The products hair and makeup pros swear by

Revlon Global Artistic Director Gucci Westman's skin radiates good health. Her secret? Keeping it moisturized with holistic skin-care products, such as Dr. Hauschka's Rejuvenating Mask, as well as drinking tons of water. Although she's the go-to artist for superstars such as Cameron Diaz and Demi Moore, she doesn't wear much makeup herself. But when she needs to amp up her look, she swears by Revlon's Grow Luscious Mascara.SHOP NOW: Revlon Grow Luscious Mascara, $5; Dr. Hauschka's Rejuvenating Mask, $53

With her fair coloring, Stefanie Syat, the owner of Pre-Dame Makeup Party, is especially attuned to products that suit her coloring. I go for L'Oréal Voluminous Blackest Black mascara because I need more color than the privileged dark-browed girl, she says. The formula thickens at the root to create volume and the illusion that I am wearing eyeliner. To balance the look, she uses Bobbi Brown Blush in Pale Pink. I love her blushes because they are almost like watercolors.SHOP NOW: Bobbi Brown Blush in Pale Pink, $25; L'Oréal Voluminous Million Lashes Mascara, $7

When he's not on set for a fashion shoot, Brian Duprey is making celebrities like Rachel Bilson and Kristen Bell look even more beautiful. To stay looking fresh himself, he uses Giordano Beauty Satin Skin Oil on his face and hair. It's 100 percent natural and works as well as any department-store moisturizer, he says. For his lips, he swears by Lucas' Pawpaw Ointment, a fermented-papaya-based product from Australia. SHOP NOW: Giordano Beauty Satin Skin, $60; Lucas' Pawpaw Ointment, $15

Victor Paul, the owner of Victor Paul Salon, is known for keeping the manes of the Real Housewives of Orange County looking camera-ready. For both himself and his clients, he loves the Enjoy Conditioning Spray. If I decide not to condition in the shower, I do a quick spritz when I step out, he says. It has a low pH, so it keeps the hair really soft. It's also a great detangler for long hair. SHOP NOW: Enjoy Conditioning Spray, $17

It's no surprise that Jane Iredale of Jane Iredale Mineral Cosmetics is a devotee of her own makeup line. Her top pick is the PurePressed Base powder. It saves me so much time because it's four products in one—a powder, foundation, concealer and sunscreen, she says. For her hair, she turns to a product she first discovered at a heath-food store, Giovanni L.A. Hold Hair Spritz. It conquers the frizz battle.SHOP NOW: Jane Iredale PurePressed Base Powder, $52; Giovanni L.A. Hold Hair Spritz, $5

Nicole Hartmann, fashion director at Schwarzkopf Professional, creates styles for celebs at the posh Privé Salon in L.A. She's also known for her own photo-ready complexion. Her secret? Lancôme Eclat Miracle Face Primer. It goes on smooth, and keeps my makeup in place all day, she says. To add texture to her bangs, she uses the OSiS Shape by Schwarzkopf, which she'd love even if she didn't rep the brand. It gives texture and shine without weighing my hair down.

Whether she's designing Taylor Swift's costume for the AMAs, or dressing Shania Twain for her show in Vegas, celebrity stylist Soyon An does it all—clothing, makeup and hair. Due to her hectic schedule, she relies on low-maintenance beauty products such as Julep's new Freedom Topcoat, which dries without smudging in less than five minutes. Her unique beauty trick, however, is to spray Static Guard on a brush and run it through hair—she says it's a miracle cure for frizz. SHOP NOW: Julep Freedom Top Coat, $18; Static Guard, $5
