Men and women experience hair loss for similar reasons.
Hormonal Changes
Men, unfortunately, experience a more dramatic, specific pattern of
hair loss commonly termed "Male Pattern Baldness." This loss is
caused by dihydrotestosterone (DHT).
DHT is a hormone linked with testosterone. DHT binds to receptor sites
on the scalp and hair follicles, interacting and interrupting the normal chain
of events involved in continual healthy hair growth.
Woman,
experience many hormonal changes throughout their lives which can lead to hair
loss. In general, women may lose hair after a pregnancy, or during menopause.
But it is not limited to just these. Any number of hormonal imbalances can
trigger hair loss in women.
Hormonal changes in both men and women can cause hair loss by
directly affecting the cells responsible for hair growth or by affecting the
level of nutrients and blood flow to the follicle. The hair follicle cannot
maintain a healthy growth cycle without proper nutrients and may eventually
fall out and die.
Stress
Stress affects the hormone balance and it
will transmit signals to the hair follicles.
The hair follicles then undergo a resting stage. Usually it occurs 3
months after the stressful event has occured and it may take 3 months after the
stress period has ended for the hair growth to resume. If the stress continues
or is repeated the onset of genetic hair loss may worsen existing hair loss.
Supplements
A series of other factors can cause hair
loss, including diets, the use of certain bodybuilding supplements, and
environmental factors.
Hairstyle
Chemicals used for dying, tinting,
bleaching, straightening or perms can cause hair to become damaged and break
off if they are overused or used incorrectly. Also using excessive heat either
by use of your normal hairdryer, straightners or curling tongs can lead to hair
thinning. Overstating and excessive
brushing also can cause hair to fall out if the hair shaft becomes damaged.
