Hair,
hair - everywhere hair!
Hairhow to grow it and how to permanently stop it from growingtranslates
into a multi-billion dollar industry growing by leaps and bounds.
Interest in hair removal has never been higher. Whether this interest
can be attributed to society's current description of beauty, the
mass media assault for new technologies or people just getting hairier,
consumers are actively searching for the perfect hair removal solution.
Historically, hair removal products, equipment and services have
been primarily targeted towards females. Not all societies have
a hairless model of feminine beauty but many, including the United
States, have long held the standard that "hairy body parts"
are masculine and unappealing on a female body.
Hirsutism
hypertrichosis and hyperandrogenism
What is hirsutism? Hirsutism is the
medical term for excess body or facial hair in women. It can easily
be described as a male hair growth pattern or distribution on a
female body. Hirsutism is considered a disease by many medical
authorities and can be the result of a serious underlying
disorder that can be easily be ruled out with a medical history
and some simple blood tests. Hirsutism is usually caused by an increased
production of a group of hormones called androgens ("male hormones")
or an increased sensitivity of the skin to these hormones. Androgen
disorders affect between 5% to 10% of all women. Women with hirsutism
have an increased production rate of testosterone and androstenedione.
What is hypertrichosis? Hypertrichosis
is usually described as an excessive quantity of hair in a normal
location on one's body compared to others of the same sex, age,
and ethnic background. Men usually have hair on their chest. If
a man had a lot of hair on his chest, it would be called hypertrichosis.
But a woman with a full beard would be called hirsute. Women do
not normally have a beard. When a woman has a lot of hair on the
calf of the leg, it would not be called hirsutism but hypertrichosis.
Women normally have hair on their calves. Women who have a few chin
hairs and a few upper lip hairs would be called hypertrichotic but
not hirsute.
What is hyperandrogenism? Hyperandrogenism
is increased levels of male hormone production in women. The causes
of hyperandrogenism and hirsutism in women are as follows:
- Chronic anovulation - i.e.
polycystic ovarian syndrome
- Idiopathic hirsutism - excess
hair growth with normal menstrual cycles and normal androgen (male
hormone) levels
- Late onset congenital adrenal
hyperplasia - an inherited disorder of hormone metabolism that
causes increased hair growth in women after puberty
- Ovarian tumors - a rare cause
of hirsutism
- Adrenal causes - more rare
cause of hirsutism
- Pregnancy related - also
rare, e.g. luteoma of pregnancy (tumor derived from the corpus
luteum cells of the ovary)
- Drugs - some drugs can cause
excess hair growth in women
The most commonly seen clinical problem is irregular menstrual cycles
(anovulation), onset of hirsutism in the teens or early 20s, and gradually
worsening excess hair growth. These are the findings associated with
the condition known as polycystic ovarian syndrome.
Treatments for hyperandrogenism range from oral contraceptives
to Spironolactone to Flutamide. Testosterone (T) levels should be
tested and a tumor workup should be done if the total testosterone
is over 200 ng/dl. Additional tests such as Dehydroepiandrosterone
sulfate (DHEAS), 17-hydroxyprogesterone for CAH, prolactin, T4,
TSH, breast exam, and an endometrial biopsy may be indicated.
For most women, the tendency towards hirsutism is inherited. Excess
hair growth may be present in both the female and male family members.
Hirsutism usually begins around puberty, but mild hirsutism can
start at any age. Most women gradually develop more facial or body
hair with age. In the recent past, unwanted hair has been considered
a "taboo" topic of conversation and therefore, many affected
women did not realize how common their problem was. At least 25%
and as much as 85% of normal middle-aged women remove unwanted facial
and body hair, although few of these women are termed hirsute.
