    TLDR PPAR-γ helps control skin oil glands and inflammation, and its disruption can cause hair loss diseases.
    Peroxisome proliferator-activated receptor γ (PPAR-γ) was identified as a key regulator in lipid homeostasis, sebocyte maturation, and peroxisome biogenesis, with significant anti-inflammatory effects. It was highly expressed in human sebaceous glands, and its disruption was linked to primary cicatricial alopecia (PCA) pathogenesis, particularly causing pilosebaceous dysfunction and follicular inflammation. The review focused on the role of PPAR-γ in the pathogenesis of lichen planopilaris (LPP), the most common lymphocytic form of PCA, and discussed clinical trials that explored the use of PPAR-agonists in treating PCA.
