Medium size wooden brush (18 cm), pure wild boar bristles and white nylon studs. This French-made brush is made of 100% natural materials. * The wood comes from sustainably managed forests. * The latex in the pneumatic pad is natural: it is made from rubber tree sap. This sap has the particularity of being elastic and adapting to the shape of the skull. This allows for a gentle and pleasant massage on your scalp with each use. * On the other hand, the hairs are made of pure wild boar: composed of keratin, they regulate the diffusion of sebum and deeply nourish your hair. * Finally, the nylon studs guarantee optimal combing, without breaking your hair.
