There are no truer words than the adage "time flies." I can tell you from personal experience that the decades slip into each other. And with each new decade, a woman needs to think about changing her style and her hair to keep looking her best. This means always staying ahead of the curve. It's easier to do than you might expect.
In your 30s, beauty maintenance is minimal. This is the perfect time to experiment with your hair color and style. Most women will start to notice some grey hair in this period. Non-peroxide semi-permanent hair color is translucent, making it the perfect solution to make grey hairs look like highlights. It's also the best way to try on a new hair color. Semi-permanent color looks incredibly natural and slowly washes away, preventing harsh roots. (NOTE: Some trace of hair color will remain if your hair is fine or porous.) The 30s are often a time of personal discovery. Most women are giving their all to their careers and/or families. Being busy doesn't mean you don't want to look fashionable. In fact, it's more important than ever to look your best. This is the perfect time to experiment with trends that work with your hair texture and face shape in search of your signature look that is easy to maintain.
Your 40s is usually when hair color is no longer optional. Your hair is beginning to look dull. Sprays of grey hair have probably started to appear. Returning your color to its natural vibrancy is key to looking your most vital. Pick a natural hue; extreme hair colors are harsh and aging. Going a little lighter is often best, but too light will drain the color from your complexion. Bangs and layers are your best friends in your 40s. Hair can be almost any reasonable length. but it should have softness around the face. Side-swept bangs and face-framing layers disguise the onset of a wrinkly forehead and crows feet around the eyes. Hair lengths between the chin and top of shoulders will camouflage a softening jaw line.
Michelle Pfeiffer, Ellen Barkin, Sharon Stone and a long list of other women have proved that 50 isn't old anymore. More beauty maintenance is needed at this age to look as young as you feel. Hair color requires frequent touch ups. There is nothing more unattractive or aging than grey roots. The most flattering hairstyles for women in their 50s are chin-length or shorter. They provide movement and look full. Flat hair is harsh and should be avoided. Dry or brittle hair looks dull. Conditioning your hair should be done frequently. Blow dryers, flat irons and curling irons must be used with care not to damage the hair.
There is a solution to the beauty challenges of every decade. No matter what your age, embrace it. This is the key to looking perpetually beautiful.
