How Long Does It Take for Human Hair to Decompose?
Human hair can endure for several years, often 2 years, before decomposing along with softer tissues. Hair, like fingernails, is made of keratin and is much more durable than skin and flesh.
Decomposition is heavily affected by the environment in which it occurs. While most microbes, rodents and insects do not eat hair or fingernails, they can hasten the overall process. In a sealed grave the entire process occurs much more slowly, sometimes on the order of years. If exposure to soil is direct, or if the corpse is left unburied and exposed to the wind, then decomposition occurs with much greater rapidity.
Keratin resists the enzymes that encourage decomposition. This process is called proteolysis and it breaks down fleshy tissue with extreme rapidity. Environmental stress like moisture and invasive plant growth are more influential in destroying keratin, though eventually the process of decomposition does take its toll on the materials involved.
In some extreme cases when a corpse has been preserved through artificial means, hair and fingernails may endure far longer than is typical. This period can last for decades or even centuries, although it requires a very sterile environment and the careful maintenance of the tomb or sepulcher in question.
Decomposition of a corpse is a continual process that can take from weeks to years, a human body in its fat distribution, cover of hair and ability to attract insects.

What happens to the human body after 100 years inside a coffin
- Your brain is one of the first parts of your body to break down. Just a few minutes after death, its cells collapse and release water. Then other energy-guzzling organs follow.
- That night, microbes eat through your gut and escape into the rest of your body. They release toxic gases that cause your body to bloat up and smell.
- Most of your tissues will probably liquify. But thin skin, like on your eyelids, could dry out and mummify, while fatty areas of your body can turn into a soap-like substance called grave wax.

Following is a transcript of the video.
Your body is made up of over 200 bones, a few trillion microbes, and as many as 37 trillion cells. And while death is often thought of as the end of the line for your self, your body still has a long way to go.
It doesn’t take long before your body starts to lose what makes you you. Just a few minutes after death, one of the first things to go is your brain. You see, when your heart stops beating, it halts blood flow, which is supposed to transport oxygen to your organs and tissues. So without blood, the most active, oxygen-guzzling organs and tissues go first. And the results are…moist. Because the cells that make up those organs and tissues are 70% water. Without oxygen to keep them alive, the cells self-destruct, spilling all that fluid onto the coffin floor.
By that night, an even more troubling process begins in the gut. Your dying immune system can no longer contain the trillions of hungry microbes that normally help digest the food you eat. So they escape. First, they travel from the lower intestines through your tissues, veins, and arteries. Within hours, they reach your liver and gallbladder, which contain a yellow-green bile meant for breaking down fat when you’re alive. But after the microbes are through eating those organs, that bile starts to flood the body, staining it a yellow-green.
From about day two to four, the microbes are everywhere. And they’re producing toxic gases, like ammonia and hydrogen sulfide, which will expand and cause your body to not only bloat, but stink.
After three or four months, your yellow-green complexion has turned brownish-black because your blood vessels have deteriorated to the point that the iron inside them spills out, becoming brownish-black as it oxidizes. Also around this time, the molecular structures that hold your cells together break away, so your tissues collapse into a watery mush.
And in a little over a year, your cotton clothes disintegrate, as acidic body fluids and toxins break them down. Only the nylon seams and waistband survive. At this point, nothing dramatic happens for a while. But by a decade in, given enough moisture, the wet, low-oxygen environment sets off a chemical reaction that turns the fat in your thighs and butt to a soap-like substance called grave wax. On the other hand, drier conditions lead to mummification. That’s right, you can mummify naturally. No wrappings, chemicals, or intimidating instruments required. Because throughout this entire decomposition process, water is evaporating through the thin skin on your ears, nose, and eyelids, causing them to dry out and turn black, aka mummify.
By 50 years in, your tissues will have liquefied and disappeared, leaving behind mummified skin and tendons. Eventually these too will disintegrate, and after 80 years in that coffin, your bones will crack as the soft collagen inside them deteriorates, leaving nothing but the brittle mineral frame behind. But even that shell won’t last forever.
A century in, the last of your bones will have collapsed into dust. And only the most durable part of your body, your teeth, will remain. Teeth, grave wax, and some nylon threads.
22 Things You Didn’t Know You Could Compost
Composting is a way of utilizing microorganisms to break down and decompose organic matter. The unique benefits of composting include a reduction of waste needlessly going into landfills and the production of a free stable, organic soil amendment that can’t be beat. Many people compost their yard waste and kitchen scraps, but there are many other materials that are generally thrown away that could easily be converted into compost and given back to the soil instead and far stranger ways to compost than most people realize.
Hair and Nail Clippings
(images via: klauspost, madaise, dvdmerwe, recyclethis, aprillynn77, joeshlabotnik, nightrose, massimobarbieri, skychen)
Human hair is a rich source of nitrogen and can be added to a compost pile or bin. Likewise, fingernail and toenail clippings can also be composted if they are free from all nail polish. If you happen to use peanuts to keep your toes apart during a pedicure, you compost those as well. Some people claim that in addition to being great for the compost, human hair in the garden helps repel deer that can quickly demolish treasured plants.
Beer, Wine and Brewery Waste

