Using a barrier cream before applying chemical treatments is essential for protecting the skin from potential irritation or chemical burns caused by the products. These treatments can be harsh, and the barrier cream acts as a shield that prevents direct contact between the chemicals and the skin. This is particularly important in areas where chemicals may drip or splatter during the application process, such as along the hairline or on the ears.

The other options, while they have their uses, do not provide the same level of protection. A towel may absorb some of the product or protect clothing but does not shield the skin itself. Plastic gloves are crucial for protecting the hands of the stylist but do not offer protection for the client’s skin. Hair spray has no protective function against chemical treatments. Therefore, barrier cream is the best choice for ensuring both the safety of the client and the effectiveness of the treatment.
