Anti-Dandruff Claims
In-vitro efficacy testing for anti-dandruff formulations focuses on evaluating their antifungal activity and impact on scalp-associated biomarkers. Key methods include antifungal assays such as minimum inhibitory concentration (MIC) and zone of inhibition tests against Malassezia species, the primary contributor to dandruff. Additionally, biochemical tests assess the formulation’s ability to regulate sebum production and restore scalp barrier integrity. Advanced cell-based assays can evaluate the product’s role in reducing inflammation and oxidative stress, key factors in dandruff pathogenesis. These tests provide robust and reproducible data to substantiate anti-dandruff claims, ensuring scientific reliability and regulatory compliance.

Leukotriene D4 (LTD4) | LTD4 is a potent pro-inflammatory mediator., |
Pro-inflammatory Cytokine Interleukin-1 alpha (IL-1a) | A pro-inflammatory cytokine that plays a key role in the activation of immune responses, promoting inflammation and tissue damage. |
Inflammatory Cytokine Tumor Necrosis Factor alpha (TNFa) | A pro-inflammatory cytokine involved in systemic inflammation, immune system regulation, and the induction of apoptosis in cells. |
Leukotriene D4 (LTD4) | LTD4 is a potent pro-inflammatory mediator., |
Interferon Gamma (IFNg) | IFN-γ is a cytokine involved in the JAK-STAT signaling pathway. It is primarily produced by T cells and natural killer (NK) cells in response to antigenic stimuli. |
