| abstract |
There is disclosed a method of coloring an external surface 10 of a keratinous fibre, such as hair, the method comprising: (a) applying, on the external surface 10 of individual fibres, a formulation comprising: (i) water; (ii) a reactive condensation-curable film-forming amino-silicone pre polymer that, subsequent to condensation curing, forms an elastomer; (iii) a plurality of sub micronic pigment particles; (iv) a dispersant; and optionally, (v) a cross-linking agent and/or (vi) a curing accelerator or catalyst. The partial condensation curing of the pre-polymer can be effected at a temperature of up to 45°C, to form an at least partially cured pigmented film on the external surface 10 of the fibre. Following the partial condensation-curing, the fibres can be washed. Suitable compositions and kits including the same are also disclosed. |
