  • Patent number: 5655551
    Abstract: A method of use of an applicator for hair lotions. The applicator has a flat, solid blade that is shaped like a comb. This blade does not have teeth like a comb normally has. One embodiment of the applicator does have a series of small curved teeth, similar in appearance to saw teeth, formed on the front edge of the blade. These teeth enable the applicator to lie flat on coarse hair without difficulty compared to an applicator having a smooth leading edge. The method calls for aligning the front edge of the blade against the hair such that the flat blade is perpendicular to the hair; applying lotion to the hair; catching any spilled lotion on the flat blade of the applicator; rotating the flat blade 90 degrees such that the blade is parallel to the hair; and wiping the lotion accumulated on the flat blade on the hair.

  • Patent number: 5042512
    Abstract: A new form of applicator for hair setting creams or lotions is disclosed. Although this device is shaped like a comb, it has no teeth. The entire head of the applicator is flat and smooth. This allows the hairdresser to use the applicator like an artist uses a palette knife; to apply creams or lotions, smooth it into the hair, and to scrape off any excess. The applicator also has a rat tail handle, typically found on hairdressing combs to allow the hairdresser to work the hair. By alternating between the applicator end and the handle, the hairdresser can quickly and efficiently apply relaxing cream on hair to be straightened, or can separate and curl the hair while applying the setting creams or lotions, without having to stop and change tools.
