What is often the first step in a hair service preparation?

The first step in hair service preparation is typically conducting a patch test. This is a critical procedure designed to assess the client's reaction to hair products, particularly those that contain strong chemicals or dyes. Performing a patch test helps identify any potential allergic reactions or sensitivities before applying products to the entire scalp or hair, ensuring the safety of the client.

By prioritizing the patch test, hairstylists can avoid adverse reactions, which could lead to discomfort or even serious health issues for the client. This step is essential for building trust with clients and maintaining a professional standard in hair services. Once it has been established that a client is not allergic to the products being used, other procedures such as shampooing, applying conditioners, or performing massages can follow.
