Zusammenfassung:1 2 3 2 Provided is a hair-treatment composition containing: a first amphoteric surfactant having a structure represented by general formula (1) below; at least one type of second amphoteric surfactant selected from the group consisting of fatty acid amide propyldimethylaminoacetic acid betaines, alkyldimethylaminoacetic acid betaines, N-acylaminoethyl-N-2-hydroxyethylaminocarboxylic acid salts and N-acylaminoethyl-N-carboxymethoxyethylaminocarboxylic acid salts fatty acid amide propyldimethylaminoacetic acid betaines, alkyldimethylaminoacetic acid betaines; and an acidic amino acid. In general formula (1), Rrepresents an alkyl group the carbon number of which is 6 to 20; Rrepresents a methyl group, an ethyl group, or a hydroxyethyl group; Rrepresents a methyl group, an ethyl group, or a -CHCOOH group; and n is an integer from 1 to 3.
