Final answer:
The client record usually includes information like processing time, color formulation, and contact information, but not legal information, which is less relevant for service delivery.
Step-by-step explanation:
In a business setting, particularly in a service industry like hairdressing, the client record typically includes a variety of information to facilitate ongoing service delivery. However, among the options provided, legal information is the least likely to be included in a client record. The client record would typically house details such as processing time for services rendered, color formulation in the context of hair coloring, and contact information to reach out to the client for future appointments or follow-ups. Legal information does not typically relate to the direct services provided and thus, would usually not be part of a client record in this context unless there is a specific requirement for it.
