==Overview==
==[[Alopecia overview|Overview]]==
'''Alopecia''' is the resulting condition from the loss of hair, which is termed ''effluvium.'' It should be distinguished from [[baldness]], which is the ''lack'' of hair, including contexts where that absence is intentional.  (In some cases the terms are used interchangeably, and in some conditions such as [[trichotillomania]], where the loss of the hair is due to intentional acts, but the motive for that act is defined as a medical condition, it can be difficult to determine whether the label "alopecia" is appropriate.)


Alopecia is characterized by scarring or non-scarring. Scarring alopecia is caused by numerous dermatologic factors, including glabrous skin (non-hairy), and is very difficult to diagnose and manage.  Non-scarring alopecia is characterized by the absence of visible inflammation of the skin involved.
