Koolaid hair temporary hair dye? 1 1/2 cup of water into a pot, wait untill boiling, then add 1 pack of unsweetened koolaid,( color of your choice.. I chose red.) mix, then pour into a bowl, put your hair in a ponytail and lean your head back! Make sure your hair gets in the bowl. Depending on how much of your hair you want colored is the amount of hair in the bowl. Sit for 10 minutes then dry hair and your done! This was the first time I tried it! Lasts for about a week or two.
