The most effective technique for preventing scalp burns during a relaxer application is the application of a protective barrier cream. This cream forms a physical barrier between the scalp and the caustic chemicals found in relaxers, significantly reducing the risk of irritation or burns that could occur if the product comes into direct contact with the sensitive skin of the scalp. The barrier cream acts as a shield, allowing for the relaxer to be applied safely to the hair without compromising the scalp's integrity. While applying a moisturizer can help hydrate the scalp, it does not provide the same level of protection against the chemicals in a relaxer. Using a comb is primarily for sectioning and distributing the product evenly, and it does not address the risk of chemical burns to the scalp. Similarly, wearing gloves is essential for protecting the cosmetologist's hands but does not protect the client's scalp from potential burns. Therefore, the most effective method for preventing scalp damage during a relaxer application is indeed the use of a protective barrier cream.
