March 2017 in “International journal of GEOMATE : geotechnique, construction materials and environment” This study found that incorporating pig-hair fibers and green mussel shells in concrete increased compressive strength but decreased workability, suggesting potential use in structures not requiring strength above 28 MPa.
August 2016 in “International journal of scientific research in science, engineering and technology” This study demonstrated that incorporating human hair fiber into soft clayey soil significantly enhances subgrade strength and reduces cracking compared to unreinforced soil, as confirmed by unconfined compressive strength and CBR tests.

July 2018 in “Journal of Testing and Evaluation” This study found that human hair fibers significantly improve the shear behavior of dry sand, but under saturated conditions, the reinforcement sustains shear strength similar to unreinforced sand.

August 2017 in “PLOS ONE” This study reports that the mechanical interactions between human skin and adjacent subcutaneous white adipose tissue influence the appearance of skin wrinkles, with sWAT reinforcement potentially more effective for reducing signs of skin aging than skin reinforcement alone.
