         8 . The shampoo composition of  claim 1 , wherein the log P value of the one or more chelants is from about −3 to about 0. 
     
     
         9 . The shampoo composition of  claim 1 , wherein the molecular weight of the one or more chelants is from about 75 to about 400. 
     
     
         10 . The shampoo composition of  claim 1 , wherein the molecular weight of the one or more chelants is from about 100 to about 350. 
     
     
         11 . The shampoo composition of  claim 1 , wherein the molecular weight of the one or more chelants is from about 125 to about 325. 
     
     
         12 . The shampoo composition of  claim 1 , wherein the molecular weight of the one or more chelants is from about 140 to about 300. 
     
     
         13 . The shampoo composition of  claim 1 , further comprising a gel network, wherein the gel network comprises a fatty alcohol and a surfactant. 
     
     
         14 . The shampoo composition of  claim 1 , wherein the shampoo composition comprises from about 0.01% to about 3% of the one or more chelants. 
     
     
         15 . The shampoo composition of  claim 1 , wherein the shampoo composition comprises from about 0.01% to about 1% of the one or more chelants.
