Hair growth promoting effect of essence manufactured with products fermented by Lactobacillus rhamnosus and Backryeoncho (Opuntia ficus-indica var. sarboten) fruits in mice

In the 2012 study, researchers found that an essence made from products fermented by Lactobacillus rhamnosus and backryeoncho fruits promoted hair growth in male C57BL/6 mice more effectively than minoxidil. The essence was applied topically at 0.1 mL daily for 8 days, resulting in significant hair growth without adverse effects on body weight or food intake. Histological analysis showed that the essence increased the depth and size of hair follicles more than minoxidil. The study concluded that the fermented product essence has a potent hair growth promoting effect, warranting further research for practical use.
