Natural, plastic-free bamboo hairbrush that's better for your hair This fully biodegradable, plastic-free bamboo hairbrush (even the pins are 100% bamboo!) will not damage the hair like a standard plastic pinned brush. It has completely smooth edges and cushioned bristles with rounded ends – perfect for gentle, nick free, detangling and will help create a sleek and shiny finish. Size: Bamboo brushes create less static. Cue the science. Plastic brushes increase the electrical charge so as it slides through, the charge is transferred to your hair and you get static. Bamboo has a neutral charge, so static is reduced (or often disappears), which is basically much more ‘zen’ for your hair and allows it to lay down (or up) and chill.
