Hair oxidizer purpose
Hair oxidizers, also known as developer, are an essential part of the hair coloring process. They are used in combination with hair color or bleach to open the hair cuticles and allow the pigments to penetrate the hair shaft. Without an oxidizer, the hair color or bleach would not be able to change the color of the hair.
There are different types of oxidizers available, including creams, liquids, and powders. The most common strength of oxidizer used in hair coloring is 20 volume, which is suitable for most hair types and colors. However, for hair that is darker or has been previously colored, a weaker strength, such as 10 volume, may be used. For hair that is lightened to a very light blonde or white, a stronger strength, such as 30 or 40 volume, may be necessary.
In addition to opening the cuticles, hair oxidizers also help to control the amount of lift, or lightening, that occurs during the coloring process. For example, using a 30 volume oxidizer will result in more lift than using a 10 volume oxidizer. The oxidizer will also determine the rate at which the color or bleach develops, with higher volumes resulting in faster development.
It's important to note that using a higher volume oxidizer can cause damage to the hair if not used properly, and it's always recommended to use it under the guidance of a professional stylist. Moreover, it's crucial to follow the instructions on the hair color or bleach package and to use the correct amount of oxidizer.
In conclusion, hair oxidizers are a key component in the hair coloring process, as they open the hair cuticles and allow pigments to penetrate the hair shaft. They also control the amount of lift and the rate of development. They are available in different strengths and types, and it's essential to choose the right one for your hair type and desired result, always under the guidance of a professional stylist.
