Kansas Cosmetology Practice Exam

When should a patch test be performed?

1. Before each hair service

2. Only if the client requests it

3. When using new products on a client

4. It is not necessary

The correct answer is: When using new products on a client

A patch test should be performed when using new products on a client to ensure that the client does not have an allergic reaction to any of the ingredients in the product. This protective measure helps to identify any potential sensitivities beforehand, allowing the professional to adjust their services accordingly and prevent adverse reactions during or after application. Conducting a patch test is particularly important for products that involve strong chemicals, such as hair dyes or certain treatments. This practice enhances client safety and builds trust in the professional's procedures. It's a standard precautionary measure in the cosmetology industry, promoting a responsible approach to client care, especially when new formulations or brands are introduced into the service offerings.
