The coating with tourmaline ions reduces static charge in the hair. The cuticle layer that envelops each individual hair is closed, effectively preventing hair from drying out. The result is healthy, radiant shine and improved manageability. Especially during regular blow-drying or the use of other heat-based techniques, ionized brushes offer the best protection. Boar bristles have been a proven natural product for decades and are a hallmark of quality in high-end brushes. The 100% pure boar bristles used by Olivia Garden smooth the hair while styling, giving it radiant shine and volume. The ceramic coating of Olivia Garden brushes provides a significant advantage: the ceramic material ensures that the heat from the blow dryer is distributed evenly and quickly throughout the entire brush body. Large air holes also contribute to better airflow. The result is significantly faster, more precise, and therefore gentler styling.
