Hair is very important to humans and its appearance is a sign of health. The treatment of hair and scalp involves the use of shampoos primarily for effective and mild cleansing. Shampoo can be described as a cosmetic preparation, conveniently packaged for use, and is commonly used for cleaning hair, dirt on the scalp, residues from previously used hair styling products, and environmental contaminants.

In recent years, with the acceleration of the pace of life of people, irregular work and rest and high mental stress are caused, and meanwhile, the dandruff removing and itching relieving product has a large market because the health care of the skin of the head, the poor personal hygiene habits and the use of inappropriate hair washing and caring products are not paid much attention to at ordinary times.

The scalp is the part with the most abundant oil secretion of the whole body, keratinocytes on the scalp continuously carry out metabolism activity, once the metabolism is abnormal, a large amount of fungus which takes oil as food, malassezia bacteria, is bred, the balance of the malassezia bacteria on the scalp and the oil secretion of the scalp is damaged, so that a large amount of metabolic waste, namely dandruff is generated, and scalp pruritus is caused.

The therapeutic drugs for dandruff mainly comprise external keratolytic agents such as sulfur, coal tar, salicylic acid and the like, and broad-spectrum antifungal drugs such as ketoconazole, selenium disulfide, zinc pyrithione, piroctone olamine and the like, wherein the clinical use effect of the antifungal drugs is better, and the antifungal drugs are often prepared into shampoo for convenient use. Among these compounds, zinc pyrithione has been classified as a class i substance for dandruff and seborrheic dermatitis by the food and drug administration due to its excellent antifungal effect and ability to slow down the rapid metabolism of epidermal cells.

The invention patent with application number 202010086387.2 discloses an oil-control, dandruff-removal and itching-relieving shampoo and a preparation method thereof, wherein the oil-control, dandruff-removal and itching-relieving shampoo comprises the following components: sodium lauryl sulfate, cocamide MEA, polyquaternium-10, zinc pyrithione, zinc chloride, hydrolyzed rice protein, neoacylglycine, sodium shale oil sulfonate, wherein the zinc chloride is added to the composition formula by the inventor aiming at enabling the zinc pyrithione to be uniformly dispersed in the composition and enhancing the deposition of the zinc pyrithione on the scalp to improve the biological efficiency of the zinc pyrithione to exert the anti-dandruff activity thereof. However, zinc chloride is toxic, can severely stimulate and burn skin and mucous membranes, and can generate certain side effects after long-term use. Therefore, the preparation of the pure natural anti-dandruff and anti-itching shampoo containing zinc pyrithione and having improved dispersibility and solubility is of great significance.
