What does the term "intensity" refer to in haircoloring?

In the context of haircoloring, "intensity" refers specifically to the strength of the color's appearance. This term describes how vibrant or full-bodied the color looks after application. Intensity can vary among different shades and formulations, with some colors appearing more vivid and striking, while others may appear more subtle and muted.

Understanding intensity is crucial for colorists as they select the right shades to achieve the desired look for their clients. A color with high intensity would be prominently noticeable and might be used to create bold styles or trends, while lower intensity colors are often preferred for more natural or understated looks.

The other concepts mentioned, such as the depth of color application, chemical stability, and duration of the color's effect, refer to different characteristics of haircoloring but do not pertain to the strength or visual impact of the color itself.
