Human　hair　waste　(HHW),　used　primarily　for　wigs,　saw　its　global　trade　value　rise　from　$6.36　million　in　1991　to　$149.4　million　in　2020.　This　study　maps　the　global　HHW　trade　network　from　1991　to　2020,　analyzing　its　structural　evolution　using　the　temporal　exponential　random　graph　model　(TERGM).　The　network　reveals　hub　nodes　acting　as　bridges,　with　Southeast　Asia,　particularly　India　and　China,　as　key　players　in　exports　and　imports　respectively.　Factors　like　fashion　trends,　religious　culture,　and　linguistic　and　geographic　elements　influence　trade　network　formation.　Countries　with　pronounced　fashion　inclinations　and　religious　disparities　exhibit　stronger　trade　cooperation.　This　study　offers　insights　for　businesses　to　navigate　HHW　markets　and　emphasizes　the　importance　of　this　resource　for　a　stable　global　supply　chain,　promoting　a　shift　towards　a　circular　development　model.
