Abstract

A formula delivery appliance can be used for treatment of the hair and scalp, such as an appliance used to color hair.

In this regard, the consumable assembly may include one or more formulation delivery packets, nozzles, manifold chambers, distribution protrusions, and the like. The hair treatment appliance may also include a rotatable coupling having a driven gear and a drive gear, where the driven gear may selectively engage the drive gear.
