A hair painting board fosters application of coloring and other hair treatments in an efficient manner. The hair painting board has a curved body to conform to the shape a client's scalp. A wider end of the hair painting board provides the option to a hair stylist to select a variety of hair strands from various areas of the scalp and apply treatment thereto quickly and efficiently. A narrower end is useful for application of treatment at smaller areas of the scalp. One or more notches in the curved body aid in grasping and manipulating the hair painting board.

Embodiments provide an ultrasound treatment system. In some embodiments, the system includes a removable transducer module having an ultrasound transducer. In some embodiments, the system can include a hand wand and a control module that is coupled to the hand wand and has a graphical user interface for controlling the removable transducer module, and an interface coupling the hand wand to the control module. The interface may provide power to the hand wand or may transfer a signal from the hand wand to the control module. In some embodiments, the treatment system may be used in cosmetic procedures on at least a portion of a face, head, neck, and/or other part of a patient.
