One of the key tie-dye instructions is to not add water to your dye until you are prepared to apply it. It is best to apply dye within 24 hours after mixing. Dye left unapplied after 24 hours will begin to lose concentration and will result in noticeably weaker color intensity.
On most heads of hair, that would mean getting a good 6-8 weeks between touch-ups – but sometimes, even with permanent dye, colour fade can happen within a few weeks. Why does this happen? Typically, hair dyes are water soluble. When you wash your hair, the dye molecules simply dissolve and your new colour rinses away.
