Sudden Hair Loss in Women: Causes and Stories

Sudden Hair Loss in Women Patients is a growing problem, we often associate hair loss with men, but it can be equally prominent in many females, and lead to severe anxiety and stress. You may notice patchy hair loss, or patterned type of shedding similar to male-pattern balding. There are different causes from stress, to Autoimmune conditions. We will discuss the causes and provide some patient stories from different women.

What is a Pull Test?

A doctor will grasp an area of hairs and gently pull on the hair with the thumb and index fingers. If this test produces more than 3 - 5 hairs it would be considered a Positive Pull-test. This may indicate a patient has androgenetic alopecia, alopecia areata or even scarring alopecia, however more tests would need to be done to confirm this diagnosis.

Angrogenetic Alopecia:

This is one of the more common causes of hair-loss, even though it is more commonly seen in men, women can also be affected. It is also known as Male-pattern balding and over half of women over 80 will be affected. Angrogenetic Alopecia is less common in asian's, and African Americans and is most common in white men.

This pattern of hair loss in women is steady thinning over the crown which slowly widens as shown in the image below. Eventually, the entire top part of the scalp may be affected. There are different low cost products including hair building fibres, scalp thickeners, hair pieces which can help camouflage hair loss.

Medical treatment is also possible, with 5% Minoxidil being shown to be effective. Finastaride is a synthetic steroid that reduces DHT production and limits hair loss. Female pattern baldness can be very stressing for women, and studies have shown that women become extremely upset by hair loss as compared to men.

Studies have shown that baldness in Women can also be linked to having your father being bald, as well as having a mother who carried a similar gene, would give you a much higher risk of developing baldness.

Hypothyroidism and Hyperthyroidism

There are conditions which affect the thyroid, namely Hypothyroidism (underactive thyroid) which may result in hair loss and dryness. Another cause may be Hyperthyroidism (overactive thyroid) which can also cause hair thinning. It is important to visit your doctor so that they can measure the amount of
  • thyroxine
  • and TSH in your blood.

    Fortunately, once the thyroid hormone levels are corrected - hair growth should return to normal

    Telogen Effluvium:

    Telogen Effluvium would cause Hair loss all over the scalp, so the pull test would, so the pull-test would be positive in many areas. It is often caused by stress, or a serious illness or surgery. Once the cause of the stress is eliminated hair should grow back. TE can also be caused by low iron, thyroid problems, taking certain medications. It is advisable to check with your doctor if you suspect you have large amounts of hair loss.

    Anagen Effluvium:

    This is one cause of hair loss, that affects both men and women. It is mainly linked to a side effect of chemotherapy but is is also caused by toxic chemicals and results in sudden and severe hair loss. Anagen Effluvium can also cause hair thinning in other areas like eyebrows, eyelashes and body hair. It is often possible to diagnose this condition by looking at the hair under a microscope which shows the end's of the hair tapered, and narrow.

    Since chemotherapy uses strong drugs like daunorubicin, doxorubicin, and methotrexate, it can cause toxicity in the hair follicles, and increased loss within 3 weeks of chemotheraphy. It is important to realize that hair will grow within a few months of ending chemotherapy. Minoxidil 2% has also been successfully proven to shorten the period of baldness following chemotherapy.

    Alopecia Areata:

    Alopecia Areata is an autoimmune condition that creates inflammation at the hair follicle which can trigger hair shedding. It generally affects 1 - 2% of the world population and occours in both genders equally, and mostly occours between the ages of 20 - 40. Althought the exact cause is difficult to determine, patients have been found to have an increased amount of hair destroying antibodies. In this condition the immune system attacks the hair follicles.

    In general, sudden hair loss starts with one or more circular patches that can overlap. In General, the cause is not known, but genes appear to play a role, or some kind of enviromental trigger may lead to Alopecia Areata. There is also a chance that the hair will grow back again, however this varies from person to person.

    Lichen Plano Pilaris

    This is a rare inflammatory condition which often affects younger women and usually results in permanent hair loss on the scalp. Redness develops around the hair follicle and they can be easily pulled out. Some patients report having burning, itchiness, and tenderness. Fortunately, this disease is usually slow to progress, and early treatment can help releive symptoms.

    Lichen Plano Pilaris is almost 3 times more likely to affect women, and is mostly seen in Caucasians, in generaly the average age of onset is mid 40s. People suffering from this will have a smooth texture at the areas where hair follicles have been destroyed, and it is usually patchy in appearance.

    DLE Alopecia:

    DLE is also known as discoid lupus erythematosus, which can commonly cause hair loss especially in women. This is an autoimmune disease that leads to scaly patches of skin, scarring, and eventually hair loss. Any change to the scalp can result in permanent scarring, and irreversible alopecia although it does responnd well to corticosteroids.

    Studies have shown that using topical tacrolimus cream can often result in Hair regrowth in some patients.

    In general, you can get a 6 month supply of Minoxidil for around $18 - $20, it may also be worth asking your doctor about Finasteride, even though it is mostly used by men. Some doctors suggest seeing an endocrinologist, since some female hair loss disorders are hormonal in nature.
