im in 8th grade and we're having a pep rally coming up and i would like to know if any of you would know an effective way to temporarily highlight near-black hair purple without using salon-type dye? even do-it-yourself dye, i can't do; my parents don't want me too, and it would last too long. i just need it purple for one day. i would prefer it shows up purple, but if there's no SAFE way to do that, i guess i'll settle with purple shine... if there's a way to get noticeable purple shine, that would also be greatly appreciated! i also don't want clip-ins because i wouldnt be able to cut them to the right length, they would look tacky on my wavy hair, and they would be too bright for my hair color. i also live overseas, so i don't have any of the stores we have over there in the states, and i don't have the resources to order things online and stuff. please help i really want to show my spirit!
