Death is often seen as a relentless process, capable of transforming organic matter into mere memory.
However, there are cases that challenge this notion, such as the notable example of Salvador Dali, whose iconic mustache remained untouched 28 years after his death.

How is it possible that elements like hair It is nails overcome even death? In part, it lies in the nature of these structures, composed of keratin, a notoriously resistant component.
It is present in hair and nails and gives them surprising durability, making these elements the last traces to surrender to time after burial.
Ricardo Romiti, specialist in the Dermatology department of the Hospital das Clínicas of the University of São Paulo, clarifies that both nails and hair are not considered living tissues of the body human.
These structures are predominantly composed of keratin and contain minimal amounts of water in their structure. composition, characteristics that contribute significantly to the remarkable resistance to degradation Natural.
The process of decomposition, as exemplified by mummies, can span decades or even centuries.
However, it is important to note that the durability of these structures after death may vary depending on the circumstances under which the body is discarded.
The degradation of nails and hair is directly influenced by the environment where the corpse was placed, as Ricardo Romiti explains.

Having direct contact with the soil or water tends to significantly accelerate this process, since such environments provide favorable conditions for the proliferation of fungi and bacteria that feed on keratin, the main component of nails and hair.
Therefore, the more isolated the corpse is, the longer the nails and hair will survive after death.
Romiti also notes that the amount of water present in organs plays a crucial role in how quickly postmortem degradation occurs.
Organs rich in water, such as the circulatory system, are the first to suffer from decomposition, while the heart, lungs and intestine are also among the first to decompose.
Understanding the environmental and biological factors that affect decomposition helps clarify why some body parts, such as nails and hair, can persist longer.
