Why is it so hard to dye over black and red hair?

Look at it this way. If you have some cake icing that was white and you add one or two drops of color to it, it will change almost immediately.

If you have a dark color like deep red icing, you try one or two drops to lighten the deep red to a pink but nothing happnes.

You keep adding the drops until you get a pink and realize you have used the whole bottle of white.

Hair is very similar. I have really dark brown hair, its a few inches past my shoulders.

When I was dying my hair "Blonde" I did it myself and used two whole boxes and probally could have used a 3 one.

I colored one box at a time to help the lightening.

If you do this, do the underside first. That way it will lighten. If you don't it will turn a brownish=blonde, while the rest of your hair is blonde.

If you have any coloring mixture leftover then apply it to the top layer of hair. (not on the roots just yet).

Use other boxes as needed.

A word of wisdom - NEvER EVeR - Perm your hair after you color it. (Grins) this turns hair into wax! Yuck
