    TLDR Balding scalps show different gene expressions affecting hair growth compared to non-balding scalps.
    The SnapshotDx Quiz from the Journal of Investigative Dermatology in August 2016 focused on androgenetic alopecia (AGA), highlighting its genetic and hormonal influences, particularly dihydrotestosterone (DHT). The study by Chew et al. found that androgen receptors (AR) and TWIST1 expression were upregulated in balding scalps, while vasculature-related genes were down-regulated in balding dermal papilla cells, affecting hair follicle cycling and growth. The document also discussed the expression of VCAN (versican) protein and spermidine synthase, noting that both were highly expressed in balding and non-balding scalps. Versican was crucial for hair morphogenesis, while spermidine synthase promoted hair growth by stimulating hair shaft elongation and prolonging the anagen phase. These findings highlighted the molecular differences in balding versus non-balding scalps and their potential roles in hair growth and loss.
