Abstract: In some embodiments, the present disclosure provides a personalized cosmetic formula preparing system, a method of operating the system, and computer readable instructions for implementing the method. The system determines a personalized cosmetic formula for a consumer. In an embodiment, the determination is based on the consumer's preferences, lifestyle, and cosmetic attributes. The system comprises one or more beauty assessment devices, a digital hub in communication with the one or more beauty assessment devices, a dispenser, and a mixer. The system may be used directly in communication with the consumer, or may automatically obtain the formula from other sources. The companion app may control the constituent elements of the system remotely via the digital hub. The formula preparing system may cause a personalized cosmetic formula to be prepared and packaged without complex or expensive equipment and without extensive cosmetic technical training for the operator of the system.

Abstract: A system is provided that includes a hair dryer; a hairbrush; and a client device. The hairbrush is configured to sense a characteristic of at least one of the user's hair and the hair dryer, and to transmit information back to the hair dryer based on the sensed characteristic, and the client device is configured to communicate with the hair dryer and provide feedback to the user regarding a user's usage of at least one of the hair dryer and hairbrush based at least in part on sensed characteristic captured by the hairbrush.

Abstract: An instrumented comb, including bristles protruding from the handle, the bristles spaced apart from each other such that a first set of two or more bristles are spaced by a first distance, a second set of two or more bristles are spaced by a second distance, and a third set of two or more bristles are spaced by a third distance, wherein the third distance is greater than the second distance and the second distance is greater than the first distance. The comb includes a controller receiving signals from: a contact sensor to detect contact with a scalp, and a magnetic compass to determine location on the scalp. The comb uses the signals to record the detected contact information and determined location information as the comb undergoes a brushing gesture over a scalp, measure hair density based on the contact information and location information, and output the measured hair density.

Abstract: A method, system, and device for measuring and evaluating hair loss over time is disclosed. A instrumented comb device includes a power source, a controller, and associated sensors. The controller receives signals from the sensors, including a contact sensor to detect contact with a scalp and obtain a hair count, and a magnetic compass to determine location on the scalp. The controller includes one or more processors that acquire and record the detected contact information and determined location information as the comb device is stroked over a scalp, and measure hair density based on the contact information and location information. The instrumented comb can communicate with a remote information system or a mobile device for auxiliary processing and display. Machine learning of the remote information system allows for recognizing hair density or prediction of future trends in hair density over time using data recorded by the sensors.

Abstract: An apparatus to realize personalized cosmetic compositions including a formula supply assembly having a plurality of additive reservoirs that contains a plurality of additive substances, a plurality of additive pumps that supplies selected additive quantities of the plurality of additive substances, a base reservoir that contains a base substance, and a base pump that supplies a base quantity of the base substance and a mixing assembly having an additive inlet that receives the selected additive quantities, a base inlet that receives the base quantity, and a mixing channel that mixes the additive quantities with the base quantity to form the personalized cosmetic compositions.

Abstract: A system is provided that includes a hair dryer; a hairbrush; and a client device. The hairbrush is configured to sense a characteristic of at least one of the user's hair and the hair dryer, and to transmit information back to the hair dryer based on the sensed characteristic, and the client device is configured to communicate with the hair dryer and provide feedback to the user regarding a user's usage of at least one of the hair dryer and hairbrush based at least in part on sensed characteristic captured by the hairbrush.

Abstract: A system is provided that includes a hair dryer and a hairbrush. The hairbrush is configured to sense a characteristic of at least one of the user's hair and the hair dryer, and to transmit information back to the hair dryer based on the sensed characteristic. The hair dryer is configured to update at least one setting, which may include least one of temperature control, air flow speed, and air flow shape at the hair dryer, based on the received sensed characteristic.

Abstract: A system that includes a styling tool configured to treat or shape a user's hair; and a client device configured to communicate with the styling tool and provide feedback to the user regarding a user's usage of the styling tool based at least in part on measured data captured by the styling tool. The styling tool may be a hairbrush that includes circuitry and/or sensors configured to detect one or more of sound, acceleration, force, rotation, hair humidity, and ambient temperature and humidity.
