A hair-shaping device comprising a winding core, a rotatably drivable entraining element with an axis of rotation which corresponds to the longitudinal axis of the winding core, the entraining element designed to grasp a strand of hair and to wind the strand of hair around the winding core, and a housing that encloses the winding core, wherein the radial distance of the inside of the housing from the lateral surface of the winding core in the region of a winding space is sufficiently large such that winding the strand of hair onto the winding core is not hindered. The housing comprises a slot extending in the direction of the longitudinal extent of the winding core. The entraining element is arranged inside the winding space. The slot is designed for inserting a segment of hair to be shaped into the winding space and extends into the housing part facing the hair pull-in side and bounding the winding space in this direction, such that a strand of hair inserted into the insertion slot is caught by the entraining element rotating inside the winding space. The housing has a warm air flow inlet for supplying heat to a strand of hair located in the winding space between the winding core and the housing.

A hair styling device comprises an optical radiation source (L) for radiating hair (H), a sensor unit (S) for measuring effects from radiating hair (H), and a feedforward control device for controlling the optical radiation source (L) in dependence on a signal from the sensor unit (S). The optical radiation source (L1, L2) may produce a first flash having a first energy density that may be lower than required for photo-thermal hair reshaping, the optical radiation source being controlled to produce a subsequent flash in dependence on a sensor signal obtained in response to the first flash, which subsequent flash may have at least the first energy density. The sensor unit (S) may include a sensor arranged before the optical radiation source in a hair flow direction. The hair styling device may comprise, along a direction in which the hair (H) is guided, a first sensor (Si), a first LED unit (L1) being controlled in dependence on a signal from the first sensor (Si), a second sensor (S2), and a second LED unit (L2) being controlled in dependence on a signal from the second sensor (S2). The direction in which hair is guided through the hair styling device may determine which part of the optical radiation source will act as the first LED unit (L1). The hair styling device may comprise a drive mechanism (D) to move the hair (H) along the optical radiation source (L) at a speed controlled by the feedforward control device in dependence on the signal from the sensor unit (S).

A barrel for a hair styling appliance, the barrel comprising: an external surface; and a heater-mounting surface inside the barrel; wherein the heater-mounting surface is integrally formed with the external surface. For example, the barrel may be formed as a single extruded metal component. Also provided is a barrel assembly comprising such a barrel, and one or more heater elements mounted on the heater-mounting surface. Also provided is a hair styling appliance (e.g. a curling tong, curling wand or hot iron brush) comprising such a barrel assembly. A heater element for a hair styling appliance is also provided, the heater element comprising a substrate having a conductive track for generating heat upon application of an electrical current thereto, and an integral temperature sensor. Manufacturing methods in respect of the above are also provided.
