Her beau’s famous coif may have been named one of the “most influential cuts of 2011,” but Selena Gomez is enjoying a little time in the spotlight with her colorful new look. Right before she went on her South African tour, the pop star stopped by Nine Zero One Salon in West Hollywood, CA, to have some multicolored extensions added to her ‘do. “The color selection for Selena was based on her wardrobe for her tour,” says Nikki Lee, the salon’s co-owner. “She wanted to do something fun and different without damaging her hair. The Great Lengths extensions we added in were perfect for this!” When it comes to selecting color for a look like this, Nikki says there are a couple rules to consider. “Don’t choose colors based on your client’s existing shade of hair,” she says. “Instead, make sure to choose colors that will complement her skin tone and go well with her wardrobe.” Also, select shades from the same color family. “Selena decided on all jewel tone colors. If you do too many colors that don’t go with each other, your trendy new hair is no longer trendy—it’s tacky! I wouldn’t recommend adding in more than three colors,” Nikki says.

When it comes to their hair, celebs are the ultimate quick change artists. One day their locks are cropped—a week later, they’re long and flowing. For an instant short-to-long makeover, celebrities rely on extensions, which was exactly what Christina Ricci did when she tired of her chin-length bob. Stylists Nikki Lee and Riawna Capri of Nine Zero One salon in West Hollywood, California got busy and applied a full head of Great Lengths extensions for the star, completing the look with UNITE after care products. They began by sectioning the hair and applying the extensions strand-by-strand at the base of the nape. They continued sectioning the hair and applying the extensions, working up to the crown. Next, they determined the desired perimeter line and texturized the extensions to blend with the natural hair. Christina requested a mid-length, naturally blended cut with a fringe. To style, they sprayed the surface of the hair lightly with UNITE Shina-Mist for weightless shine. Finally, they flat ironed strands, keeping the iron an adequate distance from the bonds since heat can cause them to loosen. Enter to WIN 2 tickets to Unite Global Sessions in San Diego!
