What is the purpose of a patch test prior to a chemical treatment?

The purpose of a patch test prior to a chemical treatment is to determine if there is any allergic reaction to the product. This is essential for ensuring the safety of the client, as some individuals may have sensitivities or allergies to specific ingredients in hair or skin care products. Conducting a patch test helps identify potential allergic reactions before the full application of the product, which could otherwise lead to adverse effects such as redness, swelling, or more severe allergic responses.

Understanding why this procedure is critical for safety in the salon highlights the importance of client care and adherence to safety protocols in the cosmetology field. Properly assessing a client's sensitivity to products is a key step in providing effective and safe beauty treatments.
