In a hair setter apparatus, a heater assembly is enclosed within a housing. The heater assembly has a longitudinal heat delivery rail mounted in the housing and having a longitudinal axis. The longitudinal heat delivery rail includes a groove extending longitudinally along at least part of the heat delivery rail. A corresponding hair setter has a central body having opposing web plates spaced from each other to define a mounting slot extending longitudinally of the hair setter. The mounting slot is configured to engage the groove of the heat delivery rail upon mounting the hair setter thereon to slidably couple the hair setter to the heat delivery rail for sliding movement longitudinally of heat delivery rail while inhibiting decoupling of the hair setter from the heat delivery rail in a direction transverse to the rail.

A system comprises implements, each including a body, a receptacle disposed on one end of the body and having a bore and an aperture formed through spaced apart wall portions of the receptacle, a clip pivotally attached to the elongated body, and a spring operable to bias the clip for a contact with the elongated body. An applicator handle includes a body having a hollow interior and an end thereof sized and shaped to fit the bore of the receptacle, a resilient member disposed within the hollow interior, a pair of pins upstanding on the ends of the resilient member and sized to be received within the aperture and two buttons engageable with the resilient member and mounted for a linear movement, the two buttons are manually operable to move the pins toward each other for a selective engagement or disengagement of the pins with the aperture.
