Abstract: A head for an oral-care implement comprises a number of colored filaments extending from a mounting surface of the head and being grouped together to define an initial color pattern. The colored filaments comprise at least a first and a second type of filament, wherein the types of filaments differ in color-changing characteristics over a pre-defined period of time, the pre-defined period of time being the same for the first and the second type of filament so that the initial color pattern changes color characteristics over at least a first pre-defined period of time to a first color pattern, the first color pattern being different form the initial color pattern.

Abstract: A head for an oral care implement comprises a number of colored filaments of different types. The filaments extend from a mounting surface of the head and are grouped together to define an initial color pattern. At least two types of filament have staggered time-controlled color changing properties, wherein each of said type of filament changes its color within pre-defined time periods, the pre-defined time periods being different from each other so that the initial color pattern changes color characteristics over at least a first pre-defined period of time to a first color pattern and over a subsequent second pre-defined period of time to a second color pattern, the second pattern being different from the first pattern.
