Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a plant extract composition with a scalp care effect and a preparation method and application thereof. Background technique [0002] As one of the thinnest parts of human skin, the scalp, coupled with the high-density distribution of skin appendages such as pilosebaceous glands, makes it easy for external stimuli such as ultraviolet (UV) and pollutants (PM2.5) to penetrate into the scalp, causing damage to the scalp structure. Damage, resulting in a weaker barrier function of the scalp than that of the trunk skin. At the same time, the scalp is one of the three major oil-producing areas of the human body. The sebum secreted in large quantities can be utilized by microorganisms such as Malassezia, resulting in a large number of microorganisms; while the peroxides produced by old sebum under the action of UV, such as horny peroxide Squalene, malondialdehyde, etc. will further st...
