Female pattern hair loss is a common condition characterized by a diffuse reduction in hair density over the crown and frontal scalp with retention of the frontal hairline.
FPHL is now the preferred term for androgenic alopecia (AGA) in women
the prevalence and severity increases with advancing age
prevalence in the UK and USA studies in Caucasian women show similar frequencies, increasing from 3% to 6% in women aged under 30 years to 29 to 42% in women aged 70 and over
oriental women have a lower frequency of androgenetic alopecia than women of European origin
The exact aetiology of female pattern hair loss (FPHL) is not known
there is a progressive miniaturization of hairs, resulting in loss of hair density and widening of the midline part clinically
in contrast to male-pattern hair loss, the androgenic nature of FPHL is not clear and women often have normal hormonal profiles and no other signs of androgenization
hypothesized that FPHL has a polygenetic mode of transmission
it is thought that early- and late-onset female AGA are genetically distinct
Most women present with a history of gradual thinning of scalp hair, often over a period of several years
hair loss can start at any time between early teens and late middle age – however hair loss may precede pubarche and menarche
frequently a history of excessive hair shedding, but unlike telogen effluvium, hair thinning is usually noticed from the outset
Pattern of hair loss
examination of the scalp shows three different patterns:
diffuse thinning of the crown region with preservation of the frontal hairline – two scales can be used to describe this pattern
the commonly used 3-point Ludwig scale
the 5-point Sinclair scale
thinning and widening of the central part of the scalp with breach of frontal hairline (christmas tree pattern) – assessed by Olsen scale
thinning associated with bitemporal recession – Hamilton-Norwood type
in some women the hair loss may affect a quite small area of the frontal scalp whereas in others the entire scalp is involved, including the parietal and occipital regions
although many women develop a minor degree of postpubertal recession at the temples whether or not they have diffuse hair loss
Diagnosis
usually straightforward but other causes of diffuse hair loss may need to be excluded, particularly when the hair loss progresses rapidly
occasionally, systemic lupus erythematosus can also present in this way
in alopecia areata there may be hair loss in other sites
hypothyroidism is also in the differential
Management
antiandrogens and topical minoxidil have been used in the management of this condition
