The duration for which violet-toned shampoo remains on hair significantly influences the product’s effect on brassiness. This product utilizes violet pigment to neutralize unwanted yellow or orange tones in blonde, silver, or highlighted hair. A typical application may range from a few minutes for subtle toning to a longer period for more intense correction, depending on the product’s strength and desired outcome.
Proper application timing is crucial to achieving the intended result. Insufficient contact may not effectively counteract brassy tones, while excessive contact can lead to an undesirable purple tint, particularly in lighter hair shades. The development of such products represents a response to the evolving hair coloring trends and a desire to maintain a specific aesthetic after bleaching or highlighting. The method provides a non-permanent color correction solution.
