If your hair is wavy, the key is to keep it as natural and easy to manage as possible. For Zoe Saldana's easy waves, celeb stylist and co-founder of Salon AKS Susanna Romano suggests twisting hair while wet and letting it air dry. This will create a softer wave with less frizz. Keep strands smooth by applying MoroccanOil to hair while it's still wet.
To get Jessica Biel's textured waves, avoid the blow dryer. Use your hands to twist sections of hair and let air dry. Twist the hair back off the face and pin back away from your face until its dry. You can use a curling balm like Kim Vo Twist to enhance the curl but don't take it to the end of the hair strand, otherwise you'll have a Shirley Temple ringlet look.
For Hilary Duff's effortlessly beachy waves, Susanna suggests using Phyto Sculpting Gel mixed with Phyto Glossing Cream for a beachy styling "cocktail." Run the mixture through hair, twisting and scrunching hair in the palms of your hands as you diffuse. You can also let hair air dry for a more natural look and to cut down on styling time.
For Keira Knightley's chic hair, ask your stylist for a short and straight, almost asymmetrical cut. The easiest and best way to style this look on your own is using your hands. Avoid brushes because of this cut's short length--it can create poodle pouf volume. Finish with Pureology Colour Stylist Cuticle Polisher to create shine and contain frizz.
Rachel Bilson's cute hairstyle is a modern take on a really straight, center-parted look. This cut works best for fine hair but Susanna says it's wise to avoid too many layers--go for an angled, face framing cut instead. Since super-straight hair can tend to look limp, be sure to use a root lifting spray like Living Proof Full Root Lifting Spray to add volume.
To get Reese Witherspoon's sexy straight hairstyle, ask your stylist for a straight cut with bangs. Of all hair types, bangs work best on straight hair. Susanna says that the key to this look is volumizer on your roots but not on the bangs. Blow dry hair with a large, round brush and don't use too much product because it might weigh down your hair.
Jennifer Aniston's signature style is best described as a long, layered, fluid style with a more blunt bottom. To style this cut at home, flip your hair over using a large flat, round brush to elevate the root and use a flat brush on the ends. If you want an extra straight look, finish with a flat iron and a spritz of Umberto Shimmer Shine Spray to add polish.
"Taylor Swift is the perfect example of how you can easily sport curly hair with just a little extra effort," says Susanna. "This style is all about enhancing what you already have!" To style your curls at home, apply a curl enhancer like Nexxus Gorgeous Curls Curl Enhancing Foam Styler, then wrap hair around a 3/4 inch curling iron to create tight, bouncy curls.
When it comes to your curls, less is more--as in the less work you have to put into them, the better. To get Mila Kunis' sultry spirals, dry hair naturally, then take pieces that need smoothing and wrap them around a 1/2 inch curling iron for definition. "Cut down on time by not curling all your locks--this creates a natural, perfectly imperfect curl. It's less time consuming than you think," says Susanna.
Curly girls have a lot of natural volume, so they can pull off super-long, full hairstyles like AnnaLynne McCord's here. To style at home, gather curls together, hand twisting three ringlets into one strand. Pin hair and blast with a diffuser for Susanna's take on a modern-day (much easier!) pin curl.
For a more glamorous, sophisticated look like Sarah Jessica Parker's, Susanna suggests applying Aveda Be Curly Curl Enhancer and then diffusing hair to achieve a fluffy ringlet. Finish the look by curling your strands with a large barrel curling iron and brushing through the curls to soften them.
