Mix food colors
You need to start with mixing food colors of your choice to create the shade you desire. In order to do so, you will need a base, which can be a clear gel (Aloe Vera) or a shampoo.
-Use a shallow bowl for this purpose and create enough of the paste to cover your head or a section of hair you want to streak.
-The strength of the color will depend on the amount of food coloring you add and the original color of your own hair.
-Thoroughly shake the mixture with a brush until the whole paste is uniform in color and the gel or shampoo is properly mixed.
-If the paste turns out too thick you can always add a few drops of water to keep it fluid for easy application.
Don’t wash your hair just wet them with a little water, making sure the insides and roots are moist. Now partially dry them with a towel to ensure that water doesn’t run out from them and they are left damp. This will help you apply the food coloring properly in the next step.
Apply paste on your hair
Once the food color paste is ready you will need to apply it on your hair using the same brush you mixed it with.
-As a precaution, cover the area under your neck with a cloth so that the food coloring doesn’t drip on your clothes.
-Now apply the paste onto your damp hair, lifting sections to properly coat the underlying layers of hair. Keep at it until your whole head is covered with the food coloring paste.
Let the color set in
Now you need to give time for the color to set in. You can wear a shower cap if you want and keep the hair color on for at least 6 – 8 hours. If you have light or blond hair, you can let it stay on for about 4 hours.
Rinse your hair
After the color has set in properly you will need to rinse your hair with lukewarm water. Be careful not to wash them with shampoo though, because it will wash away the color as well. Just lightly rinse your hair and get out of the shower.
Let them air dry
Don’t rub your hair much or use a towel to dry them. Let them air dry on their own for the best results. Rubbing and patting them while they are wet will weaken the color and possibly leave stains on the towel.
Don’t wash for 3 days
Once your hair dry out, you can style them however you want and enjoy your new hair color. However, you should avoid washing them again for at least 3 days. Generally the color comes off after a couple of washes and will weaken itself over a week’s time.
