Abstract
The method of oxidative dyeing of individual hair strands includes providing an applicator with a first and second compartment containing an oxidative hair dye composition and an oxidizing agent respectively and respective liquid-permeable inserts. The two compartments are provided with respective product-dispensing openings, which open next to each other into a product-dispensing area. The liquid-permeable inserts protrude somewhat beyond the product-dispensing openings and are made of spongy material, bristles, or a fabric. At least a portion of a hair strand to be dyed is wet with the oxidative hair dye composition and the oxidizing-agent-containing solution from the liquid-permeable inserts so that a reactive hair dyeing mixture is formed on the hair strand. The hair dyeing mixture is worked or massaged into the hair strand by hand. The individual hair strand may be uniformly dyed or dyed in a point-like or spot-like pattern.
