Red hair is often thought of as the most high-maintenance color because, well, it is. But last night, I replaced my low-maintenance highlighted brunette with a deep reddish hue. Don't worry-I have consigned myself to weekly trips to the salon. I opted for the lazy girl's red. My colorist, Ronnie Dieterich of the Ted Gibson salon in New York City, added highlights a few inches from the scalp and a red gloss. He explained that this technique (as opposed to all-over red starting at the root) allows me to go months without visiting the salon instead of having to go in for touch ups every six weeks. With this color, I can let the highlights grow out into an ombré effect and just pop into the salon for a gloss every few months to hold onto the red tint. Since red hair tends to fade the fastest, here are my top tips to keep my new hue vibrant all winter long:

Shampoo wisely. Each time you shampoo,

One of my favorite 30 Rock lines is when, in frustration, Liz Lemon calls Jack and Tracy "the cause of my jawline acne." Ah, if only workplace stress could explain everyone's breakouts. We asked Ranella Hirsch, a clinical assistant professor of dermatology at Boston University School of Medicine, what the alternate causes might be and she gave us a surprising answer.

"Jawline acne could be in correlation with your period-regular hormonal acne-but not always," she says. "There's another common reason: facial hair. Lots of women have hair there. And lots of women tweeze and that causes jawline acne all the time." There is a particular style of tweezing that is especially wrong for the area, says the dermatologist: "People really go to town. Often, the hair is not just sticking out, so it's a picking and tweezing combination-they go digging for a hair."

Oh, hell no. That's what I thought when I recently stumbled on a how-to video for men about how, and why, to wear nail polish. We've all seen guys who lacquer up on occasion, for reasons that probably have more to do with youthful rebellion than wanting to look their best. But according to this promotional clip for a nail polish line called Alpha Nail, coloring your nails is also a good way to pick up women.

I do give the brand props for putting the polish in click-pen dispensers-I'm thinking big man hands aren't the most dexterous with little brushes and goopy lacquers. But I can't forgive them for altering the polish names to sound more masculine. Even if you call it nail armor and describe the colors as Concrete, Smoke, or Gasoline, it's still nail polish.

I may not have Beyoncé's amazing voice (or legs) but we do have something in common: New bangs. The singer debuted her brand new fringe on Saturday night, and the bangs were perfectly styled. If you're also new to the world of fringe, or thinking about getting bangs yourself, here are my top tricks for styling them:

Stock up on dry shampoo. I have fine, straight hair. That means I can get away with not blow-drying my bangs every day. But when left to their own devices, my bangs get stringy and flat by lunchtime. I preemptively mist dry shampoo at the roots in the morning and then massage it through to prevent them from getting piece-y later in the day. I like Oribe Dry Texturizing Spray, which doesn't turn my dark hair white.

We know that going out without slathering on SPF causes sunburns, wrinkles, and skin cancer-but did you know your hair color might also be a risk factor?

According to a new study, scientists say that the pigment responsible for dyeing hair red also plays a role in the accelerated development of melanoma, the most dangerous type of skin cancer. The researchers found that mice with red coloring developed malignant moles even before they were exposed to UV rays. Researchers believe it's the genetic background of redheads that makes them more susceptible to melanoma formation. When they removed the pigment, the mice lost the elevated risk of melanoma, which may mean the pigment itself is carcinogenic. What's more, fair-skinned and redheaded people produce pheomelanin, a red-yellow form of melanin that doesn't protect their skin as well as the melanin produced by those with darker skin and hair colors, making UV

Injecting smile lines and filling cheeks and lips with fat and hyaluronic acid has become so commonplace that some of us consider our twice-yearly visits to the cosmetic doctor as safe as getting a dye job or bikini wax. But a recent review of patient records from South Korea's National University's Bundang Hospital found that improper injection of cosmetic fillers-especially fat, but, in a few instances, hyaluronic acid-caused blindness, or partial blindness in one eye, in 12 patients since 2008. True, that's an infinitesimally small percentage of the hundreds of thousands of filler treatments given each year-but still cause for concern.

To understand how this can happen and how it can be avoided, Allure spoke to Sydney R. Coleman, a Manhattan pioneer of fat grafting and clinical assistant professor of plastic surgery at New York University Langone Medical Center. Patients like the idea of lunch-hour treatments but when it comes to injections of fillers,

Somehow, out of nowhere, it became November, and with November comes cooler days and dryer air. Many of us are suddenly finding our faces a little tight and a lot less glow-y than usual. Are you in the same boat? Time to start looking for a new moisturizer. Keep an eye out for creams that contain at least one (two is even better) of the following ingredients: glycerin, hyaluronic acid, or ceramides. Then, once you've found one you like, get the most out of it by applying it to damp but not dripping-wet skin. Dermatologists agree it's the best way to seal in the moisture that's already there. I've rounded up a few of our staffers' favorites, each one formulated for a different skin concern. Take a look:

For sensitive skin: My skin has always been temperamental, and last year I was diagnosed with mild rosacea. Oddly enough, I also have very oily skin, so I have to be careful to use products that won't make me even

Yesterday, after walking six miles both to and from work, my glutes were at least semi-grateful that Hurricane Sandy had wiped out subway service from Brooklyn to Manhattan. My face, however, was not. It was wind-whipped and dry, and the walk made my Halloween makeup (bunny!) look unintentionally scary. It's too bad I didn't heed the advice I'd gotten from dermatologist Ranella Hirsch just days before....

I'd rung up Hirsch, a clinical assistant professor of dermatology at Boston University School of Medicine, to ask what her patients' number-one skin complaint is in the fall. "Everything is about dryness and if they should be using new products," she said. "People are coming off the summer, and the fall beauty ads makes them think they need to go out and buy a whole new line for the season. But that's not necessarily the solution. You don't want to throw out a whole routine that works for you, just tweak it.
