This video correctly shows what cleaning products to use to remove hair dye from carpet. The key to removing the dye is to do it as soon as possible after the spill. The longer it is there, the more likely it will become permanent. Also, I would not recommend flooding carpet with water as is shown. You may end up with an even bigger mess. Might work fine on a carpet scrap- but not on wall to wall carpet in your home. You can't just pick it up and wipe the table underneath it!!
