Regal Bliss Black The Regal Bliss® 4-in-1 Electric Hairbrush is simple and efficient to use for quick styles and natural volume. After plugging in, select one of 3 temperature settings (warm air for drying and styling or cool air for hold). The brush is suitable for all hair types and lengths. The ceramic tourmaline and negative ionization technology reduces electrification and protects the hair, leaving it smooth and shiny. Use the brush on damp or almost dry hair, section by section, to achieve root volume or light waves. After use, turn off and allow to cool before storing.
