Well if you mean literally dirty hair, then you should wash it and then get highlights for best results. But if you mean hair that has mixed colors and bleached spots, you should wait till the dye is out or bleach it out for best results:)
The highlights are permanent and change the color of the hair but the highlights will appear to darken as one's hair grows out in its natural color. The effect of blonde highlights usually lasts about 6-8 weeks before the hair needs dying again.
No Kool aid does not damage your hair. It will wash out in less than a month. it is the least damaging thing you can do to your hair. It is less damaging than hair straightners.
I'm sure you can but you will have to wash your hair to get the dye out anyway so its really not worth it.
