Abstract

The invention belongs to the field of special cosmetics, and particularly relates to a single-agent-type hair colorant. The single-agent-type hair colorant comprises a melanin precursor and is characterized in that the melanin precursor is prepared from, by weight, 70-85% of 5,6-dihydroxyindole, 5-10% of 5,6-dihydroxyindole-2-carboxylic acid, 5-10% of 5,6-dihydroxyindoline and 5-10% of 5,6-dihydroxyindoline-2-carboxylic acid. The obtained single-agent-type hair colorant is high in safety, and the melanin precursor is good in hair coloring effect and high in colorability.

Description

technical field [0001] The invention belongs to the field of special cosmetics, in particular to a safe single-dose hair dye with good hair dyeing property.
