Question: 1 / 400

Which product is typically used for a patch test?

Shampoo

Conditioner

Hair dye

The correct choice is hair dye because it contains a variety of potent chemicals that can cause allergic reactions in some individuals. A patch test is performed to determine an individual's sensitivity to certain ingredients in hair dye before applying it to the entire scalp. This is crucial since hair dye is often left on for an extended period, and allergies can lead to serious skin issues.

Shampoo, conditioner, and hair gel are generally less reactive and are typically not associated with severe allergic reactions. While it is still wise to use caution with any hair products, the necessity for a patch test is particularly emphasized for those containing hair dye, due to the higher likelihood of adverse reactions. Safety measures, such as a patch test, help to prevent negative outcomes, ensuring that clients can safely use the product.
