Ever wonder whether those hair tricks you’ve heard about really work or if they’re just old wives tales? We’ve separated myths from realities:

One hundred nightly strokes with a hairbrush will make your locks healthier.
Sleeping Beauty may have spent hours brushing her silky tresses, but in real life, excessive brushing causes split ends and hair breakage, says Mauricio Ribeiro, a hairstylist at B2V Salon in West Hollywood, Calif. Don’t lay off the brush altogether, though; a minute of bedtime brushing distributes natural oils from roots to ends, helping you avoid an oily scalp and dry tips. Ribeiro recommends using a paddle brush with synthetic and natural boar's hair bristles for optimal grooming. The nylon bristles grip the hair, and the natural ones impart shine.

A half-inch trim makes your hair grow faster.
This is a common misconception, according to Allen Edwards, hairstylist to such celebs as Brooke Shields and Kirsten Dunst. A trim won’t boost growth; however, it will eliminate split ends. And since the average head of hair grows at a rate of about half an inch a month, it won't take long for the length to return.

Fresh lemon juice plus sun equals natural sun-streaked highlights.
While the juice of a fresh-squeezed lemon will subtly lighten your locks in the sun, the combination of the lemon’s acidity and damaging UV rays will dry out your hair and may even make it brittle enough to break, says Ribeiro. Instead, use an easy brush-in home highlighting kit or have your colorist add subtle highlights. A few streaks placed in the areas where the sun would naturally hit, like the bangs and small pieces around the crown, will create natural-looking sun-kissed tresses. 

Mayonnaise can double as a great deep-conditioning mask.
Yes, the oil, egg yolks and vinegar in mayonnaise will serve as an organic, natural conditioning treatment, says Diana Schmidtke, a Los Angeles-based hairstylist who has worked with George Clooney and Josh Duhamel. Distribute the mayo evenly through your hair with a wide-tooth comb, cover your mane with plastic wrap and leave it in for 15 minutes. To help the mayo penetrate the hair shaft, run a blow-dryer over your hair for the last couple of minutes, making sure not to overheat the plastic wrap. Shampoo immediately afterward.

Sprinkling baby powder on thin, limp locks revitalizes a flat head of hair.
"This is one of the oldest tricks in the book," says Schmidtke. The powder will absorb hair oils and return a bit of volume to your mane. To avoid looking like Marie Antoinette, be sure to use only a pinch of powder. Or check out the aisles at your local beauty supply shop for colored powders.

Pull out one gray hair, and two will grow back.
"The only thing that will make your hair more gray is worrying about the gray you already have," jokes Edwards. In fact, gray hair occurs when melanocytes, the pigment-producing cells in your hair follicles, stop producing pigment. Genetics determine when this will begin to happen. Not a fan of gray? Apply a semipermanent color that lasts for six to 12 shampoos.

A cold rinse after shampooing leaves your hair shiny.
Yes, you can shiver your way to shinier tresses, says Christopher Dove, co-owner of The Doves Studio in Santa Monica, Calif. Cold water flattens the hair cuticle, creating a smoother, more light-reflecting surface. 

Sleeping on a silk pillowcase will decrease hair frizzies and keep your blowout intact.
It can certainly help. “A silk pillowcase won't absorb your hair’s natural oils or mat your hair while you sleep,” says Schmidtke. “So your style will have more staying power.”

Have you ever turned green with envy when you spotted a woman with gorgeous gleaming hair? Most of us have. But rather than wishing those shiny tresses were yours, here’s a better idea. Learn the secrets of women with high-gloss hair, and you can amp up the luster of your own locks.

1. Women with shiny hair don’t play rough. To create silky shine, treat your hair like fine silk. Use only a wide-tooth comb to detangle wet hair. When you step out of the shower, blot -- don’t rub -- your hair with a towel. Cut down on brushing to avoid fraying strands. “Use the minimum number of brush strokes it takes to achieve or refresh your style,” says Jeni Thomas, a Pantene research scientist on hair and scalp health. Look for a brush that has seamless bristles. “These bristles won’t inflict damage the way bristles with rough surfaces can,” says Thomas.

2. Women with shiny hair use heat tools with care. Protect your hair from being damaged by the high heat of blow-dryers, curling irons and flat irons by coating towel-dried strands with a thermal-protectant product. Always use the nozzle attachment on your dryer. “The coils on dryers are so hot you can literally fry your hair if you place the dryer right against your hair,” says Giovanni Mele, artistic director and owner of Philadelphia’s Giovanni & Pileggi salon. “Without a nozzle, you’re delivering heat and air in all directions, and that can leave your hair frizzy rather than smooth and shiny.” If you’ve been using the same hot tools for the last decade, consider an upgrade. New technology, such as ceramic flat irons and ionic dryers, speeds styling time and reduces the static electricity that causes flyaways and dullness.

