1. A device, comprising:
a treatment system including an air blower and heater to treat scalp or hair;
one or more sensors configured to detect device distance to scalp or hair;
one or more contact sensors configured to detect device contact with the scalp;
a controller configured to send instructions to adjust the treatment system based on the distance of the device to the scalp or hair, wherein the heater and air blower increase a force and temperature of blowing air with increasing distance and decrease the force and temperature of the blowing air with decreasing distance;
the device includes a handle connected at an obtuse angle to a front end of the device, the handle extending in a top to bottom plane, the front end including three tines, wherein the three tines are placed in a side to side plane, wherein a front end of each tine includes a truncated rounded shape, the truncated rounded shape including a chamfered section being a flat area on a bottom facing side of each tine and a rounded shape on top of each tine, wherein the flat area of each tine includes an opening;
a dispenser that dispenses a formulation through the openings in the flat areas of the tines, and the controller controls the dispenser to reduce an amount of the formulation dispensed with increasing distance of the device with the scalp or hair; and
the controller further controls dispensing the formulation as a liquid when contact with the scalp is detected and dispensing the formulation as a mist when no contact with the scalp is detected.
