As soon as school was done what did this little munchkin want? To dye her hair again, just like last summer.
We did it with Kool-aid again. Poured 2 cups of boiling water into a bowl with 1 packet of Kool-aid--no sugar added. Give it a good stir and then dip your hair. We only had to hold hers in for a few minutes because she is so blonde. Then we wrapped the dyed tips on foil so it could sit a little longer, about 10 more minutes. We rinsed her hair well and conditioned it. Do not shampoo yet!
Do be sure to dry with a blow dryer. And be careful! for the first day or two you may end up with a little bit of pink on your shirts if your hair gets wet. The dye will gradually fade from the hair over the summer but ultimately we will have to cut the red tips off. It's a fun experiment!
