Human Hair: The Eco-Friendly Solution Revolutionizing Oil Spill Cleanup
How human hair mats and booms are changing the future of oil spill cleanup efforts globally.
Human Hair: The Surprising Weapon Transforming Oil Spill Cleanup
Oil spills are notorious for their devastating environmental impacts, contaminating water sources, harming wildlife, and posing long-term risks to entire ecosystems. Traditionally, dealing with oil spills has relied heavily on synthetic materials and chemicals. But what if one of the best solutions was right under our noses—more precisely, growing out of our heads? Human hair mats and booms have emerged as a remarkable, sustainable, and highly effective tool in cleaning up oil spills worldwide.
Why Oil Spills Are So Dangerous
- Water Contamination: Even a small quantity of oil can pollute vast amounts of water. For example, a single quart (approximately one liter) of oil has the potential to contaminate up to a million gallons (3.8 million liters) of drinking water.
- Biodiversity Loss: Oil spills suffocate marine life, erode shorelines, and disrupt entire food chains, with long-lasting consequences for the health of oceans and local economies.
- Clean-Up Challenges: Oil is difficult to remove from water using conventional synthetic booms and chemical agents, which may pose their own environmental risks.
The Unique Properties of Human Hair for Oil Adsorption
Human hair has a naturally porous structure and is highly adsorbent, making it especially effective at capturing oil—far superior to simply absorbing it. The difference lies in the molecular interactions:
- Adsorbent, Not Absorbent: Hair doesn’t act like a sponge that soaks up oil; instead, oil molecules coat the exterior of each hair strand, creating a sticky film that efficiently captures and retains oil.
- Surface Area: Each strand of hair offers a vast surface area for oil molecules to adhere, making hair mats densely effective in a compact space.
- Porosity: The microscopic texture and structure of hair allow it to bind various types of oil waste rapidly and efficiently.
Scientific Validation
The performance of human hair as an oil sorbent has been validated by multiple studies and organizations:
- A landmark discovery by Alabama hair stylist Philip McCrory in 1989 led to subsequent testing by NASA, confirming that human hair can effectively capture oil from water.
- A 2018 study from the University of Technology Sydney concluded that untreated human hair booms are “significantly better” at adsorbing crude oil compared to materials like cotton and cellulose.
From Salons to Shorelines: The Birth of a Movement
The journey from idea to global impact was sparked in the aftermath of the Exxon Valdez spill when Philip McCrory observed how otter fur, matted with oil, inspired the use of salon hair waste for cleaning up oil. The organization Matter of Trust, founded by Lisa Gautier and Patrice Gautier in 1998, was instrumental in bringing this idea to scale.
- Early Experiments: McCrory stuffed five pounds of salon hair into pantyhose and performed home tests, proving that hair mats could soak up oil in a backyard pool.
- Scaling Up: Matter of Trust created a felting machine to manufacture large quantities of two-foot square mats, each capable of adsorbing about 1.5 gallons (5.6 liters) of oil using only 1.1 lbs (500 grams) of hair.
- Community Engagement: Nearly a million U.S. salons donate their daily hair trimmings, as do thousands of individuals from all fifty states, ensuring a reliable stream of supply for eco-friendly oil cleanup endeavors.
- Diverse Fibers: Alongside human hair, Matter of Trust uses other reusable fibers such as pet fur, fleece, and even laundry lint, further boosting its eco-credentials.
International Success Stories: Hair Mats in Action
The scalability and effectiveness of hair mats have enabled successful global deployment for oil spill response efforts:
- The Galapagos Spill: The concept earned global credibility in 2001, when hair mats played a major role in cleaning up an oil spill in the Galapagos Islands.
- Deepwater Horizon Disaster: During the infamous 2010 Gulf of Mexico spill, Matter of Trust distributed over 300,000 oil cleanup booms and 40,000 mats, fighting off one of the worst environmental disasters in recent history.
- Philippines: A nationwide drive in 2006 involved inmates and communities collecting hair for cleaning up 189,000 liters of industrial fuel, proving how rapidly hair-based solutions can be mobilized in emergencies.

Advantages of Hair Mats and Booms Over Conventional Methods
- Eco-Friendliness: Unlike synthetic polypropylene booms, which are petroleum-based and non-biodegradable, hair mats use a renewable resource and minimize landfill waste.
- Scientific Efficacy: Hair mats consistently outperform many commercial alternatives in adsorbing spilled oil per gram of material.
- Cost-Effectiveness: Hair waste is typically available free or at negligible cost, lowering the barrier to eco-friendly cleanup operations.
- Waste Reduction: Redirects tons of salon waste from landfills into productive use by upcycling hair clippings.
Challenges and Limitations
- Disposal Issues: Used hair mats must be properly managed. Composting and incineration are two current options, but both have environmental drawbacks.
- Buoyancy Concerns: Mixed human hair compositions sometimes result in mats that are less naturally buoyant, requiring special casing or floatation devices to perform optimally in water.
- Preparation Matters: Hair must be carefully prepared to avoid introducing contaminants to the environment. Not all donated hair qualifies for use in oil spill cleanup, as guidance from authorities like the Philippine Coast Guard has highlighted.
Innovation and Future Directions
Matter of Trust and supporting researchers are pursuing new ways to improve the technology, including:
- Developing methods to extract oil from hair mats so they can be reused multiple times, increasing sustainability.
- Enhancing mat buoyancy with surface modifications and floatation devices for more reliable performance in diverse environments.
- Extending the approach to other waste fibers such as pet fur, fleece, and even laundry lint, broadening the impact.
- Active research in Australia and globally continues to validate and optimize hair-based booms and mats for oil spill response.
Community and Environmental Impact
Hair mat technology is distinct in its grassroots engagement, leveraging widespread community involvement to tackle major ecological threats:
- Volunteerism is vital, rallying individuals, salons, pet groomers, and entire communities to contribute waste hair for a shared environmental cause.
- The system embodies the “circular economy” principle by upcycling a readily available resource into something that cleans and protects the planet.
- Collaboration between scientists, engineers, salons, and conservationists exemplifies how innovators and everyday people can work together for environmental progress.