As unlikely as it is that you would have any beer or wine going to waste, if you did, it could be added to the compost. Wine can also act as a compost “starter,” and spur the bacteria in the compost to get to work. If you brew your own beer or make wine, the waste products from these processes can also be beneficial to the composting process.
Vaccum Cleaner “Dirt”
(images via: dnamichaud)
When you sweep or vacuum your floor, sofa or keyboard, most of the “dirt” you pick up is usually comprised of crumbs, dust, hair and similar debris. Instead of emptying the dustpan or canister into a wastebasket, it can be put into your compost bin, barrel or pile. Any synthetic fibers that may be picked up will not decompose during the composting process, but they won’t hurt the compost either and can be sifted out later if you wish.
Cotton Balls and Cotton Swabs
(images via: afiler, sundazed)
Used cotton balls and cotton swabs can also be composted. To be sure that your cotton balls and swabs are suitable for composting, check the packaging to make sure they actually are made of cotton, rather than synthetic fibers. Cotton is a natural substance and makes a wonderful addition to compost, but if you use synthetic “cotton balls” for makeup application or in caring for an infant, they will not decompose in the compost bin.
Used Paper Towels, Tissues, Paper Napkins and Toilet Paper Rolls
(images via: nickgray, cr01, chanbliss, tudor, osde-info)
Paper products that you use every day and generally toss in the garbage could be composting in your backyard, rather than sitting in a landfill. These items, including the cardboard cores and packaging can ad bulk to your compost. If you have allergies and use a lot of tissues, they can all go in the compost. If you have a cold or other type of viral infection, it may be best to consult a medical professional before composting them. Composting used tissues is a controversial issue. While most cold and flu viruses do not survive for long outside the human body, the jury is still out on composting tissues used during an illness.
Dry Pet Food and Pet Hair
(images via: punkrockkitten, sparkyd, rsgranne)
If you have pets, you probably have a readily and continuously available supply of compostable materials at your disposal. Any dry pet food that might go to waste makes an excellent addition to compost and can kick start the process into high gear. You have surely noticed that your pet sheds a lot too, and all that pet hair can go into the compost as well. Alternatively, in the early spring, you may want to leave clumps of pet hair and dryer lint in bushes near your home to provide native birds with nesting materials.

When a flower bouquet has seen better days, it can still be put to good use. While no longer fit to provide fragrance or home decor, these dead flowers can complete the circle of life by becoming compost to feed the soil, which will in turn feed the next generation of blooms. Nothing lasts forever, but dead and dying cut flowers can live on by going through the composting process.
Seaweed and Kelp

If you live near a body of water, you can collect seaweed and kelp to add to your compost. Avid gardeners often use seaweed and kelp to nourish their plants, and by adding them to your compost you are increasing the nutritional value of your end product. Compost enthusiasts have been known to drive great distances to harvest these materials, all in the name of better compost.
Unpaid Bills and Shredded Paper

Junk mail, bills you don’t intend to pay, magazines and other waste paper can be shredded and added to your compost. Paper is an especially good ingredient during the spring and summer months when carbon-rich dried leaves may not be readily available. If you have a cat, he or she may be willing to do your paper shredding for you, otherwise you can shred it by hand or use a commercial paper shredder to speed up the decomposition.
Halloween Pumpkins and Bales of Straw

After Halloween, there is usually an abundance of jack-o-lanterns on the curb for trash pick-up. Pumpkins decompose fairly quickly and are an excellent source of nitrogen for compost. Fall decorations also often include bales of straw, which can also be used as a carbon-rich ingredient in the compost pile.

