Anti-dandruff agents are designed to reduce the formation of dandruff flakes. The cause of dandruff is not fully understood, but treatment involves the use of multiple "active ingredients" that act as both antibacterial and antimitotic agents. Two of the more popular ingredients are currently zinc pyrithione and selenium sulfide. The other approved "actives" are salicylic acid, sulfur and coal tar solutions.
Strong antifungal action, but poor anti-pseudomonas activity, so shampoos containing ZPT require the addition of a preservative. It reacts with chelating agents (with zinc), oxidants, UV and visible light.
Selenium Sulfide effectively inhibits the growth of M. ovalis, one of the main culprits of dandruff, and is often used to thoroughly exfoliate the scalp and stop itching.
Ketoconazole has strong bactericidal ability when applied topically, so it is effective in treating dandruff caused by Malassezia as well as itching and inflammation of the scalp caused by other fungi.
The raw materials of the natural plant anti-dandruff ingredients are extracted, purified and compounded from natural plants such as Scutellaria baicalensis, Radix Scutellariae Sinensis, Phyllostachys, Dandelion, Cyperus rotundus and Bitter Ginseng. The main effect of these plant extracts is to inhibit and kill Malassezia, which is the main cause of dandruff, and they have the ability to kill bacteria.
There are three main factors that cause dandruff: Malassezia, sebum, and individual susceptibility.
Dandruff is the premature shedding of abnormal keratinized skin cells. Scalp oil secretion and individual susceptibility are inherent, not easy to change; Therefore, the vast majority of anti-dandruff ideas are based on the use of antifungal ingredients to inhibit Malassezia.
