The　main　purpose　of　this　paper　is　to　use　the　laser-induced　breakdown　spectroscopy　(LIBS)　technique　as　a　fast,　noninvasive,　and　low　cost　spectro-biochemical　analysis　laser　spectroscopy　technique.　This　study　will　indicate　the　qualified　performance　of　LIBS　with　the　proposed　optimum　conditions　as　a　promising　and　easy　tool　for　identification,　detection,　and　characterization　of　trace　elements　in　different　hair　types.　The　purpose　of　the　study　is　to　show　that　due　to　the　pollution　of　sites　and　environment　by　heavy　metals　being　a　significant　public　health　risk,　various　diseases　can　be　caused　by　these　elements.　The　present　work　was　conducted　on　various　animal　hair　samples　using　the　LIBS　technique　to　evaluate　the　body　elemental　content　through　a　segment　of　hair.　Qualitative　analysis　was　performed　on　atomic　and　ionic　species　of　elementals　such　as　Cu,　Cd,　Fe,　Pb,　Ni,　Mn,　Co,　and　Zn.　To　determine　the　quantitative　analysis,　the　relative　mass　concentration　was　calculated　as　the　ratio　of　atoms　and　ions　of　the　selected　elements　of　the　reference　element　carbon,　C,　which　is　considered　to　be　a　reference　element　due　to　the　internal　standard　matrix.　These　calculations　provided　the　actual　concentration　of　each　element,　which　can　be　considered　for　further　work.