It is always sad when an animal is struck and killed by a vehicle. Even sadder is when they are allowed to remain in the road where they are repeatedly run over, or cause an accident as drivers attempt to avoid hitting them again. It may take a hardcore composter to stop and pick up roadkill, but if a compost pile is at least 3’x3’x3′ in size, small animals can be given an above ground burial and become part of the composting process. In agriculture, when a larger animal dies, there are often large-scale university or state composting programs available to dispose of the corpses.
Green burials for humans are also becoming more of a mainstream option. While human bodies are not composted in the traditional sense, green burials do not rely on concrete vaults or embalming chemicals. The bodies are simply placed in a biodegradable casket and buried in an area that remains as natural as possible.
With proper setup, composting is odour-free, yields rich soil and safely returns the poop to the earth. Popular home composting methods include:
- A compost pit — about one metre deep by one metre wide, with a cover.
- Dog poop compost bins — available at pet stores and garden centres.
- Vermicompost — create a separate worm bin from the red wrigglers that eat your organics.
- Digester — buried in your yard and works similar to a composter. Available at local stores or make your own.
Dog-waste compost should be kept separate from other compost and is best used on ornamental — not edible — gardens, and kept well away from streams, groundwater or vegetable and fruit crops. Avoid children coming in contact with dog poop compost due to risks of toxocariasis.
Do not flush any baggies — not even biodegradable bags! Scoop the poop directly into the toilet, empty the bags or wrap it in toilet paper before sending it down the pipes.
Compostable bags require the heat of a compost pile to break down. And beware of the word degradable (as opposed to biodegradable), which refers to formulated polythene. Polythene bags will fragment, not biodegrade, leaving tiny bits of plastic in the water.
Even bags labelled “flushable” will clog plumbing or the city sewer. Never deposit dog poop down the storm sewer either, as these often flow to our waterways (e.g., creeks and streams). On a septic system? Check with the installer or manufacturer.
3. Green bins
Municipalities, including Toronto and the Region of Waterloo, encourage dog poop disposal in the green bin (in certified compostable plastic or paper bags, or wrapped in newspaper or paper towel). More municipalities are making this change. Check with your municipal waste management department or request the change.
4. Private dog-waste-collection services
This can be a good option for multi-unit residences (townhouses or apartments) where a group of dog owners share costs. Have you spotted red collection bins for dog waste? In Vancouver, it’s a private dog-waste-collection company in action. Poop goes to the sewage-treatment plant.
Making compost for your garden
Making your own compost is getting more popular, due to the increasingly green-conscious society. Home-made garden compost contains lots of nutrients that plants love – such as nitrogen and carbon. When you add it to your garden soil, it will make improvement and make it even better for growing plants!
Composting your kitchen and garden waste will give you an environmentally-friendly source of organic matter – and it’s free! It will take about 4 months to produce compost that’s lovely and crumbly and ready for planting your flowers, fruit and vegetables.
Why is composting important?
Waste such as food and grass accounts for around 35% of household waste that ends up in a landfill, where it breaks down and creates the powerful greenhouse gas, methane. As well as improving the environment and freeing up space at your local landfill site, compost is extremely practical for gardeners.
Compost helps soils ability to retain moisture, improves soil fertility and the general health of plants. Compost is essentially an organic fertiliser, so you will have no need for chemicals…another important benefit!
How to make compost
You will need a compost bin, old dustbin or similar, with holes in the bottom and garden &/or kitchen plant waste. The worms and micro-organisms needed to break it down into compost will find you! You will also want to use a compost bin that prevents unwanted scavengers! The compost bin ideally needs to be 150-250 litres and should be easy to fill and empty.
You’ll need a sunny corner of your garden to put your bin (or you can build your own from recycled timber – look on the internet for ideas). It needs to be placed on the soil, as you want worms and other micro-organisms to come up through the soil to help, and for any liquid to drain away. It will also need a cover to keep the warmth in and the rain out.
This is the most important part! You’ll need to keep adding equal amounts of nitrogen-rich green waste (grass clippings, green leaves, weeds, vegetable kitchen waste) and carbon-rich woody waste (prunings, wood chippings, torn-up paper, cardboard, straw or dead leaves).
For every wheelbarrow load or a bucketful of cut grass, you should mix in the same volume of sawdust, shredded cardboard or other woody waste. Avoid meat, fat and cooked food otherwise, you’ll just attract foxes, rats and other vermin; also worms don’t really like an excess of citrus remains.
Any large pieces of material should be cut into smaller pieces or even shredded; the smaller the pieces, the quicker they will rot down.
Composting is a biochemical process whereby organic matter is decomposed by naturally-occurring micro-organisms. Keep the compost heap moist, warm (wrap with a piece of old carpet in winter) and aerated, as these are the conditions that worms and micro-organisms love. Turn your heap occasionally with a garden fork to let the air in, making sure that you mix all the outside ingredients to the inside.
If you find that your compost isn’t rotting down quickly enough – it’s always slower in winter – then add a compost accelerator.
When the mixture is brown and crumbly and smells a bit like damp wood, then you’re ready to use in the garden!
