         3 . The method of  claim 1 , wherein the conditioner composition comprises from about 0.1% to about 0.15% histidine, by weight of the conditioner composition. 
     
     
         4 . The method of  claim 1 , wherein the conditioner composition further comprises one or more additional benefit agents. 
     
     
         5 . The method of  claim 4 , wherein the one or more additional benefit agents is selected from the group consisting of anti-dandruff agents, vitamins, chelants, perfumes, brighteners, enzymes, sensates, attractants, anti-bacterial agents, dyes, pigments, bleaches, and mixtures thereof. 
     
     
         6 . The method of  claim 4 , wherein the one or more additional benefit agents is an anti-dandruff agent. 
     
     
         7 . The method of  claim 1 , wherein the shampoo composition has a pH of from about 3.5 to about 5.
