LARGE CURVED HEAD: The two hair brush detanglers feature large heads with a meniscus radian design, the combination of a convex curve and a concave curve give both brushes the maximum number of scalp contact points to massage and promote natural oil stimulation. VENTED FOR FASTER DRYING: We designed the large head of our hair brushes with vents to create a more efficient airflow for faster drying while styling your hair with a blow dryer. EASY
