Fermented Yeast Complex Extract Promotes Hair Regrowth by Decreasing Oxidative Stress.

ABSTRACT: Hair growth is orchestrated by a complex cycle comprising the anagen, catagen, telogen, and exogen phases that are largely regulated by dermal papilla cells (DPCs). The disruption of oxidative balance and inflammation impairs follicle function and regeneration. Fermented yeast complex extract (FYCE) is a bioactive material derived from enzymatically hydrolyzed yeast and collagen substrates through a two-step fermentation with Lactobacillus brevis and Lactobacillus plantarum, enriched in antioxidant amino acids such as γ-aminobutyric acid (GABA) and L-alanine. In this study, we evaluated the effect of FYCE on hair regrowth, with a focus on its modulation of oxidative stress and inflammatory pathways in hydrogen peroxide (H₂O₂)-treated DPCs. FYCE treatment
