Does hair rot away

Hair itself does not "rot" in the traditional sense because it is primarily made of keratin, a protein that is resistant to decay. However, hair can become damaged, break, or fall out due to various factors like environmental conditions, chemical treatments, or health issues. When hair is removed from the body, it can eventually degrade over time due to exposure to moisture, microorganisms, and other environmental factors. In summary, while hair can deteriorate when not on the scalp, it doesn't rot like organic matter.
