If a ponytail is your signature hairstyle, it could be time for a short cut. Luke gives Rachel a Katie Holmes-inspired cut by lopping off eight inches. (Ask for gradual layers in the back for movement and long bangs in front.)

Style tip: Give a cut like this a sexy touch for evening by applying mousse to damp hair, then scrunching with hands while blow-drying. Tousle dry hair with your fingers, then "bump up" or lift roots with a curling iron. Total style time: five minutes.

Rich, eye-catching hair color can make hair look healthier and enhance a new cut. (Before you color, deep condition dry, damaged hair the day before to protect it.) Rona works with the color that's most prominent in Rachel's strawberry-blondish strands -- red. Sticking with a tone that already appears in your hair will make your new color more low maintenance. To achieve a soft yet rich result, Rona adds honey-red to Rachel's hair then breaks up the color by painting on flecks of bright yellow-gold. Find out how to enhance your natural hair color here.

A fast pace can take a toll on the skin around your eyes. Aside from using a great eye cream (find one here), employ make up to revive tired lids. Start by filling in brows, which frame the face. Then conceal dark circles, watch this video for great camouflaging tricks, then finish by applying highlighter or white shadow on your inner eye corners. (Try Yves Saint Laurent Touche Eclat, $40.)

Total time: four minutes.

Nothing warms up the face more than a friendly smile and a pop of color on your cheeks. Blend a pink, luminescent cream blush (like Stila Convertible Color, $20) onto the apples.

"I love it!" says Rachel. "[The haircut] has really shortened my daily routine." And though she rarely wears makeup, Rachel is looking forward to trying Taylor's eye highlighting tips for her next evening shindig. "She made me look less squinty!"
