Finally, I chose the food color because of its bright, bold, crazy look, and another good thing about food colors is that they fade out easily without damaging your hair.
But it also creates a question in mind, How long does food color stay in your hair?
Most of the food colors stay in the hair for 1-3 wash but synthetic food colors last 4-6 weeks. Some tones such as blue, green, and brown have more retention power than red. The longevity of color also depends on the type and color of your hair and washing routine.
Temperature affects the stability of color. Warm water increases the rate of diffusion, the food color dissolves in water and rapidly fades out. Cool water gives the opposite result. Before we proceed further it is necessary to know about the basics of food color.
What is Food Color
Food color is obtained from natural resources. Pigments produced by plants,(carrot beetroot, flowers) are the principal source of natural food colors.
Food colors are basically of three types
1-Natural food colors such as:
Betaine is a magenta dye from beet, Beta carotene is yellow to orange
2-Natural identical colorant:
These are prepared in industries but comes from natural resources
3-Artificial or Synthetic food colors are obtained from petroleum products
For example Indigo carmine blue, Quinoline yellow
These colors are found in different physical states like liquid, paste, gel, or powder form.
Stability of Food Color
Research shows that Red (Amaranth) is less stable than yellow (Sunset Yellow). Whereas the addition of different groups such as sulphonic acid to other food colors decreases the stability of color. These colors are Carmoisine, Sunset Yellow, erythrosine, and Indigo Carmoisine.
The stability of colors is directly affected by temperature. All synthetic colors are more stable such as Ponceau, Allura red, sunset Yellow Tartrazine, chocolate brown, Greenland brilliant blue
At very high temperatures some carbonization may occur which will cause color loss and change of shade. Thus temperature at which the actual shade of color is not changed is called its shelf-life
Is Food Color Permanent or Semi-permanent?
Semi-Permanent colors do not contain any developer(hydrogen peroxide)or ammonia and are less damaging for hair.
All food colors are temporary or semi-permanent dyes. Food color simply coats the color on the surface of hair strands thus it gives an easy-on and easy-off way.
How long does food color stay in your hair?
Usually, the food color stays 1-2 weeks in your hair. Perhaps you think this time duration is too short to choose it but don’t worry all the colors are not washed away at the same rate, More thermostable colors stay longer than less stable colors. Temperature directly affects the color that remains in the hair.
How Long Should Food Color Stay in Hair
There are several reasons which decide the time of stay. The environment does not affect the color but it is a type of hair, color, and washing process that holds color in your lock.
The longevity of color to stay in hair depends on the following factors;
1-Type of hair
Thin and silky hair adopt color for a slightly longer time as compared to thick strong strands of hair. Coating bulky hair is difficult and proves to be a hard task. To solve this issue prepare a thick paste and leave the color for a longer time.
2-Type of color
All synthetic colors are more strong, impart the best and bold hue to hair that lasts long. But natural colors have many positive points like the presence of vitamins, no chemical ingredient, and beautiful scent.
Brown and yellow colors show more retention power and last up to 6-8 weeks.
However red take the top to fade the fastest, Intense red shades fade pretty fast in comparison to auburn, titian red, and more red-brown shades. Because brown hair dye stays longer.
Blue and green colors also stay longer, and gradually fade out with each wash. It may last for 4 to 8 weeks. Sometimes great loss of color occurs during the first wash so it is better to use little water to rinse and avoid shampooing right after dying your hair.
3-Original color of hair
The Virgin color of hair counts much in the stability of color. Different food colors appear differently because outcomes depend upon the original hair color
Food color on a blond or lighter shade
If you are blond or have a light shade you are lucky because food color leaves a visible tint on such hair thus staying longer. Blue changes into green in blond.Red and pink stay in blond for longer than usual. It is hard to remove it but depends on how long you let sit it in your hair
Food Color on Dark Hair
Without lightening the dark hair it is difficult to get desired color shade. For getting an even tone of dark or black hair use green food coloring to counteract red tones or a combo of blue and green to neutralize a reddish-orange hue.
4-How many times do you wash your hair
Food colors are usually washed out in four or five attempts. You should try to wash your hair only once a week. The amount of water also counts, less the amount of water losing less color, the more you flow water to rinse more color washed out.
5-Time to leave dye in
When you are ready to color your hair read the instructions about the time. It may be 30 to 50 minutes. The longevity of color also depends on the time you leave the color paste in your hair. If you could not get the desired shade you may repeat the process the next day.
