Composting Hair: Human, Pet, and Salon Hair as Nitrogen-Rich Greens

Hair is a “green” (nitrogen) material—any undried organic matter not from inside an animal qualifies. Human hair from brushes, dog/cat grooming clippings, and salon sweepings all work. Salons and groomers often give it away for free.

How to Compost Hair

• Sprinkle thinly among other greens—avoid large clumps.
• Cover pile with a tarp to retain heat/moisture.
• Turn a few times weekly.
• Breaks down in ~1 month.

Hair adds nitrogen and helps balance carbon-heavy piles. A free, unusual, but effective ingredient.
