    TLDR Keratin hydrogel from human hair helps rats recover better from spinal cord injuries.
    In a study from 2014, researchers investigated the use of a keratin hydrogel, derived from human hair, as a treatment for spinal cord hemitransection injuries. The study found that rats treated with the keratin hydrogel exhibited higher survival rates, improved gait properties, and better bladder function compared to untreated controls. Histologically, the keratin-treated rats showed reduced glial scar formation, indicating less inhibitory scarring and more favorable tissue remodeling. These promising results suggested that keratin biomaterials could potentially be used for treating spinal cord injuries and called for further research into their application in the central nervous system.

      in Research/Science  15 upvotes 1 year ago
      A gel of keratin microspheres promotes hair follicle growth, showing similar effectiveness to minoxidil in mice. The treatment activates hair growth pathways and reduces inflammation, with potential applications in drug delivery for hair-related disorders.

      OP is considering using a keratin gel to improve hair quality and is concerned about its safety and visual impact on a slightly balding crown. Users discuss shampoo frequency, with some suggesting less frequent use for better hair health, but OP prefers regular shampoo and conditioner for silky hair.
