Quick facts about Hair loss
- A little over 10% of women under 50 experience noticeable hair loss at some point of their lives - not counting pregnancy or postpartum.
- Up to 75% of women will experience hair loss or hair thinning after the age of 65.
- Among elderly women, hair thinning is as prevalent as among elderly men.
It is well known that men commonly suffer from “male pattern baldness” or a progressively receding hairline with a bald spot on the top, which worsens as they age. However, female hair loss -medically termed female alopecia - doesn't usually get as much attention even if it's surprisingly common. Most of the time alopecia acts as a symptom of an underlying imbalance or hidden condition rather than as a disease by itself.
The significant hormonal changes that take place during a woman's reproductive life (from puberty to menopause, including pregnancy and the post-partum period), especially the balance between testosterone and estrogen, are one of the most common hidden imbalances behind female hair loss. It is important then to see hair health as a mirror of the body's overall health, since many types of hormonal imbalance behind alopecia can eventually cause deeper health issues.
Understanding the Hair Growth Cycle
In order to understand the different types of hair loss that can present themselves in women, it is necessary to know first how the hair growth cycle works and how it changes from growing to resting or shedding. The hair growth cycle consists of three phases:
- Anagen phase is the growing stage, and it lasts from 2 to 8 years
- Catagen phase is a transitional stage, that sees the hair follicle shrink and lasts 2 weeks to a month
- Telogen phase is a resting period, where the hair stops growing completely. Normally, it lasts around 3 months. Once telogen phase is over, the old strand of hair will be pushed from the follicle by a new one.
Under normal circumstances no more than 15% of the total scalp hair is undergoing telogen phase at any given time. This is why everybody loses approximately 150 hairs every day, and this should not be a cause of concern.
Identifying Hair Loss
There are several ways and patterns for female alopecia to present itself, and each one of them may have different causes or possible treatments.
In order to understand the processes behind hair loss, continue on to the next section to read more about their hormonal and non-hormonal causes.
Learning about the causes of hair loss provides the key to understanding how to prevent and treat this troublesome symptom. While the exact causes of hair loss are complex, most doctors and researchers point out that most of the time hormonal changes are the primary cause of hair loss. In addition to these completely normal hormonal causes, other factors and medical conditions may also cause hair loss.
Continue reading to learn more about both the hormonal and other causes of hair loss.
Hormonal Causes of Hair Loss
Hormones are chemical messengers that control every organ in the body, so when changes in these hormone levels occur, certain health disorders can arise. Medical researchers have found that fluctuating levels of hormones, especially estrogen and testosterone, make women more susceptible to experiencing hair loss at certain points of their reproductive life.
While androgenic alopecia is directly linked to an excessive amount of testosterone in a woman's body, the hormonal causes of telogen effluvium are linked mostly to estrogen and progesterone levels. Low levels of estrogen or sharp fluctuations between estrogen and progesterone can push hair follicles into telogen phase (or resting phase) prematurely, and to start falling one or two months later. Hence the reason why more women experience hair loss during times of significant hormonal imbalance - puberty, PMS, menstruation, pregnancy, postpartum, and menopause.
Furthermore, there are also specific hormonal causes and typical environmental factors which can explain the occurrence of hair loss according to the stage of a women's reproductive life in which this disorder appears, such as around PMS and during puberty, pregnancy, post-partum, and menopause.
Other Less Common Causes of Hair Loss
While hormonal imbalance is the major underlying cause of female alopecia during a woman's life, experts also point out that hair loss may be caused by other, less common, underlying conditions, including thyroid disorders, metabolic syndrome, or certain skin conditions.
Keep reading to learn more about the risk factors for chronic, recurring hair loss, and the triggers for episodes of abrupt hair loss - especially telogen effluvium.
Risk Factors and Triggers
Risk factors for Hair Loss
Some women are more likely than others to suffer from hair loss because of inherent psychological, behavioral, and health reasons - such as obesity, stress, or past emotional trauma. These predisposing factors can affect a woman's hormone levels and increase the chances of developing hair loss during her reproductive life.
Triggers of Hair Loss
In addition to long term risk factors, hair loss - especially telogen effluvium - can be abruptly triggered by certain environmental factors or stressful events. However, because hair usually remains in telogen phase for one to three months before being “expelled “ from the scalp by a new anagen hair, in order to identify these triggers many women need to draft their history up to three months back in order to identify what caused a massive amount of hair to enter telogen phase.

Signs and Symptoms
While it is normal to lose up to 100 hairs per day, when excessive hair loss occurs many women are able to notice it themselves, either by finding more hairs after washing it or combing it, or by noticing there is an unusual amount of hair left on their pillows. On the other hand, other women may be confused because they don't know if the amount of hair they are shedding is normal, precipitating anxiety.
Common Symptoms of Hair Loss
- Hair thinning on top of the head.
- Scalp becomes more visible in certain areas, particularly the parting line.
- If the hair is long enough to be tied on a ponytail, it will become smaller or require a smaller elastic band.
What other symptoms might occur with hair loss?
In addition to these general indicators of hair loss, there are some symptoms that are specific to one type of hair loss and that can be used to identify it.
