Female pattern baldness usually begins about age 30, becomes noticeable around age 40, and may be even more noticeable after menopause. It is thought that about 15% of American women have such hair loss; around 30% of affected Caucasian females are affected before menopause. There are four main reasons to cause of hair loss in women :
Genetic Cause of Hair Loss
in Women -
Diffuse Hair Loss
The most common type of hair loss in women occurs in
a diffuse pattern. Diffuse hair loss is most often
hereditary, but it can also be caused by underlying
medical conditions, medications, and other factors.
Female pattern baldness, or androgenetic alopecia, is estimated to occur in 15% or less of American women. The chemical process in the body is similar, in that hormones and dehydrotestosterone (DHT) combine to cause hair follicles to shut down.
Even though the chemical process is the same, the appearance of the hair loss in females is generally different, with women experiencing general thinning of hair rather than the bald spots or pronounced receding hairline so common in men.

Medical Causes of Hair Loss
in Women
Diffuse & Localized
Women’s hair seems to be particularly sensitive to
underlying medical conditions. Since "systemic"
problems often cause a diffuse type of hair loss
pattern that can be confused with genetic balding,
it is important that women with undiagnosed hair
loss, be properly evaluated. Medical conditions that
produce a diffuse pattern include:
Hormones : Women experience far more hormonal issues than men
do, and at a much greater frequency. Pregnancy, childbirth and
menopause are all conditions unique to women that can affect the
amount and permanence of hair loss and cause balding.
Illness / Surgery : Many common illnesses can cause
female hair loss, such as diabetes and thyroid over- or
under-activity, as can conditions that put the body under stress
such as high fevers or major surgery.
Historical
diseases and
possible hair loss etiologies
Medication : A relatively large number of drugs can cause telogen effluvium, a condition where hair is shifted into a resting stage and then several months later shed. Fortunately, this shedding is reversible if the medication is stopped, but the reaction can be confused with genetic female hair loss if not properly diagnosed. The drugs that can cause diffuse hair loss in female including :
- Blood thinners (anti-coagulants), such as warfarin and heparin
- Seizure medication, most commonly dilantin
- Medication for gout, colchicines and alopurinol (Xyloprim)
- Blood pressure medication, particularly the b-blockers (such as Inderal) or diuretics
- Anti-inflammatory drugs such as prednisone
- Medications that lower cholesterol and other lipids
- Mood altering drugs - lithium, tri-cyclics, Elavil, Prozac
- Chemotherapy
- Thyroid medications
- Oral contraceptive agents, particularly those high in progestins
-
Misc : diet pills, high doses of Vitamin A, street drugs
(cocaine)
List
for medication drugs cause hair loss
Other Causes : Anemia, anorexia, bulimia, excess vitamin A, fungal infections, and zinc or fatty acid deficiency can also be the cause of hair loss in women.
