The purpose of performing a skin test before chemical treatments is primarily to check for allergic reactions or sensitivities. This step is crucial, as certain chemicals found in hair dyes, relaxers, and other treatments can provoke adverse reactions in some individuals, such as redness, itching, or swelling. By conducting this test, barbers and cosmetologists can gauge how a client's skin reacts to the substance, allowing them to take necessary precautions or select alternative products if needed. Ensuring client safety and comfort is the top priority in any salon practice, which underscores the importance of this preliminary check before proceeding with more intensive chemical applications.

The other options, while relevant to other aspects of hair care and services, do not address the critical concern of health and safety that the skin test aims to fulfill. Matching hair color to preference, assessing hair porosity and texture, and determining the need for a haircut are all important considerations in hair treatments but are not the primary reason for performing a skin test prior to chemical applications.