Diagnosis of Hair Loss
To diagnose and identify these symptoms, the doctor usually must perform three procedures: a review of the patient's medical history, a physical exam, and a pull test. In some cases, if necessary, the doctor also may order some tests.
Women who experience hair loss may wish to treat it or learn how to prevent it. Keep reading below to learn useful techniques and habits that will prevent hair loss or make it more manageable.
Prevention and Management
Preventing Hair Loss
While there is no single way to completely prevent hair loss, just as there is no way to stave off natural hormonal processes, there are a few steps that a woman can take to lessen her chances of developing severe hair loss, or to minimize the frequency or intensity of her shedding.
Lifestyle changes for prevention are extremely important, especially with regard to diet, exercise, and healthy habits. Moreover, women may seek ways to complement these lifestyle approaches with the use of supplements that help enhance the endocrine system and, therefore, help prevent or ease symptoms of hormonal imbalance such as hair loss.
For women who have already suffer from hair loss, prevention may no longer be possible, but there are many ways to help manage the symptoms. Keep reading to learn about the different ways to manage hair loss.
Managing Hair Loss
With practice and self control, some women can make any hair loss they are already experiencing be as unnoticeable and comfortable as possible. Making minor daily changes ad avoiding triggers can make a huge difference for women trying to manage or hide their hair loss.
While these measures often help to reduce the intensity of hair loss or slow it down, they are unable to treat the root of the problem, which in most cases is hormonal imbalance. However, there are several natural treatments that can fix the hormonal causes of hair loss. Please continue to the next section to learn more about treating hair loss.
For some women, there may be a point in their lives when experiencing some hair loss will be inevitable. Fortunately, because hair loss is usually a consequence of fluctuations in hormones such as estrogen, testosterone and progesterone, it is possible to treat this imbalance.
Three Approaches to Treat Hair Loss
Three levels of approaches can be considered for treating hair loss. These are categorized as: (1) Lifestyle Changes, (2) Alternative Medicine and (3) Pharmaceutical and Surgical Options.
Women are encouraged to begin with the least risky approach to hair loss treatment, lifestyle adjustments, and then proceed to the next level of care. While medical intervention is not usually necessary to treat hair loss, some women who are unable to find relief from lifestyle changes and alternative medicine may wish to consider pharmaceutical or surgical options, after properly assessing the risks associated with such a treatment.
Lifestyle Changes for Hair Loss
This primary level of treatment for hair loss involves the least amount of risk, though conversely it requires the highest amount of self discipline. Often simple changes in lifestyle can reap huge benefits in fighting hair loss and achieving a higher overall level of health. Fundamentally, an improved diet, regular exercise, and healthy habits can do a woman a great service.
While these changes will help alleviate hair loss, they do not directly address hormonal imbalance - the most common cause of hair loss in women - so further treatment may be necessary. Alternative medicine has proven to be an excellent way of treating hair loss when related to hormonal imbalance in a safe and natural way.
Alternative Medicine for Hair Loss
Alternative medicines and supplements involve little to no risk and can be an extremely effective way to treat hair loss. In the case of herbal supplements, there are two main types that can be used: phytoestrogenic and hormone-regulating herbal supplements
Phytoestrogenic herbal supplements
These supplements, such as dong quai, contain estrogenic components produced by plants that complement the low estrogen hormones in a woman's body, helping diminish and treat hair loss. By introducing plant-based estrogens into the body, these herbs treat the underlying estrogen deficiency behind hair loss.
They are mainly effective for menopausal women who are more likely to have low estrogen levels and experience androgenic alopecia but are not necessarily effective for women in other stages of life such as puberty, or for cases of telogen effluvium.
Hormone-regulating herbal supplements
These supplements, including Macafem stimulate the body's natural hormone production by nourishing the pituitary and endocrine glands, helping the whole hormonal system produce hormones more efficiently. This ultimately results in balancing not only estrogen but other important hormones such as progesterone.
These supplements can be considered the safest and most natural way to treat the underlying hormonal imbalance behind hair loss, and can be taken throughout a woman's life, as they support the body's natural hormone production.
Additionally, there are some other types of supplements that can also alleviate hair loss, or at least make it more manageable, including vitamin and other herbal supplements.
A combination of approaches is usually the most effective route to take. Lifestyle changes combined with alternative medicine will most likely be the best way to stop and reverse hair loss. However, for some women the symptoms will be so severe that a more drastic treatment is necessary.
Pharmaceutical and Surgical Options for Hair Loss
Interventions at the third level involve the highest risk and often the highest costs. Not all treatments are suitable for women at every life stage, so it is strongly recommended to speak to a licensed healthcare practitioner before starting any pharmaceutical treatments for hair loss.
There are two main types of medical options that can be prescribed to treat hair loss: hormone-regulating medication and follicular unit transplants.
These three levels of approaches are not mutually exclusive. A woman may use different approaches at different times or any combination of them to treat hair loss, depending on the duration and severity of symptoms. Today more and more women find that dealing with hair loss is best accomplished via a combination of healthy lifestyle and alternative treatments.
