The goal of performing a patch test is to determine skin sensitivity to products. This test is crucial in identifying allergic reactions or sensitivities that an individual may have to specific ingredients present in cosmetic products such as hair dyes, skin treatments, or other chemical applications used during barbering or cosmetology services.

Assessing skin sensitivity helps professionals avoid adverse reactions in clients, which can range from mild irritation to more severe allergic reactions. By conducting a patch test ahead of service, barbers can ensure the safety and comfort of their clients, leading to a more positive experience overall.

While checking for hair loss, ensuring color matches, and testing for split ends are all important aspects of hair and scalp health or aesthetics, these do not pertain to the purpose of a patch test. The patch test specifically focuses on the interaction between the skin and products rather than hair conditions or visual conformity.
