Abstract
A shampoo composition is disclosed. The composition comprises an amidoamine-type amphoteric surface active agent, a specific type of modified silicone polymeric compound, and a specific type of polymer. It gives an excellent soft and smooth feeling during washing and rinsing, a superb natural hair-set effect without oily stickiness and roughness, and easy passage of comb through the hair. It is also mild to the skin, the mucous of the eyes, and the like.
