Telogen effluvium
Telogen effluvium is a phenomenon that
occurs after pregnancy, major surgery, drastic weight loss, or extreme
stress, in which you shed large amounts of hair every day, usually when
shampooing, styling, or brushing. It can also be a side effect of
certain medications, such as antidepressants, beta-blockers, and
nonsteroidal anti-inflammatory drugs. During telogen effluvium, hair
shifts faster than normal from its growing phase into the "resting"
phase before moving quickly into the shedding, or telogen, phase.
The symptoms: Women with telogen effluvium typically
notice hair loss 6 weeks to 3 months after a stressful event. At its
peak, you may lose handfuls of hair.
The tests: There are no tests for telogen effluvium,
but your doctor may ask you about recent life events and look for small
"club- shaped" bulbs on the fallen hair’s roots. The bulbs mean the
hair has gone through a complete cycle of growth, suggesting that the
cycle may have sped up due to stress.
What you can do: In some cases, such as pregnancy or
major surgery, you may have to bide your time until the hair loss
slows. If medication is the culprit, talk to your doctor about lowering
your dosage or switching drugs. If it’s stress-related, do your best to
reduce anxiety. Try these simple
tips for relieving stress and worrying.
Hereditary hair loss
Hair loss that is genetic is known as
androgenetic alopecia and, according to the American Academy of
Dermatology, is the most common cause of hair loss. The gene can be
inherited from either your mother's or father's side of the family,
though you're more likely to have it if both of your parents had hair
loss.
The symptoms: Women with this trait tend to develop
thinning at the hairline behind the bangs, says Pamela Jakubowicz, MD, a
dermatologist at Montefiore Medical Center in New York City. The
condition develops slowly and may start as early as your 20s. You may be
vulnerable if your mother also has this pattern of thinning. In some
cases, the hair loss may be diffuse, meaning it's spread across the
entire scalp.
The tests: Your dermatologist will examine the
pattern of hair loss to determine if it’s hereditary and may order blood
work to rule out other causes, Dr. Jakubowicz says. A biopsy of your
scalp is sometimes done to see if the hair follicles have been replaced
with miniaturized follicles, a surefire sign of hereditary hair loss.
What you can do: Slow the hair loss by applying
minoxidil (Rogaine) to the scalp twice a day. The drug works on both
women and men, although women should use a lower-strength formula to
prevent unnecessary side effects. Women should not use minoxidil if they
are pregnant or nursing. Men may be treated with finasteride
(Propecia), an oral medication.
