  Among the above-mentioned acylamino acid type surfactants, palm oil fatty acid-L-glutamic acid, in that the softness of the finish of the hair and the thickness of the finish of the hair (feel that a film is obtained on the hair surface) are good. Lauroylmethylalanine is preferred, and lauroylmethylalanine is preferred in that the finished hair has a particularly excellent thickness.

  The blending amount of the acylamino acid type surfactant in the shampoo composition has a lower limit of 1 mass from the viewpoint of ensuring the softness of the hair finish, the sense of thickness of the hair finish, and the transparency of the appearance of the shampoo composition. % Is preferable, and 5% by mass is more preferable.

  The acylamino acid type surfactant is a kind of anionic surfactant, and the shampoo composition may contain an anionic surfactant other than the acylamino acid type surfactant. If the amount of the anionic surfactant is too large, irritation to the scalp and the hand tends to be strong, so the total amount of the anionic surfactant in the shampoo composition may be 30% by mass or less. Preferably, it is 20% or less by mass.

(B component): Amphoteric surfactant The B component is an amphoteric surfactant, and one or more are used.
By adding the amphoteric surfactant to the shampoo composition, it is possible to improve foaming properties, and it is possible to increase the viscosity of the shampoo composition and improve the handleability.

  Examples of amphoteric surfactants include amidopropyl betaine-type amphoteric surfactants such as coconut oil fatty acid amidopropyl betaine, lauric acid amidopropyl betaine, isostearic acid amidopropyl betaine, linoleic acid amidopropyl, and palm kernel fatty acid amidopropyl betaine.

  Among the above amphoteric surfactants, an amidoalkylbetaine type amphoteric surfactant is more preferable from the viewpoint of improving the softness of the hair finish.

  Furthermore, among the amphoteric surfactants described above, the amidoalkylbetaine amphoteric surfactant and the imidazoline type amphoteric from the viewpoint of not only improving the softness of the finish of the hair but also improving the thickness of the finish of the hair. It is preferable to use a surfactant in combination.

  In addition, although it is an amphoteric surfactant, lauryldimethylaminoacetic acid betaine and lauryl hydroxysulfobetaine are preferably not added to the shampoo composition in that the softness of the finish of the hair cannot be improved.

  If the amount of amphoteric surfactant in the shampoo composition (total amount when using a plurality of amphoteric surfactants) is too small, the effect of improving foaming may be reduced, for example. Therefore, the content is preferably 0.5% by mass or more. The upper limit of the amount of amphoteric surfactant in the shampoo composition is not particularly limited, but is usually about 20% by mass.

(C component): Cationic polymer The C component is a cationic polymer, and one or more of them are used.
By adding the cationic polymer to the shampoo composition, it becomes possible to enhance the conditioning effect of the treated hair, improve the ease of passing through the hair during washing, and reduce squeaking.

  Although not particularly limited, the reason why softness can be imparted to hair treated with a shampoo composition containing component D is considered as follows. That is, hair tends to be damaged more at the tip than at the root portion, and the tip tends to become harder due to the loss of moisture retention power. It is considered that, by softening the tip of the hair that tends to be hardened among the hair to be treated, it greatly contributes to the improvement of the finished softness.

Such polyoxyethylene lanolin and polyoxyethylene shea fat do not contain a polyoxypropylene chain.
The average number of added polyoxyethylenes in polyoxyethylene lanolin and polyoxyethylene shea fat is preferably 30 or more and 60 or less, and 50 or more and 60 or less from the viewpoint of improving stability by improving water solubility. Is more preferable.

  In addition, among the polyoxyethylene lanolin and polyoxyethylene shea fat of component D, it is more preferable to use polyoxyethylene lanolin than polyoxyethylene shea fat from the viewpoint of ensuring the transparency of the appearance of the shampoo composition. preferable.
