 Human Hair Waste As A Nutrient To Plants
Studies have shown that human hair, a readily available waste generated from barbershops and hair salons, combined with additional compost, is an additional nutrient source for crops.

Although human hair has become commercially available to crop producers in the past couple years, it has not been proven to be an exclusive source of nutrients in greenhouse container production.

Now, Vlatcho D. Zheljazkov, Juan L. Silva, Mandar Patel, Jelena Stojanovic, Youkai. Lu, Taejo Kim, and Thomas Horgan of Mississippi State University recently conducted a research study in HortTechnology, designed to determine whether commercially available noncomposted hair waste cubes would support plant growth in horticulture crops as a sole source of nutrients.

The study compared the productivity of four crops: lettuce, wormwood, yellow poppy, and feverfew, grown in commercial growth medium using untreated control, noncomposted hair cubes at differing weights, a controlled-release fertilizer and a water-soluble fertilizer.

Results showed that, with the addition of hair waste cubes, yields increased relative to the untreated control, but were lower than yields in the inorganic treatments, suggesting that hair waste should not be used as a single source for fast-growing plants such as lettuce.

According to Zheljazkov, "Once the degradation and mineralization of hair waste starts, it can provide sufficient nutrients to container-grown plants and ensure similar yields to those obtained with the commonly used fertilizers in horticulture."

Because of possible health concerns, further research is necessary to determine whether human hair waste is a viable option as fertilizer for edible crops.

Great article. Do you know if there already exists a company buying waste hair and selling it? Look forward to hearing from you.
