Some people change their hair color as quickly as the wind blows. Making frequent dramatic color changes is fun, but it's not really the best idea. Constant color change can take a big toll on the condition of your hair. Making continual small changes from season to season is the sure fire way to make certain your hair color is always your most flattering shade. It's also the best way to keep your hair healthy and shiny.

Fall is a few weeks away, and it's time to rethink your look. Most likely, you're already checking out the new fall fashions, looking for a new shade of lipstick and blush, even picking a new nail polish color for your toes and fingertips.

You will soon be out of the summer sun. Your complexion will become a bit paler. Your hair color can start to look faded and brassy instead of sun-kissed. This the perfect time to re-evaluate your hair color and make the necessary changes.

No matter what the shade, hair color will look incredibly warm and natural this fall. The natural nuances of the hair will be accented with translucent chocolate, auburn, amber and golden colors and glazes. Opaque colors that make hair look monochromatic, drab or ash should always be avoided. Obvious streaks of color are out. Randomly placed soft color to add dimension, depth and texture are in.

Brunettes
You should stay a brunette. This doesn't mean you can't go lighter or brighter. It does mean you should avoid blond shades. (The one exception to this rule is if your brown hair has gone grey.) This usually means your complexion has also become paler, giving you more leeway to explore dark blond shades. The best examples of brunettes for fall 2009 are Anne Hathaway, Sandra Bullock, Katie Holmes and Demi Moore.

Blondes
You should either look like you were incredibly lucky and were born with your hair color like Kate Hudson, or fake, fabulous and glamorous like Madonna. Whether you are trying to look natural or glamorous, you should always have depth at the roots. This is an insider's secret: Depth at the roots helps to guarantee your new blond hair is always flattering to your skin tone.

Redheads
You can be as light as a strawberry blonde or the darkest shade of auburn. Redheads should always have golden or copper undertones. Picture Lindsey Lohan, now that she has returned to her God-given red hair. Avoid all violets or blue-reds. This is a color for cars, not hair. My favorite redheads for fall 2009 are Isla Fisher, Amy Adams and (my perpetual favorite) Susan Sarandon.

Constant small hair color changes are the key to looking your best. Fall is the time of new beginnings. People are back from vacation, kids are back at school and life is back at full speed. This is the perfect time to reinvent yourself. Remember: Small changes are all you need to make a big difference in the way you look!
