Patent number: 11330885Abstract: The multi-functional hair drying net and turban towel for upright application may be used on its own or so combination with a hand held hair dryer. Useful for managing dry and wet hair, to absorb water from wet hair after washing, swimming, or anytime the hair is wet, thereby avoiding dripping of water on the face, neck, or clothes. Used over dry hair to keep hair off the face, back and neck when applying make-up and treatments to the face. When required to dry hair by electrical means the device can be connected to a commercially available hair dryer and used as a conduit to direct warm air into the net cavity and dry hair using electrical means. It can be used to keep hair dry and off the face and back in the bath, shower, Jacuzzi spa or steam bath.Type: GrantFiled: May 23, 2016Date of Patent: May 17, 2022Inventors: Aurora Walker, Andrew Peter Walker
