If you have fine hair, you know how it feels to style your hair in the morning and have it go limp by noon. These surefire styling ideas put plenty of thick tricks in your beauty arsenal. Today, you have more allies than ever in products that are intended to boost volume.

Naturally, anyone with fine hair should use a shampoo, conditioner and styling products that are formulated to fatten-up fine hair. Volumizing shampoos and conditioners plump-up strands without weighing them down. Avoid heavy gels and go easy on those oils. Try a mousse or shaping hair spray—they’re great lightweight options.

In the a.m., dry and style your hair in two steps. Use the high-heat setting on your blow dryer to get most the water out of your hair. Then apply styling products and begin styling when hair is 80% dry. The more moisture you remove from your hair before you begin styling, the more likely it will hold the style and look full from 9 to 5—and beyond. Also, lift the roots with your brush as you dry. And always use the cool-shot feature on your blower before removing the brush from the section you are drying.

Tired of the morning routine? One of the simplest ways to get root lift and volume that lasts is to let your hair dry on top of your head. The only drawback: this trick requires you have enough time to let hair air dry—usually overnight. To try it: After shampooing, use a wide-toothed comb to remove tangles, working from the ends, up. Then comb through a volumizing mousse. Comb hair straight up, and secure it on top or curve the ends smoothly and clip them in place. You can also create a top ponytail, twist the pony until it buckles back and pin it up. How can you cut down dry time? Cheat by blow drying hair in place when it’s still damp.

Here are more tress-thickening tricks:

• If you want extra volume, start by lifting the roots straight up or out with a round brush, while your head is held upright. This gives you lots more lift than bending at the waist and drying your hair upside down.

• Wear an asymmetrical style? Dry your hair in the opposite direction you want to wear it. Lift the roots one way to dry them, then brush them the opposite way. They’ll lift right up because they are moving against the direction you dried in place.

• Fine hair's worst enemy is humidity. To combat it, remove most the moisture from your hair. Then apply mousse and blow dry. Use a round brush to lift the roots first, then dry the ends. To finish, take a small amount of mousse between your fingers, rub them together and detail the ends. This combats humidity and ends that go limp. Humidity-resistant hairspray also helps prevent fine hair from going limp.

• Hot rollers work great on fine hair, because these change the hair's straight bonds temporarily. Make them work for you by setting hair, then misting on hairspray all over. Let the rollers cool completely, unwind and brush sections from underneath. Rake the roots upward with your fingers to blend the sections. Tip: take sections that are not quite as wide as the roller, never ones that are wider.

• Use a curling iron to add movement and volume post blow-drying. Follow the same rules of hot roller setting: don’t comb through curls until your hair has cooled! If your hair is short, lift just the roots around the iron. Then brush through for blended root lift.

And always ask your stylist to show you how you can style your hair at home. He or she knows your hair intimately and should have several ideas about which tricks will work best with the cut you have.
