METHOD FOR DYEING KERATIN FIBERS

The invention relates to a method for dyeing human hair, having the following steps in the given order: A) mixing a first component (K1) with a second component (K2), thereby obtaining a first mixture (M1), B) mixing the mixture (M1) with a third component (K3), thereby obtaining a second mixture (M2), C) applying the mixture (M2) to the hair, D) allowing the mixture (M2) to react for a period of 30 seconds to 4 minutes, and E) rinsing the mixture (M2) out of the hair, wherein - the first component (K1) is a colorant preparation which contains at least one oxidizing dye pre-product, - the second component (K2) is a dye thinner which does not contain oxidizing dye pre-products or oxidizing agents, and - the third component (K3) is an oxidizing agent preparation which contains at least one oxidizing agent.
