Glossary Antioxidant Defenses

Antioxidant defenses refer to the body's mechanisms that protect cells from oxidative stress caused by free radicals, which can damage DNA, proteins, and lipids. In the context of hair loss, oxidative stress has been linked to conditions such as androgenetic alopecia and telogen effluvium, where an imbalance between free radicals and antioxidants can lead to hair follicle damage and impaired hair growth. Key distinguishing characteristics of antioxidant defenses include the presence of enzymes like superoxide dismutase and catalase, as well as non-enzymatic antioxidants such as vitamins C and E, which work together to neutralize harmful oxidative agents. Maintaining robust antioxidant defenses is crucial for promoting healthy hair follicles and potentially mitigating hair loss.
