Thick and Shiny Hair help to modeling career

Soft, bouncy, voluminous tresses can be yours. Here, the latest breakthrough products, tools, and treatments to get the hair you want.

1. THE PERFECT SHAMPOO Living Proof Perfect Hair Day Shampoo and Conditioner ($24 each) can help scale back the number of times you shampoo in a week, thanks to technology that repels dirt and oil by casting an invisible shield around each strand. Why shampoo less? "Wet hair is most vulnerable to breakage," says Tim Rogers, Living Proof's creative director, so the less often you brush and blow-dry sopping-wet hair, the healthier it can grow without splitting. Bottom line: With this duo, your locks becomes smoother and shinier.

2. EASIEST EXTENSIONS Hair extensions can cause severe damage, look fake, or be difficult to attach. But Hair2wear, a line of clip-in pieces ($24–$49) launched with tress-blessed model Christie Brinkley, are a goofproof DIY option that adds instant volume without breaking the bank—or your strands. While synthetic, the extensions (available in 12 hues) blend seamlessly with your natural color, and can be styled with hot tools, washed, and air-dried.

3. MUST-TRY TREATMENT Kérastase's Immunity to Dryness in-salon service ($60) is "a megadose of hydration that leaves hair supple and shiny in 25 minutes," says stylist Nina Dimachki. Unlike other rejuvenating remedies, a moisturizing cream is applied before washing and conditioning, acting as a primer to prevent your shampoo from over-stripping oils needed for shine. And because ends often need extra repair, the four-part treatment finishes with an antioxidant-loaded balm that's especially designed for dull, scraggly tips.
