When should a patch test be performed?

• A. 24 to 48 Hours Before a Color Service
• B. Before Any Service
• C. During a Color Service
• D. A Week Before Service

Answer: (B)

Patch testing is a safety check to detect possible allergies to ingredients in hair products before any service. It’s done before any service so you don’t run the risk of exposing a client to a product they might react to, whether that service involves color, chemical processing, or even routine topical products. By testing first, you can prevent adverse reactions, keep the client safe, and choose a product they can tolerate. In practice, you apply a small amount of product on the skin (commonly behind the ear or on the inner forearm) and wait about 24 to 48 hours to watch for signs like redness, itching, or swelling. If a reaction occurs, you avoid that product and select alternatives; if there’s no response, you can proceed with the service. This approach aligns with salon safety policies that prioritize client well-being before applying any product.
