US Patent No. 844715; Living Proof has been issued a patent related to its innovative hair care products. Three notices of allowance for patents expand Living Proof’s proprietary technology around OFPMA, which is designed to weightlessly smooth, condition, strengthen, polish and extend the quality and appearance of styled hair.

The new patent, “Coloring Agents and Methods of Use Thereof,” covers a hair coloring innovation in Living Proof’s pipeline. The hair coloring innovation brings together, for the first time, two properties that have historically been a tradeoff in hair color products: color brilliance and durability. The claims of this new patent are directed to novel dye compositions.

In a similar way, that molecules are combined for innovative drugs and other molecular structures, the claimed dye compounds in Living Proof’s technology contain three parts: a chromophore which is responsible for the color of the dye; a color-fastness moiety, which is responsible for binding the dye compound to hair; and a linker, which connects the chromophore to the color-fastness moiety, according to the firm.
