Hair color doesn't have to be the usual natural colors of blond, brown or black. Sometimes its exciting to mix it up, especially for a party or event. Blue hair dye has become a favorite hair color ever since the punk movement in the 1970s. As a color typically thought of for aging women, people of all ages are temporarily changing their hair color. Because homemade blue hair color lasts for a few days, it's important to avoid washing your hair after applying the color to keep it looking its vibrant shade longer.
Purchase four packages of sugar-free powdered Kool-Aid Tropical Punch. The blue artificial coloring is what ends up dying your hair. Decide if you want to incorporate another shade like purple by mixing the packages with a grape flavored Kool-Aid package.
Mix two Kool-Aid Tropical Punch packages iin a bowl with two tbsps. of conditioner. Use enough conditioner to cover your entire head or the parts you want dyed.
Add more of the Kool-Aid packages until you get the desired blue color for your hair. Depending on the length of your hair, you may need to use up to four packages.
Apply the mixture on your hair, and make sure it is evenly distributed. Be sure to use gloves so you don't get dye on your hands. Wipe up any mixture on your neck and face with a wet towel.
Blow dry your hair until it is completely dry. Allow for the dye to slowly color your hair for up to 1-1/2 hours.
Wash your hair with cold water to lock in the color in your hair cuticle. Blow dry your hair, or allow it to dry naturally.
Bleach your hair first for a deeper color.
Avoid using mayonnaise as an alternative to conditioner because its thick texture requires you to wash much of the dye out of your hair.
