Many coloring products work in difference ways, but today’s professionals typically use a variation of one of these standard methods:
This temporary hair dye method allows clients to enjoy a new color for a brief period of time before it eventually washes away. Most of these types of products deposit acidic dyes onto the outside of the hair shafts, applying a new color. Some other products actually use tiny pigment molecules that move inside the hair shaft, depositing non-permanent color. What these methods don’t use is ammonia, meaning the hair shafts remain closed during the process. This way the natural hair color remains intact.
Hair lightening, often referred to as bleaching, is often the first step in the process of permanent hair color. Bleach reacts with the melanin in hair shafts, creating a chemical reaction called oxidation that irreversibly removes the color. The reason why most bleached hair turns yellow is because the protein that makes up hair called keratin, is naturally yellow.
Permanent Hair color:
As we mentioned above, most professionals use hair lightening before starting the permanent color to make sure there is a good base to build off of. The process of permanently changing the color of a client’s hair involves using ammonia to open the outer layer of the hair shaft, called a cuticle. Peroxide is used to remove any remaining color and break up the shaft’s chemical bonds, and a new permanent color is deposited into the cortex of each hair strand. Then special conditioners are used to close the cuticles and seal in the new color!
