[Technical Problem] When washing hair and scalp, the oxidized sebum and protein stains, which are characteristic of weak alkaline agents, are washed strongly at the start of washing, and in the latter half, weak acidity is changed over time to enhance the affinity of hair and scalp. In addition, carbon dioxide is generated by a neutralization reaction and absorbed into the scalp through the skin, increasing the subcutaneous blood flow, adsorbing proteins, and obtaining a cleaning agent that can condition the hair and scalp in a soft and healthy state. . SOLUTION: A agent and B agent mainly composed of a surfactant are prepared, and 3 to 15% by weight of sodium bicarbonate is mixed in the A agent at the time of use, and 5 acids of organic acids such as citric acid are mixed in the B agent. 8 to 20% by weight is premixed. In use, just before the A agent is mixed with sodium bicarbonate in a separate package, the A and B agents are taken and the hair is washed. As a result, it changes from weak alkalinity to weak acid over time, and in addition, carbon dioxide gas promotes subcutaneous blood flow, moisturizing, suppleness and suppleness to the hair, thereby promoting the health of the scalp.
