From Salon to Salad: Human Hair Makes Good Plant Fertilizer
Human hair could be used instead of chemical fertilizers for some plants like lettuce, new research in a horticultural journal suggests.
The hair, which is manufactured into cubes from barbershop and hair-salon waste, provides nitrogen for plants as it decomposes, just as natural-gas-derived sources like ammonia do.
"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," said horticulturalist Vlatcho Zheljazkov of Mississippi State University.
