| 摘要 |
The invention concerns the use of flavylium type compounds, non-substituted in position 3, and substituted by at least a hydroxyl or alcoxy radical, in particular Apigenidin, in pure form or in the form of plant extracts containing them, as colouring agent in or for making compositions for dyeing keratinous fibres, particularly human keratinous fibres such as hair. The invention also concerns the dyeing compositions containing them, particularly cosmetic compositions for direct hair dyeing, and the corresponding dyeing method. The hair dyes resulting from the use of these colouring agents are particularly stable to light and washing.
