    TLDR Adding human and horse hair fibers to concrete can increase its strength.
    In 2020, a study was conducted by Zakaria Hameed Awadallah Ibrahim to investigate the mechanical properties of concrete reinforced with human and horse hair fibers. The research aimed to improve the tensile properties of concrete, a material known for its brittleness, by using hair fibers, a cheap and abundant non-degradable material. The experiments involved concrete cylinders, cubes, and prisms with varying percentages of human and horse hair fibers (0%, 1%, 1.5%, and 2.5% by weight of cement) and two grades of reference plain concrete (20 and 40 MPa). The results indicated an increase in various mechanical properties and strength of concrete with the addition of human and horse hairs.

      Accepting hair loss and not taking drastic measures like shaving your head if you are only mildly balding, and encouraging people to fight it with treatments such as finasteride, minoxidil, nizoral and microneedling. Additionally, it discusses the importance of being realistic when trying to restore hair and addressing the misconception that one must look a certain way in order to be attractive.
