Chance Hairdressing in Santa Monica, Calif, we're going share tricks on how you can rock these perfect-for-straight-hair sexy celebrity styles by following these cinchy steps.

Lucy Liu

If you want to keep your hair healthy and glossy like Charlie's sassiest angel, Thomas suggests seeing your stylist often for a "dusting," -- or a very minimal trim of your ends. This will help you maintain the healthiest-looking hair without -- gasp -- sacrificing length. Get more tips on copy-catting Lucy Liu's healthy head of hair.

Reese Witherspoon

Reese Witherspoon's super-blonde straight style wowed at the recent Golden Globe Awards and, no wonder, Jake G.'s ex other half has long been known for her shiny, healthy hair. To increase the shine of your strands, Thomas recommends using a nighttime strengthening serum like Kerastase Noctocalm Night Serum, $30. If shine's not your issue, see how to copy Witherspoon's style here.

Blake Lively

Audiences have been ooing and ahing over Blake Lively's hair since "Sisterhood of the Traveling Pants," and for good reason. She can literally do anything with it (okay, maybe not everything) and it looks fab -- like this easy braided hairstyle that requires minimal effort (and works great when you don't have time to shampoo!) Learn how to do the braid.

Amy Adams

Expectant mom Amy Adams is going to be stoked that she has easy-to-manage hair once her baby-bundle arrives. Here, working a sexy side part, the actress proves that straight and simple doesn't have to mean "plain." To recreate this look, Thomas recommends a good blow-out to smooth the hair and keep it close to the scalp. See the rest of the steps.
