This project is within a private property in the Moraga area in California. It aims to demonstrate the potential of human hair mulch and hair scrims in soil remediation and stabilization efforts. This project will evaluate the structural integrity of a variety of felted hair scrims over soil and vegetation conditions. We will also be evaluating efficacy in regards to thickness/weight of particular hair scrims/mulch per square foot and associated benefits. The study will include the sorting and felting of these natural fibers, the installation of hair mulch and hair scrims, and the scattering of white clover and California poppy. Past research has shown that hair mulch and scrims increase water retention and reduce evaporation, conducive to increased plant growth and soil stabilization. 

Over time, with documentation and follow-ups every 3-6 months over a minimum of the next 3 years, we aim to observe how the scrims promote biomass, root development, and erosion reduction. We are curious to see how the scrims with seeds repopulate the eroded hillside with native vegetation, hopefully contributing to the ecosystem of the entire area. We expect that in the areas where there are hair scrims, there will be enhanced soil fertility and reduced soil compaction. Additionally, we are curious to see whether improvement in soil health differs with the different test scrim densities and weaves.

Hair Mulch is 100% natural, biodegradable soil amendment made from recycled hair, fur and wool fibers from households, salons, groomers, shelters, ranchers, recyclers, wigmakers, wool spinners, mini mills and more. Hair contains keratin, a protein that breaks down slowly, releasing nitrogen into the soil, adding carbon and increasing water retention. Unlike traditional mulches, hair decomposes over years, enhancing microbial and fungal activity, attracting moths, butterflies, and increasing soil fertility.
