Description

Technical Field

[0001] The present invention relates to the field of personal care, and specifically to a herbal extract anti-dandruff and oil-control shampoo and its preparation method. Background Art

[0002] With the acceleration of the modern life rhythm, more and more people are facing problems such as oily scalp, increased dandruff, and frizzy hair. Oily scalp is one of the common troubles faced by many consumers. Especially in a hot and humid environment, the scalp producing too much oil can easily make the hair sticky, causing inconvenience in daily life. At the same time, the dandruff problem also plagues a large number of consumers. Especially when the scalp secretes too much oil, dandruff often occurs along with it.

[0003] There are a wide variety of shampoo products on the market. However, although most oil-control shampoos can effectively remove oil, they may bring side effects such as dry and frizzy hair. And although the dandruff-control shampoos on the market can effectively remove dandruff, they usually do not have the oil-control effect. Moreover, using shampoo products with more chemical components for a long time may cause an additional burden on the scalp. For consumers with oily scalps and prone to dandruff, how to find a shampoo that can both control oil and remove dandruff while protecting the health of the scalp has become an urgent problem to be solved.

[0004] In addition, modern consumers are paying more and more attention to chemical components. Many people are beginning to prefer hair care products with natural plant ingredients, hoping to achieve the ideal hair care effect while avoiding the side effects brought by chemical additives. Herbal extract components are gradually favored by consumers due to their naturalness, safety, and multiple effects. Applying herbal plant extracts to shampoo products can not only effectively condition the scalp but also achieve multiple effects such as oil control, dandruff removal, and scalp nourishment through the natural active ingredients of the plants.

[0005] Therefore, developing a natural shampoo product mainly composed of herbal plant extracts and having the effects of oil control and dandruff removal to meet consumers' needs for healthy, natural, and efficient hair care has become an urgent issue to be solved. Summary of the Invention

[0006] In view of this, in order to overcome the deficiencies in the prior art, the purpose of the present invention is to provide a herbal extract anti-dandruff and oil-control shampoo and its preparation method. By effectively proportioning natural herbal plant extracts and oil-control and anti-dandruff ingredients, it can not only control oil and remove dandruff, but also moisturize the scalp, providing a shampoo product suitable for people with oily scalps and prone to dandruff. This herbal extract anti-dandruff and oil-control shampoo contains a variety of natural herbal plant extracts and surface active ingredients, and through precise ingredient proportioning, it ensures that while achieving the effects of oil control and dandruff removal, it can gently care for the scalp and avoid the burden on the scalp caused by chemical components. Specifically, the shampoo of the present invention contains cleaning ingredients such as sodium lauryl polyether sulfate, which can effectively remove the oil on the scalp and hair. At the same time, plant extracts such as tea tree, camellia, and sapindus mukorossi added to the formula have the effects of oil control, dandruff removal, soothing, and anti-inflammation, and can maintain the healthy state of the scalp. The mild formula of the present invention avoids the use of a large amount of chemical components and can meet the needs of consumers for natural and safe ingredients. By using a variety of natural plant extracts, the herbal ingredients in the formula not only have the effects of dandruff removal and oil control, but also can improve scalp health, soothe scalp discomfort, reduce allergic and irritation reactions, and are suitable for long-term use.
