What does alopecia mean?
Alopecia is the medical term for hair loss from the scalp or elsewhere on the body. It covers a spectrum of conditions: androgenetic alopecia, the common hereditary thinning often called male- or female-pattern baldness; alopecia areata, an autoimmune disorder producing sudden round patches of baldness; and rarer forms such as alopecia totalis and universalis, which involve loss of all scalp or body hair. Causes range from genetics and hormones to immune dysfunction, stress, and certain treatments such as chemotherapy. Though chiefly used by doctors and dermatologists, the word appears frequently in everyday conversation and media coverage of hair loss, and public figures who speak openly about living with alopecia have made it increasingly familiar. Its origin lies in the Greek word for fox, reflecting an old belief linking the animal's mangy coat to baldness.
nounLoss of hair from the scalp or other parts of the body, occurring in various forms that range from small bald patches to complete loss of body hair.
- Hair loss from the scalp or body generally, encompassing all clinical types (areata, androgenetic, totalis, universalis).
- Specifically, patchy autoimmune hair loss known as alopecia areata.
"After months of unexplained shedding, she was diagnosed with alopecia areata."
"The dermatologist explained that his thinning crown was classic androgenetic alopecia."
"Living with alopecia, she chose to embrace her baldness rather than wear a wig."
Rare outside medical writing, where it denotes the various types of the condition collectively; everyday usage treats alopecia as an uncountable condition name.
"The textbook devotes a chapter to the different alopecias and their treatments."
The word 'alopecia' literally traces back to the ancient Greek word for fox — because foxes were thought to suffer from mange, making them the original poster animals for hair loss.

Etymology of alopecia
Alopecia comes from the Latin 'alopecia', borrowed from Greek 'alōpekía', a term derived from 'alōpēx', the Greek word for fox. The connection arose because foxes were observed to lose fur through mange, so the fox became associated with baldness in ancient medical writing. The term entered English medical usage in the early modern period and remains the standard clinical name for hair loss today.
How alopecia is actually used
Alopecia is primarily a medical term but is widely used in everyday discussion of hair loss. It carries little inherent stigma as a word, though the condition it names can be emotionally significant for those affected. Clinicians often specify the subtype (areata, totalis, universalis, androgenetic) when using the term.
