With fine tooth comb, brush that remaining inch over your teased section and start sculpting back, spraying with strong hold hairspray as you mold into shape.4. Slick back the sides of your hair and pin back underneath the ends of the teased section, hiding the bobby pins.5. Twist a couple large sections from the bottom half of your hair around the barrel of a curling iron. Spray with hairspray as needed. See More Kim Kardashian Hairstyles

Jennifer Aniston's long, straight style isn't just for casual looks ... it can also work for a more formal occasion, especially if you want to show off some blingy jewelry. Tips to get this look: 1. Start with completely dry hair, which you've sprayed with leave-in conditioner.2. Choose a Sedu hair straightener that is best for your hair length and thickness, and, working with small, 2-inch sections, use shine spray on your hair.3. Once the shine spray is dry, smooth 2-inch sections of hair in the straightener, gliding the iron down from the root of your hair to the tip. 4. Don't brush your hair after using the straightener -- that's how frizz is born. Instead, use fingers to help hair fall into place, and use a lightweight hairspray to hold your 'do. And, if you're lucky enough to be sporting some ear bling, tuck one side of your hair behind your ear to help show off your sparkly jewelry. See More Jennifer Aniston Hairstyles
