Prelightening the hair is usually necessary when using a:

Toner
Semi-permanent dye
Direct dye
Natural dye

The correct answer is: Toner

Prelightening the hair is typically required when using a toner as the hair needs to be lightened enough to be able to pick up the desired tonal shade from the toner. This is not necessary when using a semi-permanent dye, as it does not contain a developer and can only deposit color on top of your natural hue. Direct dyes also do not require prelightening as they are deposit-only dyes that fade gradually over time. Natural dyes, such as henna, also do not require prelightening as they do not contain harsh chemicals that can lighten the hair. Therefore, prelightening is usually only necessary when using a toner to achieve the desired result.
