In the level system of hair coloring, which number represents the lightest hair color?

In the level system of hair coloring, the scale typically ranges from 1 to 10, with level 1 being the darkest (black) and level 10 representing the lightest blonde. However, some systems extend this range, introducing numbers beyond 10, where 12 would represent an even lighter shade.

In this context, the number that represents the lightest hair color is indeed 10, since it is at the top of the traditional industry standard scale, where further increments like 11 or 12 would often indicate trends or specialized products but are less commonly used. This choice of 10 indicates the highest level of lightness in conventional hair coloring terms, representing the maximum lift that can be achieved with typical hair color products, particularly in common salon practices.

The clarity of this system is crucial for barbers and stylists, as it assists in achieving desired tones while also ensuring that clients receive accurate color results based on their natural hair level.
