What does Undertone refer to in haircoloring?

Undertone in haircoloring refers specifically to the warm or cool tone that exists within the predominant haircolor. It helps to define the overall shade of the hair. For instance, a person's hair might appear as a medium brown, but its undertone could be warm (with hints of gold and red) or cool (with ash or blue tones). Understanding undertones is crucial for achieving the desired haircolor, especially when formulating hair dyes and deciding on color corrections or enhancements. This knowledge allows stylists to create a more personalized and flattering result for their clients, ensuring that the overall look harmonizes with their skin tone and personal style. Hence, the correct understanding of undertones plays a pivotal role in the art of haircoloring.
