What type of hair should not be treated with chemical relaxers?

Chemical relaxers are specifically designed to alter the shape of the hair by breaking down its natural bonds, allowing it to be straighter and more manageable. However, certain hair types can be more susceptible to damage when treated with these relaxers. Ethnic hair, often characterized by its density and curl pattern, can be particularly vulnerable to over-processing.

When chemical relaxers are applied to ethnic hair, it may lead to severe dryness, breakage, and an overall unhealthy appearance if not done correctly. This type of hair typically requires gentle handling and specialized products that cater to its unique structure to maintain its health and integrity. Therefore, while straight, fine, and thick hair can generally withstand chemical treatments with proper technique and formulations, ethnic hair often thrives on moisturizing and nourishing treatments rather than strong chemical alterations like relaxers.
