If you have straight hair:
**Consider bangs They lie perfectly in straight hair and instantly refresh your style, says Ruben Colon of Sally Hershberger Salon in New York City.
**Change up your hair color Highlights or lowlights add dimension and will swell the hair shaft, helping fine, straight hair appear thicker, says Erin Anderson of Woodley & Bunny Salon in Brooklyn, N.Y.
**For stay-put curls Comb a texturizing product into wet hair for grip, then rough blow-dry. Hit sections with hairspray before twirling them around a curling iron; finish with another light mist of hairspray.
If you have wavy hair:
** Avoid blunt cuts They eliminate body and give girls with otherwise gorgeous waves a funny pyramid shape, says Travis Speck of Bumble and Bumble Salon in New York City. Go for layers to maximize fullness.
**Be happy about humidity Moisture in the air actually pumps up waves. On drier days, use a diffuser to boost body, says celebrity hairstylist Harry Josh.
**To curb flyaways Smooth frizz serum on damp hair and wrap it into a tight bun; pin. When dry, take hair down and—voila!—hair will be frizz-free.
If you have kinky hair:
**Keep your ends fresh Don’t be afraid to scrunch in curl cream throughout the day. And if you’re trying to grow out your hair, get a trim every two to three months—go more frequently and you won’t see new length; go less often and your ends might dry out and break off.
**Don’t cut wet hair It’s too hard to tell how extreme curls and kinks will spring back. Always make sure hair is dry and straight before snipping to get a perfect all-over length, says celeb hair pro Anthony Dickey.
**Stay away from pressing combs A lot of women use them to straighten their hair—but they’re super hot and can singe strands, says Miko Branch, co-owner of Miss Jessie’s Salon in Brooklyn, N.Y. A safer way to get a sleek style: Blow-dry with a paddle brush, then smooth hair with a warm flat iron.If you have curly hair:
**Never ever use a brush Your fingers are the only tools you’ll ever need for gorgeous spirals.
**Leave in some conditioner For an extra boost of hydration and a curling aid, just rinse out about 75 percent of conditioner in the shower. You’ll get away with using less styling product—or might be able to skip it all together, says curl expert Ouidad.
**For tons of shine Scrunch a pomade or serum like Jonathan Product Create Curl Curling Serum ($26, beauty.com) into hair.
