Which of the following are usually oil and cream and contain conditioning agents?

On-scalp lighteners are formulated specifically to be gentle enough for use on the scalp and often come in oil or cream form. These formulations typically include conditioning agents to help protect and moisturize the hair and scalp during the lightening process. This is particularly important because lightening hair can cause dryness and damage, so the added conditioning agents help mitigate these effects, making the product more user-friendly and suitable for sensitive skin.

In contrast, off-scalp lighteners are generally applied away from the scalp and may have different formulations that do not prioritize scalp comfort. Vivid colors are typically more focused on adding bold pigments rather than conditioning, and toners are used mainly to adjust the tone of the hair after lightening, rather than providing the conditioning benefits associated with on-scalp lighteners. Thus, the distinct qualities of on-scalp lighteners specifically oriented towards scalp safety and hair conditioning establish why they are the correct choice.
