What is the process of applying a deposit-only color over previously highlighted hair called?

The process of applying a deposit-only color over previously highlighted hair is known as "fur light." This technique involves using a color formula that adds pigment without lifting the existing color, making it ideal for emphasizing the highlights while still providing uniformity and depth to the hair. It is particularly useful for enhancing the richness of color in highlighted hair, allowing the stylist to create a more vibrant and cohesive look without altering the lightness of the previously highlighted sections.

The name "fur light" signifies the gentle nature of the process, as it does not strip the hair of its previous color but rather enhances and blends with it. This technique can also be beneficial for toning down over-processed or brassy highlights, making it a valuable skill for a certified hair colorist.

In this context, "gray reduction" refers to the process of covering gray hair rather than enhancing highlights. "Grazing" is a term not commonly associated with hair color techniques, and "collage" generally refers to a style of coloring that combines various techniques, not specifically to applying a deposit-only color over highlighted hair.
