African American Hair Color
A: Not to sound as though I'm not taking you seriously - because I am - the BEST color for your hair is your natural color. Hair color processes can be hard on the hair, especially for African-Americans whose hair is usually coarse and more porous than the hair of other ethnicities. The hazards of serious damage increase if the hair is relaxed frequently and heat processed often.
Most African-Americans have the darkest possible shade of hair color naturally, and most hairdressers agree that it is unhealthy to attempt to lighten the hair more than 4 to 5 levels. Fortunately, given the darkness of the natural color, it doesn't take much to create a notable change in color.
I would personally recommend that you consider a color that is a few levels lighter than natural, and has a color tone appropriate to your skin color - warmer reds and cinnamon tones for more brown-toned skin, and violet and plum colors for skin that has more indigo tones.
The only time I can see attempting super-light hair colors (like blondes), is if you wear your hair very, very short. I have seen very attractive looks achieved for dark-skinned women by lightening the hair to pale blonde shades and using finger-wave styling techniques. The reason this is more acceptable from a healthy hair standpoint is that with such short hair, should the hair become damaged, it can be allowed to grow out and the damage cut away within a matter of months.
