The VitalHair Brush's nano-mist technology is designed for precision and effectiveness. It works by emitting a micro-fine mist that deeply penetrates the hair cuticles and scalp. Here’s how it works: Fill the reservoir with our rosemary oil elixir, and with a simple press of a button, the brush releases a delicate mist that wraps each strand in nourishing moisture. This not only provides deep hydration without weighing down your hair but also ensures that the nutrients are absorbed efficiently, maximizing the health benefits to your hair and scalp.
