The Finished Look 

Here, the finished look is a voluminous mane with added length and thickness.

Step 4: Long and Luscious

Finally Paves attached a Long Curls Pinup Piece, $24, (Or try Scunci 20-inch Curly Faux Hair clip, $19.99) into the base of the ponytail, between the elastic and where the hair gathered. He fluffed out the piece with his fingers, then applied some hair spray to lock the style in place.

"It's important to incorporate pieces of your own hair as you style the extensions," Paves told us as he took pieces of the model's hair and the extensions and curled them together. Hot tools can be used on human hair extensions but never on synthetic pieces.

Step 2: Build Body

Next, Paves lifted a small section of hair from underneath the ponytail and attached a 1-1/2-inch weft directly beneath it. Bringing the same small section of hair back over the extension, he then attached a second 1-1/2-inch weft above it. This gave the hair more thickness and volume.

Long and Flowing 

Step 1: Add Inches

Ken swept the model's hair back into a half-ponytail and clipped it from rest of her hair. He then parted the remaining hair lengthwise and attached an 8-inch weft from the Put On Pieces Human Hair Clip in Extension 14-inch set, $225, near the part, securing the center clip first, then each side.

Model Before Extensions 

Ever longed for an easy hairstyle change, one that would jazz up your look instantly without months of waiting for your hair to grow? Celebrities feel the same way. That's why they rely on their hairstylists to constantly deliver new looks. How do stylists do it? With hair extensions and hairpieces. And now the rest of us can afford them. "Extensions allow you to test drive a look without commitment by instantly adding length, thickness, and texture to your natural hair style," says Ken Paves, celebrity stylist and creator of Paves Professional hair care line. He's been using extensions for years to give stars such as Jessica Simpson and Eva Longoria sensational styles for photo shoots and red carpets. Now he's joined forces with Hair U Wear, makers of Put On Pieces, a collection of reusable hair extensions and clip-ons made from both real and synthetic hair. They are quick to apply, relatively affordable (natural hair extensions run $225 and up and synthetic pieces run $20 and up), and come in a variety of natural-looking shades to match every hair color.
