You'll need to start with freshly washed hair that's not weighed down with yesterday's oil. "It's a good idea to use a volumizing shampoo and conditioner in the shower," says hairstylist Nunzio Saviano. "The products are specifically designed to help hair float up and away from the scalp."
Volumizing products give a blowout extra fullness and body. Since it can be difficult to get products down into the roots of hair, Saviano suggests using a volumizing spray at the roots and then working other products like mousse or gel into the rest of the hair. To give thicker hair volume, he suggests using gel whereas lightweight mousse is best for fine hair.

Taking the time to blow dry hair the right way makes a big difference in volume. Starting at the top and working your way down, dry one section at a time using a round brush and a blow dryer. Hairstylist Kristan Serafino says one of the biggest mistakes women make is trying to dry too much hair at once. "If you take a section larger than the width of the brush, it's too large."
Once you’ve finished drying a section, roll it onto a Velcro roller to let it cool. “When you pull them out once your entire head is dry, you’ll be amazed how much more bounce you have,” says Serafino. When you’re shopping for rollers, Serafino suggests reaching for ones that have a metal center. The metal core holds heat better than plastic versions.
To add even more height, Serafino’s secret is dry shampoo. “Most people use dry shampoo because they want hair to feel clean, but it actually provides volume at the roots,” Serafino says. Sometimes dry shampoo can leave a powdery residue; to avoid white spots, spritz the underside of each section (at the roots) instead of all over.
One styling technique that's best to avoid: teasing or backcombing. Since you can't see that area of your head yourself it's difficult to completely conceal the section that's been teased. "Unless you have a three way mirror, or have someone to do it for you, it probably won't turn out well," Saviano says.
