Select 2-3 packages of Kool-Aid in the color of your choice. Put on an old T-shirt and plastic gloves to prevent stains. Place several old towels within reach on your work surface. Brush out your dry hair until it’s tangle-free. Put your hair in pigtails or a low ponytail.
If you have blonde hair, you probably only need 2 packages of Kool-Aid. If your hair is darker than that, go with 3 packages. You can choose any color you want! Red, blue, and purple are popular options that show up nicely on all hair colors. You can also mix your own custom colors!  For example, try mixing together 2 packages of grape Kool-Aid and 1 package of cherry to get a high-intensity burgundy color.  If you have dark hair, avoid using yellow or orange. You can try green, but you’ll probably get better results with a more saturated hue, like purple or blue. Kool-Aid will definitely stain anything it comes in contact with! Put on an old T-shirt and cover your workspace with newspaper or plastic garbage bags to prevent staining. It’s also a good idea to wear plastic gloves to protect your skin. You will need to squeeze the excess dye out of your hair as soon as you pull it out of the dye bath, so make sure you have several old towels within reach and ready to go! Otherwise, you risk dripping the potent Kool-Aid dye all over the floor or counter. Keep in mind that the Kool-Aid will permanently stain the towels, so use old ones. Kool-Aid dye works best on freshly washed, completely dry hair. If your hair is damp, let it air-dry or blow-dry it before you try to dip-dye it. Use a wide-toothed comb to carefully remove any tangles, starting at the ends of your hair and working your way up to the roots. It will still work if you haven’t washed your hair recently, but it’s important that your hair is dry so that it will soak up the color effectively. You don’t have to do this, but it makes the process much easier, especially if your hair is long. Use an elastic to put thick hair into 2 loose pigtails and let them hang over the front of your shoulders. If your hair isn’t that thick, a low, loose ponytail will be fine. If there’s any hair that you don’t want to dip-dye, go ahead and clip it up and out of the way. For example, if you just want to dip-dye the underside your hair, pull the top half up and secure it with a clip.
