One aspect of the present invention is concerned with a method of manufacture of a hair brush. The method has the steps of providing a base member having connection means at circumferential region thereof, providing a sheet material having a plurality of spikes extending from outwardly facing surface of the sheet material, the sheet material and the spikes are integrally formed by injection molding of a plastic(s) material selected from the group consisting of thermoplastics polyester elastomer (TPE-E), polyether block amide copolymer (TPE-A), thermoplastic polyurethane (TPU) and polyurethane (PU), with a hardness from substantially Shore D50 to D65, and with a flexural modulus from 30,000 PSI to 40,000 PSI, assembling the sheet material by fitting perimeter thereof to the circumferential region of the base member, the base member and the connection means are configured to allow the sheet material to secure to the base member. The outwardly facing surface assumes a convex curvature. In an assembled configuration, a cavity is defined between the sheet material and the base member. In use, when the spikes are under pressure the spikes are movable in response to the pressure, causing corresponding movement to the sheet material, the movement creating a cushioning effect.
