It is my understanding that no matter what color the hair, it is all bleached blonde then died to achieve a standard uniform color.

I have an order for four units on the way but next time around I'm thinking of going all blonde and coloring the whole unit myself to ensure flawless knots. as was done with The Count. I would think that by doing this you wouldn't be adding any undue stress to the hair since the factory wouldn't have colored it the first time around, but on the other hand if it is has already been died by the factory and you are adding more color with a permanent coloring it could potentially reduce the life of the hair.

Debbie would probably be better equipped to field this question.
