    Yes it does. 

    And it’s on’s list of “22 Things You Didn’t Know You Could Compost” also. Apparently, hair is rich in nitrogen and great for composting.

    Human hair definitely decomposes (remember, visible hair is protein that is already dead – this is why cutting your hair doesn’t hurt), though depending on  conditions (temperature, moisture) the rate of decomposition varies. I’ve seen one year offered as a relative average. Of course, if preserved in the right conditions, hair can maintain itself for thousands of years The Tarim or red-haired mummies of China, circa 1800 BC and the Tollund Man (or peat bog man, 400 BC) are two examples.
