After hair lightening, toner is typically used to create a more natural hair tone. This process helps to neutralize any unwanted brassy or yellow undertones that may appear as a result of lightening. Hair lightening can sometimes leave the hair looking overly bright or unbalanced, and toner allows for adjustments to achieve a desired shade.

Using toner involves applying a semi-permanent dye that can add cool or warm hues back into the hair, enhancing the overall color and providing a more polished finish. This balancing act is essential for achieving a professional-looking result that complements the client's natural coloring, making it an integral aspect of post-lightening care.
