Ever wondered how your hair evolves as you age? We did. So we created our "Hair Age" series where we will examine each decade of a woman's life with super-chic style advice (notice we didn't say the dreaded "age appropriate"), hair-pulling concerns and celebrities who are rocking their manes the best.

If 50 is the new 40, then that goes for your hair too!

Let's look at it this way: By the time you reach your 50s, you can relax a bit more. Your kids may be on their own, your career is solid and at this point in your life, you know who you are. These are all good things because they signal a time of freedom, so have fun with your hair and get a style that is all about YOU.

Style Cues

While lines and wrinkles may not disappear once you stop smiling, celebrity stylist Mark Garrison from his namesake salon in New York says your hair can play a big role in making you look younger. "Bangs great for concealing forehead lines," he says. Above-the-shoulder lengths give your face a lift, layers on top give volume and hair that is angled away from the face flatters your cheekbones. Garrison also says that using subtle highlights to give dimension to your color is a natural and youthful look.

"Hair color for women in their 50s should be somewhat toned down from the hues they were wearing throughout their earlier years," says Nikki Ferrara, colorist at the Sally Hershberger Salon in NYC. For example, if you had pale golden to baby blonde hair through your 20s to 40s, try a shade deeper and keep a warm honey base with some paler golden highlights to frame your face and around your part.

Just remember, at this age you don't have to resort to the short, unshapely and unflattering 'do that your mother had. You can still pull off a style that is vibrant, chic and sexy. That means medium-length hair, loose flowing waves and textured layers will look fantastic. Embrace your 50s and let your hair be a statement to your true self!

Hollywood Hair Icons
When we think of celebrities in their 50s who look downright amazing, of course Madonna, Kim Basinger, Michelle Pfeiffer and Sharon Stone all come to mind. What's great about these women is that their styles have evolved over the years with cuts and colors that flatter their current hair's texture and skin tone which keeps them looking fresh and full of sex appeal.

Your No-Fail Plan
Women in their 50s may be transitioning into menopause. This can change the condition of your hair leaving it dull, brittle and in some cases it can result in hair loss (due to the estrogen depletion). For the first two symptoms there are shampoos that help with this. Ferrara recommends Age Recharge from Kerastase which can bring shine and substance back to the hair with regular use. For hair loss and thinning, there are some supplements and products which may help, but talk with your doctor before spending your hard-earned cash because there are also many things on the market that won't do a bit of good.

In addition, hair that is colored often needs extra care. Use a color-treated shampoo and conditioner, and apply a thermal protector before drying your locks. When styling, Garrisons says a natural texture can be sexy -- just use a crème to define curl and control frizz.

"For women where hair loss is an issue, maybe skip the highlights until your hair makes a turn for the better," advises Ferrara. This also goes for women who are experiencing brittleness. Instead, ask your stylist for a deep conditioner every few weeks. Healthy hair is youthful hair!
