Selecting a hair coloring product depends on the color you want, and how long you want that color to last.
Even Asian women's black hair contains no more than 1% of basic black melanin, and it is this colored pigments of melanin produced at the hair root, that determines the final color.
Coloring hair has been practiced since the ancient times, but it wasn't until 1909 when Eugene Schuller, a French chemist, invented a commercial hair coloring that later became a base for L'Oreal line, that the science of hair coloring seriously began its evolution. Today, 75% of American women dye their hair.
There are two main ingredients in hair coloring. Hydrogen peroxide, better known as an element in the developer, causes sulfur loss in the hair, that causes hair to become dull-looking. The other is ammonia, that acts as a lightener, and allows new color to penetrate the cortex of the hair.
There are roughly three types of hair coloring:
1. Semi-permanent color: This lasts up to 6 to 12 washings, and covers up to 50% of grays. This won't lighten hair, because it contains neither ammonia nor peroxide. But this can become permanent on already permed or colored hair.
2. Demi-permanent color: This lasts about 24 to 26 washings. These do not contain ammonia, so the natural pigments are not lightened. This can also become permanent on permed or pre-colored hair.
3. Permanent color: Ammonia and peroxide are both used, and can change dark hair to light hair. The only reversal from this process is letting your hair grow out the new color. A resulting color is a combination of your natural hair color and the bottled shade. This is the only method to permanently cover gray, or go from dark to blonde. Regular touch-ups of 4 to 6 weeks are needed to control the darker roots.
TIPS
Always start with a minimal commitment.
HOW TO MAKE IT LAST
1. Rinse in cool water. The more you wash your hair, the more moisture, thereby color, gets stripped from the cuticle. But rinsing in cool water helps to tighten the cuticle, and allows for longer lasting color.
2. Use a shampoo designed for color-treated hair that helps preserve color longer.
3. Blot your hair dry. Do not wrap it or rough-dry it with a towel.
4. Use a wide-toothed comb to brush wet hair.
5. Avoid over-drying. Blow dry only until hair is almost dry.
