the EASIEST way.
take unsweetedn cherry coolaid. use a little bowl to add a few drops of water, (literally 1 drop at a time) and mix throughly untill you have a paste, it should be that, a paste, too runny and itll go everywhere...
now give her a quick rinse through, wetting the areas you want dyed, then squeeze out the excess water, you want the hair damp not dripping. now put the koolaid paste on the areas you want tinting. leave on for as long as shell let you, the longer its on the deeper the colour.
then rinse well.
the coulr should last about 2-4 bathtimes before completly washing out, but fades quickly.
its safe, none toxic, and none perminent. the colour isnt as vibrant as say doing manic panic. but it IS safe!
chalk tends to be dusty and go everywhere and blowpens take alot of work.
