Abstract: A system is provided for generating a custom hair dye formulation to be dispensed into a single customer container for a particular customer. The system establishes a connection with a user device of the particular customer over a network, receives a selection of a preferred type of expertise of a colorist, determines an available colorist that corresponds to the preferred type of expertise, establishes a video communication session between the particular customer and a colorist device of the determined colorist, causes display of a customer interface to the customer, causes display of a colorist interface to the colorist device, and transmits the generated custom hair dye formulation to a fill site, via the network.

Abstract: The present disclosure relates to color base compositions, as well as methods and kits using same. Certain compositions comprise: (a) about 0.05 to about 10 wt. % of at least one 3-aminopyrazolo[1,5-a]pyridine; (b) from about 0.01 to about 1 wt. % of a reducing agent other than thiolactic acid; (c) from about 0.01 to about 5 wt. % of an ammonia compound; (d) from about 5 to about 10 wt. % of an alkanolamine; (e) from about 0.01 to about 6 wt. % of a carboxylic acid-containing surfactant; and (f) from about 0.01 to about 1 wt. % of an antioxidant.
