Progesterone Hair Loss: Unraveling the Link and Solutions

Progesterone Hair Loss: Unraveling the Link and Solutions

Hair loss can be a distressing experience for anyone, but it’s particularly challenging for women due to societal expectations surrounding hair and beauty. One possible factor contributing to hair loss in women, especially during menopause or hormonal imbalances, is the hormone progesterone. The relationship between progesterone and hair loss is complex, and understanding its role can lead to potential treatments or preventative measures.

Progesterone is a female hormone primarily produced by the ovaries, and it plays a crucial role in regulating the menstrual cycle and maintaining pregnancy. However, its impact on hair growth and hair loss is not as widely understood. Research has shown that progesterone may help decrease the conversion of testosterone into dihydrotestosterone (DHT), a hormone that can cause hair follicles to shrink and ultimately, lead to hair loss. This indirect effect implies the potential benefits of maintaining balanced progesterone levels, especially in the context of hair health.

Moreover, during menopause, a woman’s body undergoes various hormonal changes, with lower levels of progesterone and estrogen being produced. This shift in hormonal balance may contribute to hair thinning and hair loss. Also, micronized progesterone is sometimes recommended to treat signs and symptoms of skin and hair aging in menopausal women, indicating its potential role in managing hair loss. However, further research is required to fully understand the extent of progesterone’s impact on hair and to determine the most effective treatments or interventions for hair loss related to progesterone.

The Role of Progesterone in the Human Body

Progesterone and Hair Growth Cycle

Progesterone is a hormone that plays a crucial role in various processes within the human body. In regard to hair growth, progesterone acts as a natural inhibitor of 5-alpha reductase. This enzyme is found in human scalp hair follicles and is involved in the conversion of testosterone to dihydrotestosterone (DHT). Excess DHT can impact hair follicles, potentially causing hair loss. By blocking 5-alpha-reductase, progesterone helps to reduce the levels of DHT, thus promoting healthy hair growth.

Apart from progesterone, other hormones such as estradiol significantly alter the hair follicle growth and cycle. These hormones act by binding to specific hormone receptors and influencing the activity of enzymes responsible for converting androgen into estrogen (E2).

Hormonal Imbalance in Women

Hormonal imbalances can lead to various symptoms and complications in women, especially during menopause. Progesterone, along with estrogen, plays a critical role in maintaining hormonal balance. Low levels of progesterone can result in an increased production of DHT, which can subsequently cause hair loss. In some cases, micronized progesterone is recommended to help address signs and symptoms of skin and hair aging in menopausal women.

Hormonal fluctuations can also occur during pregnancy, causing changes in hair growth patterns. The increased levels of progesterone during pregnancy help to sustain the hair follicles in the growth phase, leading to thicker hair growth. However, after childbirth, there is a significant drop in hormone levels, which can lead to a period of hair loss known as postpartum hair shedding.

Progesterone plays a vital role in maintaining hair growth and contributes to hormonal balance in women. Imbalances in this hormone can result in hair loss and other symptoms, but appropriate treatment and therapies can help address these concerns.


Understanding Hair Loss

Types of Hair Loss

Hair loss can be classified into several types. Some of the common ones include:

  1. Androgenetic Alopecia: Also known as pattern hair loss, it affects both men and women. In women, this is often referred to as Female Pattern Hair Loss (FPHL).
  2. Alopecia Areata: An autoimmune disorder characterized by hair loss in small, round patches.
  3. Telogen Effluvium: Temporary hair loss caused by an increased number of hair follicles entering the resting phase.
  4. Anagen Effluvium: Hair loss caused by disruptions in the active growth phase of hair, usually due to chemotherapy or radiation treatment.

Causes of Hair Loss

Several factors contribute to hair loss, some of which include:

  • Hormonal Imbalance: Fluctuating hormone levels, especially in women, can lead to hair loss. This can occur during pregnancy, menopause, or due to conditions like Polycystic Ovary Syndrome (PCOS). A well-known example of hormonal hair loss is the role of progesterone. Imbalances in this hormone have been associated with hair thinning and loss.
  • Stress: Both physical and emotional stress can have an impact on hair growth, leading to temporary hair loss.
  • Nutritional Deficiencies: Lack of essential nutrients, such as iron, zinc, and B vitamins, can weaken hair follicles and contribute to hair loss.
  • Medical Conditions: Certain illnesses, such as thyroid disorders and autoimmune diseases, can cause hair loss.
  • Medications: Hair loss can be a side effect of certain medications, including blood thinners, birth control pills, and antidepressants.

Maintaining a well-balanced diet, managing stress, and addressing underlying medical issues can help support healthy hair growth. In cases where hormonal imbalances are contributing to hair loss, consulting with a healthcare provider can help determine the most appropriate treatment options.

