When can a client's hair properly accept a permanent toner?

Before it is cut
After it has been washed
After it has been lightened
When it is still damp

The correct answer is: After it has been lightened

A client's hair can properly accept a permanent toner after it has been lightened because the lightening process opens the cuticle of the hair. This allows the toner to penetrate more effectively and achieve the desired color result. When hair is lightened, the underlying pigments are exposed, and toners can neutralize unwanted tones, such as brassiness or dullness, bringing the hair to the desired shade. Understanding the timing of applying toner is crucial. If applied to unlightened hair, the toner may not achieve the intended results, as there wouldn't be a base color for the toner to adjust. Therefore, the hair must first be lightened to the right level to ensure that the toner can effectively alter the color, making it more vibrant or neutral as required.
