Handheld motorized hair styling device
View Patent ↗The handheld motorized hair styling device is a battery-operated, motorized, hair styling tool that produces a styled pattern of curls, twists, and/or coils in hair. The handheld motorized hair styling device creates the styled pattern by moving a contoured styling pad against the hair in a roto-linear motion. The speed and direction of the roto-linear motion may be changed using controls on the handheld motorized hair styling device. The styling pad may be removed and replaced and the battery is rechargeable.
