The primary purpose of performing a patch test before a color service is to check for possible allergies to products. This is a critical safety step in the process of hair coloring, as some clients may have sensitivities or allergic reactions to certain chemicals found in hair dye. Conducting a patch test, usually on a small area of skin, allows the stylist to observe any adverse reactions that may occur within 24 to 48 hours after application. Ensuring that a client is not allergic to the products used helps prevent serious health issues and promotes the overall safety of the coloring process.

The other options, while related to client consultation and care, do not align with the specific reason for a patch test. Preferences for color or assessments of hair and past treatments are important elements of the overall service but do not directly relate to the health safety measure that a patch test provides.
