Do you usually find a lot of hair on your pillow or brush? If yes, beware! You may be missing more hair than normal. In this article, you will learn the main causes that can lead to female hair loss.

You might already know that losing 50 to 100 hairs per day is very normal. But according to Harvard Medical School, one in three women lose more than that. Several factors can be responsible for the increasing hair loss, including genetics, hormones, medications, stress and even our lifestyle and daily care with hair.

The good news is that many of these causes can be treated and your hair can regain normal growth.

Androgenetic Alopecia

You may have heard of male pattern baldness, which is much more common than female pattern baldness. However, more than 21 million women in the United States are born with the female version of this condition, called Androgenetic Alopecia, the leading cause of hair loss in both sexes. This is a hereditary, genetically determined form of hair loss that begins to develop in adolescence when hormone production begins.
In men, hair tends to get thin in the crown and in the frontal region and can lead to total baldness. In women, it usually starts at the top of the head and progressively the hair becomes thin, leaving the scalp exposed. However, women rarely lose all their hair; instead, their hair tends to become scarce, and the scalp can be visible. Symptoms usually begin to appear more strongly after age 40 and continue throughout your life.
In this case, the best is to look for a dermatologist or medical trichologist, who can prescribe medicine to help regain hair loss. According to the International Journal of Women’s Dermatology, several hormonal treatments may help: Contraceptives, Spironolactone, Cyproterone, and Finasteride.


Many women after giving birth find their hair falling a lot. This is because of the level of estrogen that sinks after the baby is born. Hair usually reappears when hormones stabilize.

Menopause is another hormonal trigger for temporary hair loss. Again, your hair will grow back, but may not be as full as before.

Medical Conditions

Hair loss can be a sign of another disease, or it can happen after an illness and its treatments. For example:

  • Thyroid diseases.
  • Anemia (low iron content in the blood).
  • Ringworm, which can spread from person to person and can cause baldness.
  • Infections or high fever.
  • Radiation and chemotherapy for cancer.
  • An autoimmune disease called Alopecia Areata: Your own body attacks your hair, resulting in circular locks without hair.
  • Cicatricial alopecia, when hair begins to fall from the middle of the scalp and spreads, leaving parts of the scalp smooth and shiny and can cause scars on the affected areas.
  • Diabetes.
  • Birth control pills, blood thinners, and some steroids.
  • Medications that treat arthritis, depression, gout, heart problems, and high blood pressure.

In these cases, most of the time the hair loss is temporary and grows back.



Stress is a major disorder of modern life. It can be triggered by a death in the family, a divorce or unemployment and cost a piece of your hair. A sudden shock or illness can lead to a condition called Telogen Effluvium, which is characterized by increased daily hair loss. It is usually noticed when a large amount of your hair falls while you comb it or wash it.

Stress can also lead to a behavioral disorder that generates an uncontrollable desire to pull hair from the head, eyebrows, eyelashes and other places. It is called Trichotillomania, and this is an unconscious way of relieving tension, frustration, and different uncomfortable feelings.

Diet and Nutrition

In general, the reason is the lack of nutrients or excess food supplements.

Loss of weight (usually more than 10 kilos) in a short time. Hair loss usually appears 3 to 6 months after losing weight, and the hair grows back again without any help.

  • Lack of iron. Almost one in 10 women aged 20 to 49 suffers from
    anemia due to iron deficiency. This is the most common type of
    anemia, which is an easily solvable cause of hair loss. Have a blood test to determine for certain if you have this kind of anemia.
  • Lak of proteins and other nutrients. Many people often lose
    hair during some diet. Usually the hair starts to fall out after about 2 to 5 months of low protein level in the body.
  • Vitamin A in excess (usually with supplements). Believe me, too much vitamin can hurt you too! Too much Vitamin A causes hair loss, so the recommended daily dose is 5000 IU.
  • Anorexia (severely restricting food) and Bulimia (vomiting on purpose after eating)

Dramatic Weight Loss

Very fast weight loss is a form of physical trauma that can result in hair loss. This can happen even if weight loss is ultimately good for you.

It’s possible that weight loss itself is forcing you to not eating right resulting in vitamin or mineral deficiencies.

Hair loss along with the aggressive weight loss, may also be a sign of a disturbance such as anorexia or bulimia.

Genetic Factor

Yes genetic does exist! Bald grandparents, parents and children are not mere coincidence. Genetic factors weigh inheritance also on the hair. My Father is bald, will I be for sure?
The answer is no.


It is not uncommon to see hair loss or weakening of the hair in men and women entering their 50’s and 60’s. Experts are unsure why this happens.

Hair Care Habits

The habit of using your hair in a ponytail can cause damage to the hair, such as breakage, dryness and reduced growth. Other habits that can lead to hair loss problems include:

  • The high temperature of a hairdryer.
  • Some chemicals
  • Hair pulled with clips, bands or pins
  • Excessive washing or brushing, especially when your hair is wet


Those cuts, or better, those curly hairs that mostly followers of Bob Marley use can cause hair loss. This can happen because it impairs the cleansing and oxygenation of the scalp


Your doctor can focus on what is behind your hair loss, performing different tests that will likely begin with a physical examination and looking through your family and medical history. In some cases, several tests are necessary until the cause is identified. Those test might include:

  • Blood tests to find problems such as iron deficiency and thyroid disease.
  • Hair shaft examination: Using a light microscope, your doctor will check for any clutter in the shaft of your hair.
  • Traction test: pulling a piece of your hair to get a rough idea of ​​how much of your hair is being lost.
  • Scalp examination: Your doctor will check for any infection and see where the hair is falling. This can help find out if you have genetic hair loss.
  • Biopsy: Skin scalp samples are scraped, collected and sent to a laboratory for testing. This can give your doctor a more detailed view of the scalp and hair root.
