The invention relates to a hair styling device, and in particular to a hair straightener. The hair styling device (10; 210) has a first arm (12; 212) and a second arm (14; 214), the first and second arms being moveable relative to one another between a closed or operative condition and an open or inoperative condition. The first member (12; 212) has a first heating panel (16; 116; 216) and the second member (14; 214) has a second heating panel (18; 118; 218). The heating panels (16, 18; 116, 118; 216, 218) are corrugated to increase the length of the path the hair must take between the heating panels. The first and second heating panels are spaced apart in the operative condition so as not to press or clamp the hair therebetween. The first member (12; 212) also has a first pressing panel (26; 126; 226) and the second member (14; 214) also has a second pressing panel (28; 128; 228), the first and second pressing panels in their operative position engaging so that the hair is pressed between the pressing panels.

A hair styling device is described, having first and second members that are movable relative to one another between a closed operative condition and an open inoperative condition. The first member has a first heating panel and the second member has a second heating panel, the heating panels being adapted to heat a length of hair as the length of hair moves along a heating path therebetween in use, and being spaced apart in the operative condition to avoid pressing or clamping the hair therebetween. The first member also has a first pressing panel and the second member has a second pressing panel. The pressing panels are substantially planar. The length of hair moves along a pressing path between the first and second pressing panels in use. The length of the heating path is greater than the length of the pressing path.

A hair styling appliance for dual supply voltage operation is described comprising a body having at least one arm bearing a hair styling heater (560), wherein the hair styling heater comprises one or more heater electrodes (630,632,634,636) for heating the hair styling heater. A first power input is connectable to a battery power source (564) and a second power input is connectable to a mains powered source (561). The first power input and the second power input are each coupled to at least one of the one or more heater electrodes. Such a hair styling appliance is useable for styling when coupled to the mains powered source and when coupled to the battery power source increasing the versatility of the appliance.

A hair treatment or styling apparatus adapted to impart a straightening and/or curling effect on hair includes both a novel thermally conductive construction and heating assembly, which conveys thermal energy uniformly to all areas of the treatment head such that the desired style is achieved regardless of the skill of the user. The apparatus further includes a hinge assembly incorporating one or more ceramic bearings units which provide smooth consistent resistance for pivoting movement of the treatment members and a more durable hinge joint thereby increasing the life and usability of the apparatus.

In a hair straightener comprising an elongate straightener arm (A) having a heating plate (H), the invention provides a pivot mechanism (2) for supporting the heating plate (H) in a pivotable manner around a pivot axis (P1) in a longitudinal direction of the elongate straightener arm (A). Preferably, the pivot axis (P1) is at a heating surface of the heating plate (H), or between a first heating plate of a first straightener arm and a second heating plate of a second straightener arm when the first straightener arm and the second straightener arm are in a relative position arranged for clamping hair. Advantageously, a bias mechanism (4) (e.g. a resilient member like some spring) biases the heating plate (H) to a neutral position.

A capsule-type heater device is provided. According to the present invention, a heating means is made from silicon carbide such that the durability thereof can be improved compared with a heating means made from metals, and a heating means is arranged inside a pair of ceramic cases so as to improve heat exchange efficiency of a thermal medium including air, which passes through the ceramic cases, thereby maximizing energy efficiency.

A hair styling device comprising: a styling substrate; and a coating disposed onto the styling substrate, the coating including: one or more ceramic minerals, and one or more graphene materials in a sufficient amount so that the coating has a thermal conductivity of about 7 Watts/(meter.Math.Kelvin).

A hair brush for use in a hairdressing store, a beauty shop, or at home, is able to easily and freely create a hair style by arranging frictional brush pins to a brush portion of the hair brush so that the hair is easily entangled around the brush portion. A plurality of frictional brush pins are aligned in line to form a frictional brush pin array in a longitudinal direction of the brush portion. Further, a plurality of frictional brush pin arrays are arranged in a circumferential direction of the brush portion at a predetermined interval. A constricted portion is formed between adjacent frictional brush pins so that the hair is entangled by the hair brush due to the constricted portion.

The application describes hair styling apparatus (1) for creating volume in a user's hair. The hair styling apparatus (1) comprises a heating member, a cooling member adjacent to the heating member, thermal insulation between the cooling member and the heating member and a tensioning member projecting from the heating member. The heating member comprises a heating contacting surface for heating hair in contact with the heating member. The cooling member has a cooling contacting surface for cooling hair in contact with the cooling member and the cooling member is cooled by an active cooling mechanism. The tensioning member tensions a user's hair against the heating contacting surface to improve heat transfer into a user's hair and applies stress to a user's hair as the hair contacts the cooling contacting surface adjacent the heating contacting surface whereby the hair is styled to create volume.
