Abstract

A formula delivery system can be used in conjunction with hair and scalp treatment appliances to supply a hair treatment formulation to the appliance. In one aspect, the formula delivery system delivers hair coloring formulation to the appliance. Formula delivery systems of the present disclosure generally include at least one fluid container configured to retain a volume of formulation for delivery of the formulation to a hair coloring appliance. In this regard, the formula delivery system may be configured to removably couple to an inlet member of the appliance that allows the appliance to draw the formulation from the fluid container for use within the appliance.
