1. A device for styling hair, the device comprising:
a solid flat top surface, from which an array of bristles independently extend, each from a base to a free end;
at least some or all of the bristles comprising a first-portion which tapers from the base and a second portion which extends from the first portion to the free end, wherein the first portion is wider relative to the second portion, and has a non-circular transverse cross-section at its base which gradually transitions to a circular cross section at which it meets the second portion, the bristles being arranged in two or more spaced apart, offset, rows; further wherein at least one of:
a) in at least half of the rows, centre lines of the rows are spaced apart such that at least part of the first portion of bristles in one row extends between adjacent bristles in an adjacent row, the bristles are sized and arranged so that, in use, the second portion serves to penetrate and divide hair between the bristles and the first portion of the bristles enables tension to be applied to the hair when hair flows between the bristles; and
b) when viewed perpendicular to the rows, in at least half of the rows, the width of the first portion of the bristles in one row is, over part of their length, the same or greater than the space between adjacent bristles in an adjacent row so as to partially occlude the space between bristles in an adjacent row, the bristles are sized and arranged so that, in use, the second portion serves to penetrate and divide hair between the bristles and the first portion of the bristles enables tension to be applied to the hair when hair flows between the bristles.
