Description

Technical Field

[0001] The present invention relates to the technical field related to toiletries, and in particular to a low-irritation anti-hair loss cleansing shampoo and a preparation method thereof. Background Art

[0002] In today's society, with the increasing pressure of life, the aggravation of environmental pollution and the influence of bad living habits, hair loss has become a common problem that troubles many people. According to relevant survey data, the number of people with hair loss in the world is increasing every year. In order to meet consumers' demand for anti-hair loss shampoo, a large number of related products have emerged on the market. Existing anti-hair loss shampoos mainly have the following problems: First, some products rely on chemically synthesized anti-hair loss ingredients, such as minoxidil. Although they have an anti-hair loss effect to a certain extent, these ingredients are highly irritating and can easily cause allergic reactions such as itching, redness and swelling of the scalp. Long-term use may also damage the scalp's microecological environment and lead to an imbalance in the scalp's oil secretion; second, in terms of the selection of cleansing ingredients, most products use sulfate surfactants, such as sodium lauryl sulfate. Although these surfactants have strong cleaning power, they will excessively remove the natural oils of the scalp and hair, damage the scalp barrier, make the scalp dry and sensitive, and further aggravate the hair loss problem; third, the existing preparation process is usually a simple mixing and stirring process, which cannot fully exert the synergistic effect between the various ingredients, resulting in unstable anti-hair loss and cleansing effects of the product, making it difficult to achieve the ideal use effect.