3. Women with shiny hair keep their tresses well-hydrated. Shine happens when light bounces off hair’s smooth reflective surface, which means you want your hair to be less like straw and more like ice. Moisturizing shampoos gently remove dirt and product buildup -- which can lead to dull, brittle hair -- and deposit feather-light oils and protein to boost luster. Look for ingredients like dimethicone and aloe vera; they smooth the cuticle and seal water inside the shaft.

4. Women with shiny hair are consistent about conditioning. You don’t need to shampoo your hair daily, but every time you wet it in the shower, applying a conditioner to the ends is essential to keep strands soft and smooth. Once or twice a week, apply a moisturizing mask, then don a shower cap and run a blower over your head for two or three minutes. “That heat helps the treatment ingredients penetrate the hair shaft,” says stylist Steve Lococo, co-owner of B2V Salon in West Hollywood. “That’s why salon treatments always include a few minutes under the dryer.”

5. Women with shiny hair choose styling products that add extra sparkle. Whether you like glossing drops, anti-frizz cream, hair spray, nourishing oil or volumizing mousse, you can find a shine-enhancing version of your favorite styling product. Just avoid your roots and be sure to use a very small amount of product. Instead of applying the styling product directly to your hair, try spraying or spreading a bit on your palms instead and then run them lightly over your hair, section by section.

If you want a gorgeous, easy-to-style and chic new hairstyle, consider the lob. You’ve seen it on your favorite celebs, including Emily Blunt, Heidi Klum, Jessica Alba, Tyra Banks, Anne Hathaway, January Jones, Nicole Richie and Naomi Campbell.

An updated version of the classic bob, the lob falls somewhere between the shoulders and the collarbone. Longer in the front and shorter in the back, it can be worn straight and sleek, tousled or wavy. And it goes easily from jeans to red-carpet glamour. The lob is long enough to be gathered into a ponytail, a loose bun or an updo.

You don’t need to be a star to rock a lob. The cut looks good on almost everybody, says Los Angeles stylist Domingo Serquinia. “The lines are softer than a bob,” he says, “so it flatters every face type. And it can be adjusted to work with any hair texture, save for super curly locks.” If your hair falls in ribbons, a lob will look beachy chic.  But the style can look too boxy or bottom heavy on corkscrew or coiled curls.

Here are some tips from Serquinia, who has been turning out some luscious lobs at Paint Shop Beverly Hills, his hip hair and nail salon.

1. Choose the right lob for your face shape. If you have a square face, long choppy layers at the ends will play down your square jaw. A long face will get a lift with shorter layers. “Midface layers will draw attention to your cheekbones and eyes,” Serquinia says. Keep the lob below your shoulders to lengthen a round face. Longer, side-swept bangs can add angles to a round face, but avoid a blunt fringe.

2. Work with -- not against -- your hair’s natural texture. “The thicker your hair, the choppier you want the ends to be,” says Serquinia. That avoids a bottom-heavy cut and brings some playfulness into the style. But if you have fine hair, those choppy ends will look thinned out. Instead, keep the ends blunt to create fullness.

3. Have fun! One of the great things about the lob is its versatility. You can pull your hair into a high pony and let some of the bottom layers hang out. It’s what Serquinia calls “an unkempt kempt look.” Let your hair dry, and apply a thick leave-in conditioner or wax to play up the ends and layers. Style with a round brush for body, or use a flatiron for sleekness and try flipping up some ends. Experiment with a large-barreled curling iron to create those tousled waves.

As your tan fades and fall approaches, chances are your sun-streaked summer hair could use a little TLC. Follow these hair-resuscitating tips from industry pros and you’ll make autumn the season of gorgeous hair days.

Moisturize, Moisturize, Moisturize
“Summer hair damage isn’t going to just repair itself,” says West Hollywood stylist Mauricio Ribeiro, who operates his own namesake salon. He suggests treating parched manes with a moisturizing shampoo followed by a moisturizing conditioner. Be sure to apply the conditioner where sun-damaged hair needs it most--from the mid-shaft to the tip. “Hair isn’t as dry at the roots thanks to its natural oils, so condition there more sparingly,” says Ribeiro.

