What must be applied to a client’s hair before using chemical treatments for extensions?

Before applying chemical treatments for extensions, it is essential to use a protective product. This type of product is specifically designed to create a barrier that helps shield the hair from the potentially damaging effects of chemicals involved in processes like coloring, perming, or bonding. The protective product may contain ingredients that help to maintain moisture, strengthen hair, and minimize damage during the chemical application, ensuring that the client's natural hair remains healthy after the treatment.

Using a leave-in conditioner, styling gel, or volumizing spray does not provide the same level of protection against the specific risks associated with chemical treatments. While these products can be beneficial for styling or maintaining moisture, they do not serve the primary purpose of protecting the hair structure during chemical exposure. The protective product is crucial for promoting the health and integrity of both the natural hair and the extensions post-treatment.
