Final answer:
Canities is the technical term referring to the graying or whitening of hair, a process resulting from decreased melanin production.
Step-by-step explanation:
The term Canities is a technical term used in Biology, specifically when discussing human physiology and aging. It refers to the phenomenon of grey hair or white hair. This process is a natural occurrence as we age and is caused by a reduction in the production of melanin, the pigment responsible for hair color. As melanin levels lower, the hair gradually shifts from its natural color, be it black, brown, or otherwise, to grey, and eventually white.
