Can hydroxide and thio relaxers be used together during the same hair treatment?

Hydroxide relaxers and thio relaxers serve different purposes and have distinct chemical formulations, making it unsafe to use them together during the same hair treatment. Hydroxide relaxers are strong, alkaline products that work by altering the hair’s protein structure, while thio relaxers function through a different chemical process that generally involves a milder pH.

Using both types of relaxers simultaneously can lead to adverse reactions, including excessive damage to the hair shaft, breakage, and scalp irritation. This is due to the opposing chemical actions of these products; using them together can create unpredictable results and significantly increase the risk of harm to the hair and scalp.

It's essential to adhere to the guidelines that emphasize not mixing different types of relaxers in a treatment. Doing so ensures the safety and health of the hair and scalp during the chemical processing, which is a fundamental principle in hair care practices.
