Androgenetic
alopecia is a common form of hair loss in both men and women. In men, this
condition is also known as male-pattern baldness. Hair lost in a well-defined
pattern, beginning above both temples. Over time, the hair line recedes to form
a characteristic ‘M’ shape. Hair thins, and lost at the top of the head,
often progressing or complete baldness. It is a combination of hormones, and
genetic predisposition. A similar type of hair loss in women, female pattern
hair loss, results in thinning hair on the mid-frontal area of the scalp and is
generally less severe than occurs in males.
Etiology
Male-pattern
hair loss is an inherited condition, caused by a genetically determined
sensitivity to the effects of dihydrotestosterone, DHT, in some areas of the
scalp.
Pathogenesis
Polygenic
inheritance; variable penetrance. The hair follicles have increased numerous
androgen receptors as well as increased activity of 5-a-reductase type II,
leading to increased androgen sensitivity. Dihydrotestosterone also causes
shift to telogen hairs. In female pattern hair loss, there may be an increased
sensitivity to circulating androgen, as androgen levels are usually within
normal limits.
Clinical
features
Thinning of
hair without scalp disease. Male pattern and Female pattern.
The presence
of whisker hair at the temples may the first sign of this condition. The
follicles produce finer, shorter and lighter or virtually unpigmented terminal
hair, until a complete cessation of terminal hair growth results. Miniaturized
hairs become increasingly evident, replacing coarser intermediate or terminal
hair.
In males, the
replacement of terminal by smaller hair occurs in a distinctive pattern that
spares the posterior and lateral scalp margins, even in the most advanced cases
and in old age. There is a recession of the anterior and bitemporal hairline,
so that the forehead becomes high, followed by balding of the vertex. The loss
is thus more noticeable at the vertex and in the bitemporal regions of the
scalp. The rate of hair loss varies from person to person, depending on the
hereditary factors.
It has been
recently suggested that bald men are more likely to have a heart attack and prostate
cancer than with a full head of hair.
HOMEOPATHY
MEDICINES
Homoeopathy today is a
growing system and is being practiced all over the world. Its strength lies in
its evident effectiveness as it takes a holistic approach towards the sick
individual through promotion of inner balance at mental, emotional, spiritual
and physical levels. When Androgenetic alopecia is concerned there are many
effective medicines are available in Homoeopathy, but the selection depends
upon the individuality of the patient, considering the mental and physical
symptoms.
