Home Dip Dye Tips from http://hubpages.com/hub/Dip-Dye-Hair-Color

If you insist on going it alone, here are some tips on achieving a good home dip dye job.
Take time in picking your two colors. If you're working with your natural or pre-existing base color, your job will be much easier. If you want to do two colors, you may have some trouble with the colors bleeding into one another. Bleeding can be staunched (in a manner of speaking) by using cotton or by separating your colors with foil.
The simplest and probably most error free option for a home job is to try doing a dip dye effect under the outer layers of hair. The outer layers of hair will provide a great natural break effect even if you're a bit clumsy. Dip dye jobs can be precision affairs, especially if you want a 'simple' effect, like the one tone dip dye effect, which looks super easy, but is actually only easy to mess up.
Doing a fringe or bangs is also an easy option for a home job, with fewer opportunities for accidents.
Dip dye jobs are about exploration, vibrant color, rule breaking and most of all - fun. Have fun.
