The 10 Hottest Summer Haircuts

Nothing is more effortlessly sexy than model Chrissy Teigen's loose tumble of textured waves. Blast with a blow-dryer and a round brush for an easy daytime look.

If you love the long look, keep the length but switch up your style with light layers like model Gigi Hadid's signature look. (Before blow-drying, mist a heat protecting prep spray through your strands. Try: Garnier Fructis Sleek & Shine Sleek Primer Style Prep ($4.29 MSRP)

Tons of volume, side-swept bangs, choppy ends; what's not to love about Taylor Swift's new look? If you're thinking about making the cut, invest in a diffuser attachment for your blow dryer and a volumizing foam. Try: Garnier Fructis Full & Plush Root Amp Root Lifting Spray Mousse ($4.29 MSRP)

The bob never goes out of style, but you can elevate the chic, low-maintenance look by following Jessica Alba's angular lead. Ask your stylist to make the front a little longer—an inch or two—than the back.

Iggy Azalea's adventurous dip-dyed tips offer a bright summer update to lob-length hair.

Short cuts are sexy, but, if you're not ready to buzz it all off, opt for a close crop with long bangs. Apply a bit of texturizer on the tips to create separation and definition.

If you were born with a head full of naturally textured, fluffy curls, A) thank your lucky stars, and B) ask your stylist for a quadrilateral bob, like Solange Knowles'. Translation: The roots stay relatively flat while the ends fan out freely.

Leave the hair on top longer than the sides, and have your stylist snip (not shave) the sides close. To style, sweep the front up and back with some touchable-hold hair spray and a gentle tease at the roots, and brush the sides down flat.

For a cut like Rosie Huntington-Whiteley's lob, ask your stylist for light, airy, thin-on-the-ends layers that dust just below the cheeks, chin, and clavicle. Try: Garnier Fructis Full & Plush Thickening Lotion ($4.29 MSRP)

Look closely and you'll notice a few subtle layers snipped into actress Sienna Miller's cute, chin-length cut. Wear it straight, or add a few soft waves.
