Benefits of technology

[0019]Preferably the sides of the second container narrow below the opening to form a neck within the container. As a consequence of the neck formation a lip is formed within the second container which facilitates removal of excess composition from the fingers.
[0020]Preferably at least one part of the second container is deformable, this allows for gas formation within the container to be accommodated without rupture of the container.
[0038]The compositions may comprise a thickener in an amount sufficient to provide the colorant composition with a viscosity so that it can be readily applied to the hair without unduly dripping off the hair and causing mess. Typically, such an amount will be at least about 0.1 percent, in some embodiments, at least about 0.5 percent, in other embodiments, at least about 1 percent, by weight of the colorant composition.

Problems solved by technology

The containers described above do not enable the consumer to apply the colouring product to the hair in this manner.
