Abstract

The present invention is about composition for preventing hair loss or promoting hair growth comprising indirubin derivatives; and one or more selected from the group consisting of Euodia daniellii extract, Persicaria hydropiper extract, Hovenia dulcis extract, methyl vanillate, hesperidin and quercitrin; as an active ingredient. In addition, one or more selected from the group consisting of Euodia daniellii extract, Persicaria hydropiper extract, Hovenia dulcis extract, methyl vanillate, hesperidin and quercitrin of the present invention is a natural-derived composition with little toxicity to cells. Indirubin derivatives are stable compounds that have been found to have little toxicity to the human body, and therefore, when used in a mixture thereof, there are advantages in that they do not exhibit adverse effects on the human body, unlike conventional steroid drugs.
