(Q&A) What is a good way to temporarilly dye hair for a week?

Q:-
I want to dye my hair for 3 days to a week. How can I do this easily and cheaply?

A:-
go to the salon and ask for a TEMPORARY color. The molecules in the color don't penetrate into the hair and because they're on the outside of the hair they will only last a certain number of shampoos. Do not use a semi-perminent color because 1/2 of the molecules go into the hair and will stay.

I speak from experience.

Or just go to the drug store and get the halloween hair spray that has color in it or get hair mascara.
