Not oxidizing. Oxidation dye is a hair dye that uses an oxidizing agent (usually a hydrogen peroxide developer) to make chemical changes to the hair. This term applies to permanent and semi-permanent hair coloring. The non-oxidizing dye is just a deposit. The term refers to semi-permanent and temporary spots.
Oxidation occurs when an unstable atom loses an electron, which allows the atom to bond with another element. Hydrogen peroxide oxidizing agent is used as part of hair coloring. Excess oxygen reacts with existing natural hair pigments to create a slight lifting effect.
The blackening is due to oxidation. The top layer of paint is exposed to the air in the bottle. This residual color is safe to use (provided it hasn’t come into contact with a developer) and again should give the same result.
Semi-permanent oxidizing hair dyes Semi-permanent hair products promote high durability of hair color (resistance up to 20 washes), as they consist of a mixture of semi-permanent molecules and hair color precursors. They are generally applied in the presence of hydrogen peroxide and a base such as MEA.
Hair coloring products are generally divided into two categories: non-oxidizing (temporary and semi-permanent) and oxidizing (semi-permanent and permanent).
