Description

Technical Field

[0001] The present invention relates to the technical field of cosmetics, and in particular to a composition for alleviating scalp aging, a preparation process and an application thereof. Background Art

[0002] Hair is a natural high-molecular keratin fiber that covers the scalp. It prevents the scalp from dissipating heat, protects the scalp from damage, and makes it more beautiful. Bright and healthy hair and beautiful hairstyles can bring unique charm to people. Hair keratin fibers are not active, but light, hot hair, acids, alkalis, oxidants, and reducing agents can damage hair. Among the many factors that cause hair damage, ultraviolet rays are an important factor that causes hair damage and are also the only controllable factor. Among them, UV-B radiation mainly affects the melanin and keratin of hair, which will cause the disulfide bonds of keratin in the hair fiber and on the surface of the hair to break; UV-A will produce free radical reactive oxygen species (ROS) through the interaction between endogenous photosensitizers. Hair damage caused by ultraviolet radiation is called photoaging damage, which is manifested in appearance as frizzy, yellow, broken and split ends, and dullness.

[0003] The mechanism by which sunscreen protects hair is that it absorbs ultraviolet rays within a certain wavelength range and converts the light energy into heat energy or harmless visible light. The ultraviolet rays cannot come into contact with the photosensitive substances in the hair to cause photooxidation, thereby protecting the internal structure of the hair. Most of the sunscreens added to hair care products come from the anti-ultraviolet raw materials in skin care products.

[0004] Currently, the shampoo and conditioner products containing anti-aging compositions have certain anti-aging effects, but the anti-aging effects are poor and cannot effectively improve hair loss and promote hair growth. Therefore, it is necessary to develop a composition for alleviating scalp aging. Summary of the invention

[0005] The present invention provides a composition for alleviating scalp aging, a preparation process and an application thereof, so as to solve the problem that the washing and care products in the prior art cannot effectively alleviate scalp aging, and the prepared composition can improve the free radical scavenging performance, reduce the level of ultraviolet-induced inflammation, and alleviate the reduction of scalp elasticity after light exposure. Long-term use can effectively improve and repair hair light damage and photooxidation, and alleviate scalp aging.
