Our Everyday Extension Brush, is constructed with 100% wild boar bristles, nylon & a wooden base. We love using wood for our brushes as they are antimicrobial and antibacterial to fight off any unwanted germs. This brush was created with two types of bristles that touch your hair when brushing. Boar bristles offer a soft natural fibre + then the nylon gets deep into your extensions. We recommend this brush for everyday use for all extension wearers.
