The purpose of using a pre-treatment in chemical services is to protect the hair and enhance the effectiveness of the treatment. Pre-treatments are designed to prepare the hair for subsequent chemical processes, such as coloring or relaxing, by ensuring that the hair's structure is fortified and less prone to damage. They may contain ingredients that help to seal the cuticle, retain moisture, and improve the overall health of the hair before the chemical service is applied. This protective layer can lead to better results as well, as the hair will be more receptive to the chemicals used during the service.

While increasing hair volume, adding fragrance, or speeding up the coloring process may be desired effects of certain products, they do not encapsulate the core purpose of pre-treatments. The main focus is on protection and enhancement, ensuring that the hair remains healthy and capable of undergoing further chemical changes successfully.
