A hairbrush device includes a limited-excursion, rotating brush head with continuously variable rotational resistance, thereby minimizing tugging-related damage while brushing hair using a simple stroking motion. Thick or tangled hair engages the bristles causing the brush head to rotate from a resting position. A spring means provides increasing resistance in concert with increased rotation of the brush head. When the bristles are removed from the hair, the spring means returns the brush head to its resting position for the next stroke. Preferably, the spring means includes a brush connector releasingly affixed to interchangeable brush heads and releasingly and rotatingly affixed to interchangeable handles. An effective length limiter grips a flat torsion bar affixed to the connector and a shank extends from the gasket axially through the brush handle. A conventional spring release and track within the handle allow the limiter to be moved longitudinally along the torsion bar to increase or decrease resistance. Also preferably, the handle and connector provide an integral brush head rotation limiting means, thereby preventing over-rotation and resultant damage. Closed or open-ended handles provide for singular hairbrush, comb or pick, as well as curling iron, hair dryer and similar conventional hairbrush type applications. Bidirectional operation allows left and right handed users to wave through hair and to impose ratting effects through back-brushing.