Handle With Care
To baby your stressed tresses, apply a leave-in detangler. This will add an extra boost of conditioner and also gently smooth and separate strands, so you won’t have to tug at snags with a comb. That kind of rough handling can add further damage to your hair. “When your hair is wet, only use a wide-toothed comb to prepare it for styling,” says Pantene senior scientist Jeni Thomas. “Even when it’s dry, you want to use the minimum number of brushstrokes it takes to achieve or refresh your style.”

Get Deep
If your locks still look lackluster after using rinse-out and leave-in conditioners, call in the SWAT team: a concentrated hair-conditioning treatment or mask. To get all the benefits from the nourishing ingredients, apply the conditioner section-by-section to your hair, says Dani Hauflaire, a stylist with Maxine Salon in Chicago. Start at the tips and work toward the roots. Then, leave it on for a few minutes while you buff your skin with your favorite body scrub. (Your skin can also use some extra care now!) “The steam from the shower will help the product really penetrate the hair shaft,” says Hauflaire.

Tweak Your Color
Sun exposure can leave your hair looking dull and brassy, especially if it’s color-processed. And the streaks that looked glowing against bronzed skin will wash out fall’s paler complexion. Maintain a flattering balance by adding rich tones to your hair. That means auburn, chestnut, chocolate and coffee if you’re a brunette; caramel, gold and toffee if you’re a blonde. An at-home or salon gloss will also restore shine to your hair so it gleams on even a cloudy fall day.

Cut Your Losses
Chlorine, sun, salt, ponytail elastics -- all can lead to frayed and fried ends. “Left alone, those split ends are going to continue to split,” says Hauflaire. A half-inch trim will make a world a difference -- leaving you with well-defined, healthy ends that will show off your hairstyle, whether it’s a bob, a pixie, straight and sleek or long, sexy waves.

Saltwater, chlorine, surf-side breezes, the warming rays of the sun on a cloudless day … the elements of a perfect summer weekend can play havoc on your locks. But you can still maintain gorgeous hair -- and even get a conditioning boost from the sun with these easy summer hair care tips.

Use Moisturizing Products
Fried hair isn’t just a figure of speech in the summer: It’s a reality. The heat of the sun and the exposure to salt, chlorine and sand will open up the hair’s cuticle, stripping it of natural oils and leaving behind scorched strands. Use shampoos, conditioners and styling products that contain the words “moisturizing” or “hydrating” on their labels.

Shield Your Hair Color
“Just as there’s no such thing as a healthy tan, there’s no such thing as lightening your hair in the sun in a way that’s good for it,” says Beverly Hills hairdresser Jon Patrick. UV rays pull the warmth from color-treated hair, leaving behind locks that are faded and brassy. Even untreated hair can turn dull under the sun’s oxidizing rays.

If you're going to be outdoor during the hours of 10 a.m. and 3 p.m., make applying a hair care product that contains UV filters -- these can be in spray, gel or cream formulas -- as much of a daily habit as applying sunscreen.

Saturate Hair Before Taking a Dip
Drench your hair with clean water before you dive into the pool or the surf. “Your hair is like a sponge,” says Melissa Herst, a stylist at the DiPietro Salons in San Francisco. “If you coat it with clear water, it will soak that in instead of absorbing damaging chlorine or salt.”

Lasso the Power of the Sun
If you’ve ever sat under the dryer for 30 minutes at the salon while good-for-you ingredients soaked into your hair, you know how heat helps a deep conditioning product go even deeper. You can get the same dramatic results by applying a deep conditioner when you’re spending an hour or two at the beach or pool (just pack your favorite conditioning treatment in your beach bag).

Put Down the Heat Tools
With all the heat exposure you’re getting from the hot summer sun, you want to keep your use of hot styling tools to a minimum. “Blow-drying and flatironing your hair usually does not hold up well in the summer heat and humidity, so it’s better to use a styling cream or mousse and let your hair dry naturally,” says Dana Lulgjuraj, a stylist at The Butterfly Studio Salon in New York City. For that sexy beachy look, apply a curl-enhancing spray or cream throughout your hair, allow to air-dry (or speed up the process with a blow-dryer set to medium and a diffuser) and work in a light pomade to keep your hair soft and shiny.

Instead of a curling iron, add body or curl to your hair by using rollers on damp hair, says David Kastin, a senior stylist at the Julien Farel Salon. Let air-dry, then remove.

And remember, accessories can more than make up for less-than-polished tresses. “Get some cool pins and clips and just put your hair up,” says Kastin. “This also minimizes the amount of hair exposed to the sun.”
