What is the purpose of the level system in haircoloring?

The purpose of the level system in haircoloring is primarily to determine the lightness or darkness of a color. This system categorizes hair colors on a scale, typically ranging from 1 to 10, where 1 represents the darkest shade (black) and 10 represents the lightest shade (light blonde). By using this level system, hair colorists can effectively communicate and select hair colors that meet the desired aesthetic effects and match the natural hair's undertones. It is a critical tool in achieving the right shade, allowing professionals to blend and formulate colors accurately, ensuring that clients achieve their desired outcome. This systematic approach provides clarity and consistency in the color application process.
