Before performing a chemical service, conducting a patch test for allergies is essential to ensure the safety and well-being of the client. This process involves applying a small amount of the chemical product to a discreet area of the skin to check for any adverse reactions, such as redness, itching, or swelling, which could indicate an allergy to the product. Identifying potential allergies beforehand helps in preventing severe reactions during or after the chemical service, ultimately safeguarding both the client and the stylist.

While providing a detailed consultation and discussing the client’s hair and skin type is crucial, it does not specifically address the immediate risks associated with chemical services. Deep conditioning treatments and scalp massages may be beneficial for hair health or relaxation but do not serve as a precautionary measure against allergic reactions. Therefore, conducting a patch test stands out as a vital step before any chemical application to prioritize client safety.
