You Have To Wash Your Hair Everyday

Although most women don't abide by the 100 strokes a day rule anymore (we hope!) some still follow the everyday wash rule. And we hate to break it to ya, but that "rule" is actually just a rumor. "Your best hair day is usually a day or two after washing," says Aussie celebrity stylist Sarah Potempa. "Our scalps produce oils and the more you wash your hair, the more oil your scalp produces. You won't see results right away, but after a few weeks of washing your hair less, you will notice that these natural oils will distribute more evenly."

You Have To Match Your Manicure And Pedicure

As our favorite Project Runway hosts like to say about some of the designers' work: "It's too matchy-matchy!" This rules applies to nails, too. Don't worry about matching your hands to your toes anymore, these days it's all about mix-matched hues and complementary shades. If you're rocking a gold polish on your hands like Selena Gomez, try a silver or other metallic on your toes.

Redheads Can't Wear Red Lipstick

Redheads wearing red lipstick used to be a major makeup faux-pas, but alas, no more! Christina Hendricks leads the pack of redheaded beauties who rock the rouge lip trend. Celebrity makeup artist Jemma Kidd says to pull off the look, you shouldn't focus on hair color. "Hair Color is irrelevant when choosing the right shade of red--it's skin tone that counts," explains Kidd. "Pink tones are best suited to cooler 'blue reds,' while darker, Mediterranean, and Asian skins are better suited to 'orange reds.'"

You Can't Wear Blue Eye Makeup

After the abundance of blue eyeshadow in the '80s (don't lie, you wore it too) women everywhere were too afraid to wear the cool color out of fear of looking dated. Lucero says otherwise. "Navy and indigo eyeliners are on trend and look really modern when applied as a sexy cat eye," Lucero says. "Stila Stay All Day Waterproof Liquid Liner in Indigo is easy to apply and will last all day. Plus, the indigo shade will make the whites of the eyes appear brighter, resulting in a fresh, beautiful and youthful look." Considering how bright Kerry Washington's peepers look, we'll take Luceo's word for it!

You Can't Wear Flashy Earrings And A Flashy Necklace

Although this rule existed for good reason (too much jewelry and you'll start looking like Mr. T,) there is a way to pull it off. If you're wearing a knockout necklace like Emmy Rossum, keep your earrings proportionate in size. Although she's rocking super sparkly bling on her ears and décolletage, the well-proportioned pieces keep the ensemble looking classy, not trashy.
