Component (G) can be appropriately selected and used depending on the function to be imparted to the hair cleansing composition. In conventional hair cleansing compositions, the transparency of the hair cleansing composition tends to decrease when component (G) is incorporated. In contrast, the hair cleansing composition of the present invention uses a combination of components (A) to (F), and in particular, uses component (B) among N-acyl amino acid surfactants, so even when component (G) is incorporated, the transparency of the hair cleansing composition can be maintained at a high level.

When the content of component (G) is above the lower limit, it becomes easier to impart the function of component (G) to the hair cleansing composition. Furthermore, while the transparency of conventional hair cleansing compositions tends to decrease when component (G) is blended above the lower limit, the hair cleansing composition of the present invention can maintain high transparency even when the content of component (G) is above the lower limit. When the content of component (G) is below the upper limit, the transparency of the hair cleansing composition can be maintained at an even higher level.

Approximately 2g of a commercially available hair cosmetic (hair wax containing candelilla wax, carnauba wax, and microcrystalline wax as the main styling ingredients) was applied to the dried wig to create an evaluation wig.

[0156] The prepared evaluation wig was wet with lukewarm water. Next, 5g of the obtained hair cleansing agent composition was evenly applied to the entire hair of the evaluation wig, and the evaluation wig was massaged to create a lather. The lathering on the hair to which the hair cosmetic had been applied was evaluated according to the following criteria.

[0157] <Evaluation criteria for lathering on hair with hair cosmetic product applied> ○(Good): Lathers up enough to cover the entire hair. × (Poor): The foam does not completely cover the hair, and the hair is visible.

[0158] (Test example 3: Persistence of hair cosmetic residue) After evaluating Test Example 2, the hair cleansing agent composition was thoroughly rinsed off the evaluation wig using lukewarm water, while running fingers through the wig. Next, the evaluation wig was towel-dried and then dried with a hairdryer. The residual feeling of the hair cosmetic was evaluated based on the tactile sensation of the hair of the dried evaluation wig when gripped with the hand, according to the following criteria.

[0159] <Evaluation Criteria for the Residual Sensitivity of Hair Cosmetics> ○ (Good): The evaluation wig before and after application of the hair cosmetic product felt the same, and there was absolutely no feeling of residual hair cosmetic product. × (Poor): The feel of the evaluation wig before applying the hair cosmetic was clearly different from that of the evaluation wig after drying, and it was clear that some of the hair cosmetic remained.
