Background
In the case of a seborrheic scalp, the scalp secretes too much oil and fat, which easily causes bacteria, thereby causing a series of problems such as dandruff, scalp itching, alopecia and the like. About 60 percent of adults in China suffer from problems of excessive scalp grease secretion, excessive scurf and the like to different degrees, wherein the serious condition is about 15 percent, and the proportion of the serious condition is far beyond that of European and American countries. In order to solve the problems, functional additives such as an anti-dandruff agent, a bacteriostatic agent and the like, such as copper zinc pyridinium sulfate (ZPT), ketoconazole, climbazole and the like, are added into the shampoo, but the oil-controlling, anti-dandruff and itching-relieving effects of the shampoo are not ideal.
