The duration for which a color-correcting hair product is applied significantly affects the final shade and overall health of the hair. Application time is a crucial factor in achieving the desired tonal effect. For instance, if a brassy blonde wishes to achieve a cooler, ashier tone, the application time influences the degree to which the yellow tones are neutralized.
Appropriate processing time is essential to ensure the hair’s health and the product’s efficacy. Leaving a toner on for the correct duration prevents over-processing, which can lead to damage, dryness, and breakage. Moreover, understanding the timing contributes to consistent, predictable results, reducing the risk of undesirable or uneven color.
