Abstract: A dispensing apparatus for dispensing hair products such as developer solution. The dispensing apparatus includes a user interface for interacting with the user by allowing the user to enter desired parameters or for displaying prompts to the user. The user interface also includes a user tracking mechanism such as a card reader or a key pad where identifying information can be communicated to the apparatus. Data pertaining to each dispensing transaction is processed by the controller and communicated to a database, wherein the information is stored for retrieval at a later time. User data can be used by the business owner to manage his business more efficiently. The user may enter the desired dispensing parameters which are communicated to the dispensing mechanism. A reservoir containing developer solution is connected to a pump which, in conjunction with a central controller, regulates the dispensing of developer solution.
