PROBLEM TO BE SOLVED: To provide a shampoo preparing the hair and the scalp in a flexible state and in the healthy state in the shampooing of the hair and the scalp by strongly cleaning oxidized sebum and protein stain by the characteristics as a weak alkaline agent at the start of the shampooing, heightening the affinity of the hair and the scalp by changing the acidity to weak acid with time at the latter half, and further allowing proteins to be adsorbed by increasing the subcutaneous blood flow by the percutaneous absorption into the scalp of carbon dioxide gas generated by a neutralization reaction.SOLUTION: The hair and scalp-shampooing agent is obtained by preparing an agent-A and an agent-B, containing a surfactant as a main component, mixing sodium bicarbonate of 3-15 wt.% with the agent-A when used, and previously mixing an organic acid such as citric acid of 5.8-20 wt.% with the agent-B. When using the agent, the separately packaged sodium bicarbonate is mixed with the agent-A just before the use, the agent-A and the agent-B are taken on the hand, and the shampooing is carried out. As a result, the acidity is changed from the weak alkali to the weak acid with time, and in addition, the subcutaneous blood flow is promoted by the carbon dioxide gas to impart moisture, gloss and flexibility to the hair, and to improve the health of the scalp. |
