The invention discloses tea 
saponin shampoo and a preparation method thereof. The 
shampoo takes a natural surfactant tea 
saponin as a main surfactant, and the tea 
saponin has good emulsifying, dispersing, 
wetting and foaming capacities, and has physiological activities of removing 
dandruff, resisting 
bacteria, relieving 
itching and the like. A 
micelle co-
dissolution technology is adopted, a micromolecular amphiphilic surfactant is compounded to serve as a 
micelle inducer, macromolecular micelles are converted into micromolecular micelles, and the defects that the surfactant is prone to remaining and not easy to wash are overcome; and on the basis of the physiological activities of the tea saponin, 
camellia oil, a rosemary extracting solution, a cacumen biotae extracting solution, a 
white willow bark extracting solution, a chamomile extracting solution, a gentian extracting solution, a 
witch hazel extracting solution, octacosanol, 
squalene and other naturally extracted effective functional components are added to prepare the 
shampoo which is green and natural, has the effects of killing 
bacteria, relieving 
itching and removing 
dandruff, and has excellent conditioning performance onhair and 
scalp.
