How to restore the natural color of my hair?
There is no need to tear your hair, if you are not satisfied with the dyeing results! You can use a decolorizing product (classic Blondor) with 9% or 12% oxygenate that will remove the permanent dye from your hair and will discolor it close to your natural color. Use the product according to the manufacturer's instructions.
Do not ever use a Blondor in the form of powder, because it is a strong decolorizing product and will remove not only the synthetic, but also the natural pigments of your hair. It can even remove a part of the melanin, which builds the natural color of your hair!
