Before any chemical service is applied to the hair, it is essential to use a protective barrier product. This product serves as a safeguard for the hair and scalp against possible irritation or damage that can occur during chemical treatments, such as coloring, perming, or relaxing. The barrier helps to ensure that the chemical agents do not directly interact with the skin, which can lead to allergic reactions or chemical burns.

Using a protective barrier also aids in maintaining the integrity of the hair strands by preventing direct contact of harsh chemicals. This is especially crucial for services involving strong formulations that could strip moisture or compromise the cuticle layer of the hair.

While color treatments, deep conditioners, and fragrances might have their own benefits in the overall hair care process, they do not provide the protective function required before chemical services. A protective barrier product is specifically designed for this purpose, making it a necessary step to promote safety and health during chemical processes.
