Alaska Hairdresser and Barber Certification Practice Exam

Define 'skin sensitivity test'.

1. A test done to analyze hair texture

2. A procedure to check for split ends

3. A test performed on the skin to check for allergic reactions to products

4. A method for testing hair porosity

The correct answer is: A test performed on the skin to check for allergic reactions to products

The definition of 'skin sensitivity test' pertains to a procedure that evaluates how the skin reacts to certain products, particularly those that contain chemicals or allergens. This test is essential because it helps to identify potential allergic reactions before applying hairdressing or cosmetic products, thereby ensuring the safety and comfort of clients. Performing a skin sensitivity test minimizes the risk of adverse reactions which can lead to irritation, hives, or other allergic responses, making it a crucial practice in the beauty and haircare industry. Other choices do not pertain to this specific function; they focus on hair texture, split ends, and hair porosity, which are unrelated to skin reactions or testing.
