Science

Mechanism of Action

Thiolactic Acid's mechanism of action centers on its reactive sulfhydryl (-SH) group, which facilitates its role as a reducing agent by donating hydrogen or removing oxygen from other compounds. This reducing capacity extends to its antioxidant activity, where it inhibits oxygen-driven reactions to preserve ingredient stability. In specific applications, it functions by disrupting the structural integrity of hair fibers.
