The Chemicals in Permanent Hair Dye

When you dye your hair, you must apply it in two steps. First is an alkalizing agent, and then comes the oxidizing agent, mainlyhydrogen peroxide. Combined, they help the new color to set into your hair.

Aromatic Amine

The aromatic amine is the primary dye precursor first applied to your hair as the alkalizing agent. Many hair dyes have ammonia as an alkalizing agent.

However, since it has harsh interactions with other chemicals such as chlorine, more hair dye companies have opted for the alternate alkalizing agent, monoethanolamine.

Monoethanolamine

Monoethanolamine smells like ammonia and is clear or yellow. It has anti-corrosive properties to protect your hair during the dyeing process.

Hydrogen Peroxide

Hydrogen peroxide acts as the oxidizing agent to break down the melanin in your hair. As the natural melanin in your hair breaks down because of the hydrogen peroxide, it will become colorless in nature.

As a result, the colors in the dye will shine through as your permanent hair color until you change it or if it fades from growing in new natural hair.
