Simple maintenance of your hair brushes can go a long way towards achieving the very best results in your hair care efforts. To maintain your brush, regularly condition the bristles with a natural oil such as jojoba or sweet almond oil. This will help the bristles remain soft and prevent them from becoming brittle. Remove excess oil by lightly massaging the bristles with a clean cloth. For deeper cleaning, soak the brush in warm water mixed with a mild shampoo or brush cleaner overnight before rinsing out with warm water and patting dry.
