Hi Traco,

One factor to consider is that the donor hair you are getting is Indian which is naturally very dark brown or black to begin with so when you order blond hair, the factory must put the hair through harsh chemical treatments to lift the color. The result is overtreated hair before you even begin to add the dye. Treating it again by adding the color back unfortunately only makes it even worse. See my post about about using fabric dye remover prior to bleaching to lessen the knot bleaching time and unwanted shedding. I have never tried it before but I hear some professionals use this method with EXCELLENT results.
