Just like fashion trends change with rising temps, our hair and makeup have to adjust as well. When it's hot outside, I like to get as low maintenance as possible (who am I kidding, I always try to look fabulous in under five minutes) -- that means minimal-to-no blow drying and quick-and-effortless makeup.

It’s time to think beachy hair and bronzy makeup, so let's look to the stars (and I'm not talking astrology -- though if you want to know what eyeshadow aligns with your sign click here) and beauty experts to see what tweaks they make when the temp heats up. Below are a few celeb-inspired looks that’ll carry you through summer.

Jennifer Aniston

Beachy hair queen Aniston always steals the show with her voluminous, just-messy-enough waves. Get the look by spritzing volumizing spray on your roots, and if you need it, thickening lotion on the rest of your damp hair. Read on for the next steps to the secrets behind her hair here.

Jennifer Lopez

J.Lo shows how to rock a faux glow -- with an edgy smoky eye and a classic nude lip. Copy the look by tracing your inner and outer rims with black eyeliner, then smudging brown shadow (try NYX Single Eyeshadow in Dark Brown, $3.50) around the outer corners up to just below your brow bones. Read on for what to do with lids and lips.

Diane Kruger

Model-turned-actress Kruger gets playful with a spring-and-summer-friendly braided halo -- perfect for dressing up (as she shows here) or down.

Molly Sims

Sims shows how to dress up an otherwise natural, beach-babe look with a berry-red lip and lush lashes. See which products to use to steal her look.
