Washing without running need help!!

Simplest way is to wash each side separately.

Best way is to dilute the dyes a little before you put them on. This generally doesn't affect the colour (on stronger colours like these) but helps stop a lot of the run off.

Janineb has a great point! Also, maybe try not washing it for a couple of days if you can help it. And when you do wash it, wash separately like stated, and wash in cool water, that way it won't bleed as bad. Good luck!

I have split hair that is white on one side and the other has gone through a few colors though is blue now.  The way I wash mine is putting it into to separate ponies on the sides of my head above my ears.  I get in the shower wash one side all the way to conditioner.  condition and put into a bun.  then I do the same thing on the other side.  From there I rinse the first side and pull up then the other side.  lastly when I get out I wrap it but instead of doing just one twirl I do each side separately then twist together.  I leave this on till it is only damp then I let it airdry.  I have people comment all the time that it is surprising that I dont have bleeding on the super light side.
