Types of Alopecia in Women

  • Female pattern hair loss (FPHL) is the most common form of alopecia in women, affecting approximately one-third of adult Caucasian women 1.
  • FPHL is characterized by diffuse alopecia over the mid-frontal scalp, resulting from nonuniform hair follicle miniaturization within follicular units 1.
  • Androgenetic alopecia, also known as female androgenetic alopecia (FAGA), is a type of alopecia that is caused by androgens in genetically susceptible women 2, 3.

Age of Onset

  • The thinning of hair in women with androgenetic alopecia typically begins between the ages of 12 and 40 years 3.
  • FPHL can occur at any age, but it is most common in women under 40 years of age 4, 1.

Diagnosis and Treatment

  • The diagnosis of FPHL is typically made by clinical history, clinical examination, and laboratory tests, including androgenic determinations 2.
  • Treatment options for FPHL include topical minoxidil, oral antiandrogen therapies, and hair transplantation 2, 4, 1.
  • Early diagnosis and initiation of treatment are desirable, as treatments are more effective in preventing the progression of hair loss than stimulating regrowth 4.
