Gather unsweetened Kool-Aid powder, hot water, a bowl, gloves, a brush or applicator, clips, petroleum jelly, and an old towel or shirt
Protect your skin and clothing with gloves, towel, and petroleum jelly along your hairline and ears
Mix the Kool-Aid powder with a small amount of hot water to make a concentrated dye liquid
Wash your hair first and leave it slightly damp
Section your hair and clip it apart
Apply the Kool-Aid mixture evenly to the sections you want to color
Saturate the hair thoroughly for stronger color
Cover the hair with plastic wrap or a shower cap
Let it sit for 15 to 60 minutes, or longer for deeper color
Rinse with cool water until the water runs mostly clear
Avoid shampooing immediately after dyeing
Dry and style your hair as usual
Repeat the process if you want a brighter or longer-lasting result
