1. A formulation delivery system, comprising:
a reusable handle to reversibly receive a formulation cartridge comprising a formulation therein and a cleaning cartridge comprising a cleaning liquid therein to remove residual formulation from the formulation delivery system;
a formulation dispensing assembly including a reciprocating nozzle assembly and a pump, the reciprocating nozzle assembly fluidically-coupleable, via one or more fluid conduits, to the formulation cartridge, or the cleaning cartridge, received within the reusable handle;
a controller including computational circuitry and logic to toggle between at least a cleaning routine and formulation routine responsive to one or more inputs indicative of the cleaning cartridge or the formulation cartridge inserted into the reusable handle; and
computational circuitry configured to:
accept and store at least one user profile input;
create, based upon the at least one user profile input, a user-specific routine providing instructions for using the formulation delivery device to apply a formulation to a hair of a user at an interval determined to improve health of the hair of the user; and
display the user-specific routine on a mobile device.
