The invention provides a nutrient solution for eyelashes. The nutrient solution for eyelashes comprises, by weight, 0.3 to 4 parts of fleece-flower root extract, 0.2 to 2 parts of the extract of Eclipta prostrata and 1 to 8 parts of melanin from black sesame. The nutrient solution for eyelashes can effectively promote blood circulation at the roots of the eyelashes and improve nutrient input into hair roots of the eyelashes, so the growth of the eyelashes is promoted, and the eyelashes have enhanced resistance to external damage, become firmer and not prone to falling; and thus, the eyelashes are allowed to become more dense.
