About 15 percent of women have hair loss, also known as Alopecia or pattern baldness. Hair Loss usually develops gradually and may be patchy or diffuse (all over). In women, androgenic alopecia is probably the most common.
Loss of hair is more than a minor cosmetic problem. It has to potential to make you feel vulnerable (naked), and can cause unfavorable changes in how you feel about yourself.
Roughly 100 hairs are lost from your head every day. The average scalp contains about 100,000 hairs. Hair grows from its follicle at an average rate of about 1/2 inch per month. Each hair grows for 2 to 6 years, then rests, and then falls out. A new hair soon begins growing in its place. At any one time, about 85% of the hair is growing and 15% is resting.
Loss of hair or baldness occurs when hair falls out but new hair does not grow in its place.
Causes of Hair Loss in Women
The cause of the failure to grow new hair is not well understood, but in the case of women with PCOS (polycystic ovarian syndrome), excessively high levels of androgens (male hormones) are thought to be primarily responsible.
A male hormone called dihydrotestosterone (DHT), which is converted from testosterone, binds to sites on hair follicles and appears to make the follicles go into their “resting” phase sooner, which in turn starts to cause the hairs produced by those follicles to become thinner and thinner with each growth cycle.
Women with high or increasing levels of androgens, such as women with PCOS or who are menopausal, may find that the hair on the head is thinned, while facial hair is coarser. Although new hair is not produced, the follicles remain alive, suggesting the possibility of new hair growth.
It appears that sex hormone imbalances or fluctuations are responsible for most female hair loss, including those who have PCOS, recent pregnancy, menopause, postmenopausal trauma, or birth control side effects.
Androgenic alopecia is hair loss due to a male hormone imbalance, and is probably the most common cause for hair thinning and loss in PCOS women.
However, androgenic alopecia is not to be confused with estrogenic alopecia, which is due to a fall in estrogens.
In contrast to testosterone, estrogen helps hair grow faster and stay on the head longer, resulting in thicker hair. This is the reason women’s hair gets fuller during pregnancy when estrogen levels are quite high, then sheds several weeks after the baby is born. Estrogen-deficiency alopecia generally starts around menopause. Because estrogen levels start to fall before periods stop, this form of female hair loss can be the first sign of approaching menopause. But sometimes the alopecia does begin until a few months or even a few years after menstruation has ended. Not all women get noticeable alopecia after menopause but most have at least mild thinning.
Many PCOS women also have thyroid problems, usually hypothyroidism (low thyroid function). Not only does hypothyroidism contribute to weight problems, it can also contribute to hair thinning. Some women with PCOS have both an excessively high level of testosterone and an underactive thyroid. It’s not uncommon to have multiple factors involved in female hair loss.
Insidious poisoning with heavy metals such as lead, mercury or cadmium can show up as hair thinning. Sources are everywhere in the environment. Be particularly interested in this if you have lived near a mining site, or worked or lived with someone who works in an industry that uses metals. If you smoke tobacco, you get a lot of cadmium. A hair analysis can indicate abnormally high levels of these heavy metal toxins. If you want a hair analysis, or have high levels of metals showing up in a hair analysis, consult with aNaturopathic Physician or a Registered Medical Doctor.

The typical pattern of female pattern baldness is different from that of male pattern baldness. The hair thins all over the head, but the frontal hairline is maintained. There may be a moderate loss of hair on the crown, but this rarely progresses to total or near baldness as it may in men.
Main Symptoms of Female Hair Loss
1) Thinning of hair over the entire head
2) Mild to moderate hair loss at the crown or hairline.
Female pattern baldness in the advanced stages can be severe thinning of the hair and may lead to be permanent Hair Loss if appropriate treatments are not used.
Natural Hair Loss Remedies
Saw Palmettois a natural substance that inhibits the action of testosterone, the hormone primarily responsible for female hair loss.
Frequent shampooing is advised if you have an oily scalp with thinning hair. These surface oils contain high levels of testosterone, which can re-renter the skin and affect the hair follicle.
A deficiency in essential fatty acids may result in dry, brittle hair, and possibly hair thinning or loss. The omega-3 fatty acids are especially important, such as those found infish-oil.
B-vitamin deficiencies are common. Some people, especially people who are blood type A, do not absorb B vitamins very well from food. In particular a vitamin in the B family called biotin is crucial for proper hair and nail growth. In high doses, 5-8 grams daily (5000-8000 mg) of biotin can be effective in restoring head-hair growth, with no known side-effects. Some specialty shampoos feature biotin for this reason.
A deficiency in manganese or other minerals may contribute to hair loss, so you’ll want to make sure you’re eating a very healthy diet or taking a multi-vitamin and mineral supplement.
Other Female Hair Loss Treatments
Hair transplants consist of removal of tiny plugs of hair from areas where the hair is continuing to grow and placing them in areas that are balding. This can cause minor scarring in the donor areas and carries a modest risk for skin infection. The procedure usually requires multiple transplantation sessions and may be expensive. Results, however, are often good and permanent.
Suturing of hair pieces to the scalp is not recommended as it can result in scars, infections, and abscess of the scalp. The use of hair implants made of artificial fibers was banned by the FDA because of the high rate of infection.
Hair weaving, hairpieces, or change of hairstyle may disguise female hair loss and improve cosmetic appearance.
