    TLDR Salmon nasal cartilage proteoglycan may help hair grow.
    The study investigated the effects of salmon nasal cartilage proteoglycan (PG) on hair growth, finding that daily oral ingestion of PG enhanced hair growth in mice. The mechanism involves PG stimulating vesicular endothelial growth factor production in human follicle dermal papilla cells via insulin growth factor-1 receptor signaling. This suggests that PG ingestion could potentially improve hair loss.
