  • Patent number: 12138330
    Abstract: An additive is disclosed for use with existing hair coloring products that combines multiple hair dye sources and classifications to create a single precise color tone on demand. The additive salvages chemical parts from existing hair coloring products to create a multitude of new hair coloring options. The additive perfects the dye diffusion process using physics, electrochemical technology and chemical screening technology. The resultant additive mixed with an existing hair product solves many of the problems within the hair coloring industry and enhances safety through lower toxicity.

  • Patent number: 11123281
    Abstract: Disclosed in this application is a hair coloring additive and method of use that provides highly accurate and long-lasting hair coloring results. In some aspects, the hair coloring additive uses raw oxidation dye molecules that are sized to enter into the cortex of the hair during the method of application, where they grow and remain trapped. The hair coloring additive and methods of use can be used with multiple types of hair coloring donor products or formulas, including temporary, semi-permanent, demi-permanent and permanent hair colors.

  • Patent number: 8322353
    Abstract: A hair treatment foil includes a first hook fastener anchoring strip aligned with and proximal to a leading edge of the foil, and a second hook fastener anchoring strip offset from the first strip, the hooks of the second anchoring strip being taller and less dense than the hooks of the first anchoring strip. In embodiments, the hooks of the first anchor strip are offset or randomly placed, and/or the hooks of the second anchor strip are aligned or arranged in a mechanical weave pattern. A push flap is included for urging the foil forward after attachment. The leading edge may be pinked for picking and placing hair on the foil. Shoulders wider than the leading edge may be included. Embodiments include a retaining appliance having a base plate with a hooked fastener anchor strip attached to its underside and a pinked edge for picking of hair from underneath.

  • Publication number: 20070119473
    Abstract: A hair treatment kit has a hair foil, a hair holding appliance, and a tool for selecting hair to be treated. The hair foil may have a hook fastener anchoring strip aligned with the leading edge of the foil. The leading edge may be pinked to provide slots for picking and placing hair on the foil. The shoulders of the foil may be wider than the leading edge and may have a push flap for urging it forward. The retaining appliance has a base plate, the underside being partially configured with one component of a hook and loop fastener system, and a pinked edge to facilitate picking of hair from underneath. The selection tool has a rounded, pointed tip for picking hair, a flat, slightly curved, shaft, and a chemical applicator comb. The shaft may be rotated and inserted under the flap while the foil is being urged forward.

  • Patent number: 6863076
    Abstract: A foil for use in hair coloring is made of a substantially rectangular sheet of material. The upper edge of the foil is pinked, forming a zig-zag pattern. The upper surface of the foil contains a hair restraint in proximity to the foil's upper edge, formed of an elongated, rectangular strip of loop material which adheres to the hair. The lower surface of the foil contains a similar elongated rectangular strip of loop material, providing an attachment anchor, which adheres to the scalp of the subject without the stylist having to hold the foil during the entire coloring process. After the foil has been attached to the subject's hair in proximity to a part, hair strands are woven from under the foil, over the upper edge, and held in place by the hair restraint. Coloring is then applied, and the foil folded in half, retaining the hair within the folded foil.
