A heated hair paddle, which comprises: a brush head defining a central longitudinal x-axis extending along a length of the brush head, a y-axis orthogonal to the longitudinal x-axis extending along a width of the brush head and a z-axis extending along a height of the brush head; a plurality of first bristles depending from the brush head, the first bristles having a dimension along the y-axis greater than a corresponding dimension along the x-axis to provide an increased surface area along the y-axis of each first bristle, the first bristles comprising a thermally conductive material; a plurality of second bristles depending from the brush head, the second bristles having a dimension along the z-axis greater than a corresponding dimension along the z-axis of the first bristles; a plurality of third bristles depending from the brush head, the third bristles being more rigid than the second bristles; and a heater thermally coupled to the first bristles and configured to convey heat to the first bristles such that the first bristles are thereby configured to convey heat to a length of hair; characterized in that: the first, second and third bristles are each arranged to define a plurality of respective first, second and third rows extending along the longitudinal x-axis of the brush head; and further comprising an inner first row of the first bristles radially outward of each side of the central longitudinal x-axis, an inner second row of the second bristles radially outward of each of the inner first rows of the first bristles, an outer first row of the first bristles radially outward of each of the inner second row of the second bristles, an outer second row of the second bristles radially outward of each of the outer first rows of the first bristles, and an outer third row of the third bristles radially outward of each of the outer second rows of the second bristles. a brush head defining a central longitudinal x-axis extending along a length of the brush head, a y-axis orthogonal to the longitudinal x-axis extending along a width of the brush head and a z-axis extending along a height of the brush head; a plurality of first bristles depending from the brush head, the first bristles having a dimension along the y-axis greater than a corresponding dimension along the x-axis to provide an increased surface area along the y-axis of each first bristle, the first bristles comprising a thermally conductive material; a plurality of second bristles depending from the brush head, the second bristles having a dimension along the z-axis greater than a corresponding dimension along the z-axis of the first bristles; a plurality of third bristles depending from the brush head, the third bristles being more rigid than the second bristles; and a heater thermally coupled to the first bristles and configured to convey heat to the first bristles such that the first bristles are thereby configured to convey heat to a length of hair; characterized in that: the first, second and third bristles are each arranged to define a plurality of respective first, second and third rows extending along the longitudinal x-axis of the brush head; and further comprising an inner first row of the first bristles radially outward of each side of the central longitudinal x-axis, an inner second row of the second bristles radially outward of each of the inner first rows of the first bristles, an outer first row of the first bristles radially outward of each of the inner second row of the second bristles, an outer second row of the second bristles radially outward of each of the outer first rows of the first bristles, and an outer third row of the third bristles radially outward of each of the outer second rows of the second bristles. the first, second and third bristles are each arranged to define a plurality of respective first, second and third rows extending along the longitudinal x-axis of the brush head; and further comprising an inner first row of the first bristles radially outward of each side of the central longitudinal x-axis, an inner second row of the second bristles radially outward of each of the inner first rows of the first bristles, an outer first row of the first bristles radially outward of each of the inner second row of the second bristles, an outer second row of the second bristles radially outward of each of the outer first rows of the first bristles, and an outer third row of the third bristles radially outward of each of the outer second rows of the second bristles.
