The invention concerns a method for treating hair keratin fibres to provide them with new appropriate properties, comprising the following steps: reducing the sulphur bonds of hair keratin to generate, only at the surface of the fibres at a depth less than 10 µm. reactive sites and in fixing covalently on said reactive sites at least one active compound for providing the hair keratin fibres with new appropriate properties, said active compound containing at least a reactive function capable of reacting with said reactive sites formed at the keratin fibre surface. This method is applicable to the treatment of fibrous or non-fibrous keratin substances of human or animal origin.
