1. A formulation delivery head, comprising:
a formula delivery head housing, comprising:
a manifold chamber defined within the formulation delivery head housing and having a fluid inlet in fluid communication with a first formulation fluid source;
a peristaltic pump comprising a plurality of rollers configured to cause a first formulation to flow from the first formulation fluid source to the manifold chamber;
a plurality of outlet nozzles extending from the manifold chamber, wherein each outlet nozzle of the plurality of outlet nozzles comprises an outlet aperture at a distal end of the outlet nozzle, and wherein the outlet nozzle is configured to discharge the first formulation from the manifold chamber through the outlet aperture;
a plurality of standoff protrusions extending outwardly from the formulation delivery head housing substantially in the direction of the plurality of nozzles, wherein the length of each of the plurality of standoff protrusions is longer than the length of each of the plurality of nozzles such that outlets of each of the plurality of nozzles are spaced away from an application surface; and
a distribution protrusion extending into the manifold chamber and configured to direct the flow of the first formulation from the fluid inlet to each of the plurality of outlet nozzles,
wherein the formulation delivery head is configured to removably couple to a powered handle assembly.
