First you Must have LIGHT hair color otherwise it won't work, then you have to have SUGAR FREE (HAs to be sugar free unless you want a BIIIIIIIG mess) Kool aid. I prefer darker colors like red or blue.
Now take your conditioner and pore it into a bowl. Depending on if you want a full head of color or just high lights you will need from 1/4 cup to 5 cups also depending on hair length. Just use the amount you think you would need to wash your hair out with.
Second pour in your kool-aid. I only used part of the packet because I just wanted one highlight in my hair, but if you want your whole head then you will need the whole packet. MUST BE SUGAR FREE.
I used red.
Mix it. Mix it well.
I added a more dense conditioner because the stuff I first put in was too watery.
this is what mine looked like when I was done.
Now just add to your hair.
For the full hair dye apply to hair then place a shower cap over it and yes you have to sleep in it for it to last. The longer you leave it in the longer it will stay in.
for the highlight look take some tin foil and add to your hair like any other dye. then roll up place something over it because it leaks I found out...(RIP pillow case)
When you wake p rinse your hair out and ta da! All done. Sorry I don't have any pictures of mine, (which turned out really well, well except for the top part didn't dye as dark.) BUt your hair will have a tint of color and is really healthy for your hair. Smells like kool-aid too.
Ask any questions.
