1.Oxidizing dyes: They are the core components of black hair dyes and are usually composed of organic compounds, oxidants and acidic mediators.
2. Among them, organic compounds can be divided into aromatic and aliphatic ones, which can combine with proteins in hair to achieve dyeing.
3.The oxidant is mostly hydrogen peroxide, which promotes the oxidation of organic compounds into dyes.
4. Acidic media such as acetic acid and citric acid can adjust the pH value to make the hair dyeing effect better.
Auxiliary ingredients: including amino acids, humectants, antioxidants, moisturizers, etc. Amino acids can enhance the binding force between dyes and hair, making the hair dyeing effect last longer. Moisturizers, antioxidants and nourishing agents can protect hair, reduce the damage to hair during the dyeing process and prevent hair from becoming dry and fragile.
