Androgenetic alopecia is the hereditary form of baldness that affects
50 percent of men, and some women after 40. Female hair loss usually
starts after menopause although it can begin earlier. The main reason
for this is that estrogen levels decline. Hormonal changes cause hair
to thin.
It is comforting to note that other than androgenetic alopecia, the
most common cause of hair loss in women, is a result of metabolic and
hormonal changes. Thus, the hair loss is usually temporary. Also,
unlike men, women rarely become totally bald. However, what females
generally experience is the thinning of their hair.
For example, in the case of pregnancy, hair loss is temporary and
should stop about 6 months after birth. When a woman is pregnant, a
large amount of oestrogen is produced causing the hair follicles to go
into their growth phase. Once the baby is born, the woman's hormonal
balance is restored. The reverse now happens with the hair follicles
going into a hair loss phase.
While nothing much can be done to prevent hair loss during this
period, applying hair tonic to hasten hair re-growth can be a helpful
solution.
Crash diets leading to rapid weight loss over a short period of time
prompts excessive hair loss.
Physical and emotional stress can cause hair loss but this usually
only occurs after
