Arizona Cosmetology Practice Exam

What should you check to determine if a hair product is still safe to use?

1. The brand of the product

2. Changes in color, smell, consistency, and the expiration date

3. The price of the product

4. The texture of the container

The correct answer is: Changes in color, smell, consistency, and the expiration date

To determine if a hair product is still safe to use, it is essential to check for changes in color, smell, consistency, and the expiration date. These factors can indicate whether the product has degraded over time or has become contaminated. Changes in color or smell can signal that the ingredients may have broken down or reacted with each other, potentially making the product ineffective or unsafe. The consistency of the product can also provide clues; for instance, if a liquid has separated or if a cream has become too thick or watery, it may no longer be suitable for use. Additionally, the expiration date is a critical marker for safety, as products can have a shelf life beyond which their effectiveness diminishes or risks to safety increase. Looking at brand reputation, pricing, or the texture of the container does not directly inform you about the safety or efficacy of the product itself. Therefore, monitoring the physical characteristics and expiration date of the product is the most reliable way to ensure it remains safe to use.
