1. To avoid allergic reactions

2. To determine hair texture

3. To analyze scalp sensitivity

4. To ensure color fastness

The correct answer is: To avoid allergic reactions

Performing patch tests before chemical services is crucial primarily to avoid allergic reactions. This process involves applying a small amount of the chemical product to a discreet area of the skin, typically behind the ear or on the inner arm, to observe any adverse reactions, such as redness, swelling, or itching. This precaution helps professionals identify clients who may have allergic sensitivities to specific ingredients commonly found in hair dyes, relaxers, or other chemical agents used in cosmetology. Ensuring the safety of clients is paramount in the beauty industry, as allergic reactions can lead to significant discomfort, health issues, or even more severe complications. Therefore, conducting patch tests is a standard practice that safeguards both the client's health and the cosmetologist's professional responsibilities. It stands as a critical step in providing personalized and safe beauty services tailored to individual client needs.
