To fake fuller-looking hair, women usually start styling their hair while it's damp. But maximizing the volume of your hair really starts in the shower -- and you can bet your ass that the Angelina Jolies and Olivia Palermos of the world start with volumizing shampoo and conditioner.

MarulaOil Light Rare Oil Volumizing Shampoo and Conditioner, $25 each, are a new breed of volumizing cleanser and moisturizer. Most volumizing shampoos and conditioners work by eliminating heavyweight moisturizing ingredients and adding harsh detergents to make hair extra-clean and bouncy. Paul Mitchell's products feature beetroot-derived arginine, an amino acid that's crucial to building strong, full hair. (Compared to other hair types, fine and thinning hair is typically lower in amino acids.) Marula oil adds light moisture to the hair.

Celebrity hairstylist Riawna Capri, whose clients include Julianne Hough and Selena Gomez, loves this shampoo-conditioner duo for fine hair. "MarulaOil Light Rare Oil Shampoo & Conditioner are ideal for creating a natural, lived-in look," she says.

And you thought primer was just that thing you put on your face before makeup... every once in awhile, when you actually have your s&$# together. TiGi Bedhead Big Head Volume Boosting Foam, $23, is a combination primer, volumizer, texturizer and conditioner for your hair. Whereas makeup primers smooth skin for makeup application, this primer coats hair with flexible polymers for fuller-looking strands with a bit of grip.

"The priming agent forms a film about the hair fiber that sets the foundation with light hold," explains TiGi US Creative Director Thomas Osborn, "[and] the texturizer in the formula gives hair fiber-on-fiber friction that builds body." The result: Thin, fine hair appears immediately fuller with mussed-up, sexy texture.

Osborn suggests combining TiGi hair products for maximum, rock-star volume. "Apply Big Head Boosting Foam throughout damp hair from mid-lengths to ends, and cocktail with Queen For A Day Thickening Spray at the roots," he says.

If you don't have time to blow-dry, curl or, hell, even brush your hair in the morning, there's a product to help build body in your fine hair: Redken No Blow Dry Airy Cream for Fine Hair, $24. It speeds up hair's drying time, controls frizz, conditions and creates movement. Not bad for a humble leave-in cream.

"It can seem counterintuitive for a stylist to recommend a styling product that involves nothing more than air-dry," says Rodney Cutler, Redken brand ambassador and owner of Cutler/Redken Salons in NYC. But, he says, "The effortless look is more chic than ever. As a stylist, it's important for me to give a client a great cut and shape so that their hair can dry naturally, and this product is the perfect complement."

If you're the roll-out-of-bed type, apply the cream to towel-dried hair before you to go sleep. Then, twist it into a topknot and secure with a soft hair tie. When you take down your hair in the morning, you'll have natural-looking, frizz-free waves.
