Lüfka Plastic-free Bamboo Hair Brushes are made from 100% biodegradable materials. Some benefits of using a plastic-free hair brush is Less static –Plastic hair brushes increase the electrical charge of your hair, and as a plastic brush glides through your hair, the increased electrical charge leads to static. Gentler detangling -The bamboo bristles of our no plastic bamboo hair brush are surprisingly soft, smooth and free from sharp corners, so when pulled through your hair, they detangle gently. Shinier Hair -A bamboo hair brush glides through your hair, teasing the natural oils from the scalp along each strand, which results in a shinier, glossier appearance. Massaged Scalp -Our bamboo hair brush with natural rubber cushioning and smooth bamboo bristles stimulate and massage the scalp when you use them. Massaging the scalp increases sebum production, which means softer, shinier hair.
