Getting your hair color right isn't a science. It's actually quite simple: Stick to colors that compliment your skin tone, figure out if you're better off with single-process color or highlights, and then decide if you're going to pay someone else to do it or do it yourself.
Here are 11 hair color tricks your hair dresser knows; from how to avoid the wrong color to how to do it yourself.
How to Choose the Perfect Shade of Blonde
Some women look good in any color (remember Linda Evangelista?) but most women don't. If you had blonde hair as a kid, you'll likely look good with blonde hair as an adult. If you have pink skin that burns easily, and blue or green eyes, you'll look great with blonde hair, but will need to avoid strawberry shades. If you have sallow skin with yellow undertones, stay away from deep golds.See photos of famous blondes for inspiration.

If you are going the bottle route, never color your hair more than 2 shades lighter than your natural shade.

Can I Go Red?
Almost everyone can go red, what's most important is finding the right shade of red. If you want to go red, I suggest not trying it on your own. Get a professional consultation. You won't believe the number of emails I get from women writing in unhappy when they tried to go "ginger." ("Ginger" means red outside the US.)See this famous redheads photo gallery for color inspiration. Also check out 8 tips to keep red hair from fading and How to pick the right shade of red.
To Color or to Highlight, That's the Question
If you have a great base hair tone, you're better off with highlights. You don't want to mess with nature; what you want to do is enhance it. If your base color washes out your skin tone or is "blah," consider single-process color. Single-process color is cheaper than highlights.Highlights look best when the stylist uses at least two different shades. Ask for more around your face, they can brighten your complexion.
Keep in mind that due to root growth, all-over coloring will need to be touched up every four to eight weeks, while highlights can last up to two or three months. At the salon, ask for a gloss treatment following your color. Gloss makes hair look shiny and healthy.
You're Going for Highlights, But Which Kind?
There are basically 4 types of highlights: basic foil highlights, baliage or "hair painting," chunking or "piecing" and lowlighting.Foil highlights add strands of color to hair. You can get up to 5 different shades in hair to make it look more natural.
Baliage, or "hair painting," allows the stylist to add natural stripes of color to hair in large or smaller swaths. This is best for women with a great base color who want to go just a couple shades lighter.
Lowlighting allows the stylist to add darker shades to hair. This give color more contrast.
Should You Do It Yourself?
Home-color kits have come a long way in the past few years. They are perfect for busy people and those who want cut the cost of professional colorings. (We know of a couple top fashion editors who color their hair themselves).Some great hair coloring kits include:
L'Oreal Natural Match Hair Color 
Clairol Nice and Easy

If You're Going With a Box, Stick With Semipermanent Color
Semipermanent colors wash out after a few washes, whereas permanent colors have to grow out.Some home hair coloring tips: rub Vaseline around your hairline as a protective measure before applying color. To remove after coloring, rub a small amount of cream cleanser and wipe off with cotton balls. Always wear gloves and wrap an old dark-colored towel around your shoulders. Rinse your eyes with water if you get color in your eyes. If you forgot the Vaseline and stained your skin, rub the area with a cotton ball soaked in alcohol-based toner.
Gray, Gray, Go Away, Don't Come Again Another Day
Gray hair can be resilient to hair dye because of its coarse texture. If your hair is less than 15 percent gray, opt for a semi-permanent color that's a shade lighter than your natural color (or matches your color).Many women who are more than half gray opt to dye their hair blonde.

So You Hate Your Color? Don't Strangle the Stylist!
Don't be afraid to go back to the salon and talk to your stylist if you are not pleased with the results. There are all sorts of ways to fix color that's just not right. If you did it yourself with a semi-permanent color, look for a shampoo with "ammonium laurel sulfate" to wash away the color faster.Get more tips on a bad dye job and how to fix it.
Your Color is Gorgeous, Now What?
Once you invest money in a hair color, you should protect your investment with the proper after-color care. Refresh your color by using a color-enhancing shampoo and conditioner once a week. These products deposit miniscule amounts of color into hair. Check out this list of the 8 best hair products for color-treated hair.Uh-Oh. Your Roots Are Growing In
You can expect your color to last about 6 to 8 weeks before roots begin to show. If your hair is colored, get your roots touched up or do them yourself with a store-bought kit. I like Clairol Nice and Easy Root Touch Ups. Be sure and test the color first before applying.If you have highlights or lowlights, you can avoid having your whole head colored by asking your stylist to do your hairline, crown and part. A word of warning: Foil highlights require precise application and fixing dark roots is nearly impossible. Ask about easier to maintain highlighting techniques.
