What factor is essential in determining the correct toning color for blonde hair?

Determining the correct toning color for blonde hair heavily relies on understanding the underlying pigment present in the blonde hair. Hair bleach strips the hair of its natural color, revealing the underlying pigments that can greatly influence the final tone of the hair. For instance, if the underlying pigment is yellow, adding a violet toner can help neutralize that yellow, leading to a more balanced and desired blonde shade. Similarly, if the underlying pigment has warmer hues, the toner selection will differ to achieve the appropriate adjustment.

While factors like client preference, the current length of the hair, or seasonal trends can influence decisions in hair color treatments, they do not provide the necessary foundation for selecting the correct toning color. Without addressing the underlying pigment, the outcome may not align with the client's expectations or hair goals, making an understanding of that pigment vital in achieving the desired result.
