Hair Loss Definition & Overview

Definition

Alopecia refers to hair loss in areas of skin that normally have hair. There are two forms of alopecia scarring and non-scarring.

Scarring is the loss of hair follicles. This form causes permanent hair loss. The most prevalent forms of scarring alopecia are:

  • Cutaneous lupus erythematous
  • Central centrifugal cicatricial alopecia
  • Fungal kerions

In the case of non-scarring, the hair shaft is gone, but the follicles are still present. It often is reversible. It can also develop into the scarring type. Non-scarring types include:

  • Androgenetic (hereditary) alopecia
  • Telogen effluvium
  • Alopecia areata is an autoimmune process; the cause is not known
