Liquid hair dye composition

A hair dyeing method, comprising the following (I) and (II):

• (I):
• mixing a first agent comprising an alkali agent and an oxidative dye precursor, a second agent comprising an oxidizing agent, and a liquid hair dye composition as a third agent comprising the following components (A), (B) and (C):
• (A) one or more azo dyes selected from the group consisting of the following formulae (A-1), (A-2) and (A-3), in a content of 1.5 mass % or more:
• (B) one or more surfactants with an HLB of 7 or more, selected from the group consisting of an anionic surfactant, an amphoteric surfactant, and a polyoxyethylene alkyl or alkenyl ether having an alkyl or alkenyl group with from 12 to 20 carbon atoms, having a polyoxyethylene with an average number of added moles of from 20 to 60;
• and
• (C) water;
• in a mass ratio of the third agent to a total of the first agent and the second agent, (the third agent/(the first agent+the second agent), of 0.01 or more and 0.4 or less, to prepare a liquid mixture;
• and
• (II):
• applying the liquid mixture prepared in (I) to hair,
• wherein said liquid mixture does not contain 2-amino-2-methylpropanol.