Progesterone and Hair Loss

Scientific Studies Relating Progesterone and Hair Loss

Various scientific studies have examined the relationship between progesterone and hair loss. For instance, one study found that progesterone reduces the conversion of testosterone to dihydrotestosterone (DHT), which is known to cause hair follicle shrinkage and contribute to hair loss. However, it is essential to note that the direct link between progesterone levels and hair loss has not been firmly established.

Another study focused on the impact of progesterone on skin and hair in menopause. The researchers concluded that micronized progesterone might help treat the signs and symptoms of skin and hair aging in menopausal women. It is important to understand that this review primarily focused on the effects of progesterone therapy on aging skin and hair, rather than specifically addressing hair loss.

Effects of Low Progesterone on Hair Loss

Low progesterone levels may indirectly contribute to hair loss in several ways. As we know, progesterone can decrease the conversion of testosterone to DHT. Thus, a decrease in progesterone levels may potentially lead to increased DHT levels, consequently causing hair loss. Additionally, low progesterone levels can result in hormonal imbalances, which can cause various health issues, possibly including hair loss.

To manage hair loss associated with hormonal imbalances, doctors may recommend different treatments. For example, FDA-approved topical minoxidil 5% foam is a common medication prescribed to treat female pattern hair loss.

While progesterone has some connection to hair loss, it’s crucial to consult with a healthcare professional for accurate diagnosis and proper treatment options regarding hormonal imbalances and hair loss.

Using Progesterone for Hair Regrowth

Progesterone Cream for Hair Loss

Progesterone is a natural hormone that plays a vital role in the hair growth process. It works as an inhibitor of 5-alpha reductase, an enzyme found in the human scalp hair follicles. Progesterone cream can be applied topically to the scalp to help promote hair growth by reducing dihydrotestosterone (DHT) levels, a hormone that contributes to hair loss.

When using progesterone cream for hair loss, it is crucial to follow the product’s instructions and consult with a healthcare professional for proper guidance. It’s important to consistently apply the cream as recommended to ensure optimal results.

Oral Progesterone for Hair Regrowth

Oral progesterone, usually in the form of hormone replacement therapy, is another option for treating hair loss in women. However, the effectiveness of oral progesterone for hair regrowth varies among individuals, and it is essential to discuss this treatment option with a healthcare professional.

Please note that while oral progesterone may help with hair regrowth, it may also come with potential side effects. Women considering this treatment option should be aware of these risks and weigh the pros and cons with their healthcare provider.

Possible Side Effects and Risks

Progesterone, a hormone commonly found in birth control medications and hormone replacement therapy, has been linked to hair loss in some cases. It is important to be aware of possible side effects and risks associated with progesterone use.

One of the most common side effects of progesterone use is chest pain, which may be accompanied by chills, cold or flu-like symptoms, cough, hoarseness, fever, and problems with urination. Less common side effects include clear or bloody discharge from the nipple, dimpling of the breast skin, inverted nipple, and lump in the breast or under the arm.

In addition to these side effects, any hormonal form of birth control, including oral pills, skin patches, hormone injections, and implants, can cause hair loss. The ingredient in these products that may contribute to hair loss is progesterone.

Some reported hair loss cases are related to the specific type of progesterone used in the medication. Micronized progesterone (MP) has been recommended to treat signs and symptoms of skin and hair aging in menopausal women. It is important to discuss with your healthcare provider about the type of progesterone you are taking if you are experiencing hair loss.

It is essential to be aware of the possible side effects and risks associated with progesterone use, including hair loss. Consult your healthcare professional before using any hormonal medication and to discuss alternative options if you experience hair loss.


Progesterone is a steroid hormone that plays a significant role in female reproduction and has an impact on various body tissues, including the skin and hair. In the context of hair loss, the relationship between progesterone and hair growth is complex but noteworthy.

Research suggests that progesterone, at the level of the hair follicle, may help decrease the conversion of testosterone into dihydrotestosterone (DHT). DHT is known to be a primary factor in the development of androgenetic alopecia, or pattern hair loss.

Moreover, studies have explored the effects of hormonal therapy in female pattern hair loss. While it has been observed that micronized progesterone (MP) is recommended to treat skin and hair aging symptoms in menopausal women1, the evidence is limited, and further research is needed to validate the effectiveness of progesterone therapy in hair loss treatment.

In conclusion, understanding the role of progesterone in hair loss is crucial for both patients and healthcare professionals. It is essential to provide evidence-based treatment options and ensure relevant lifestyle adjustments and proper hair care to promote healthy hair growth.

Frequently Asked Questions

Progesterone supplements may help with hair loss in some cases, as progesterone is known to play a role in the hair growth cycle. For instance, during menopause, when progesterone levels decrease, hair loss may occur. A study on the impact of progesterone on skin and hair in menopause suggested that micronized progesterone (MP) might be effective in preventing or slowing down signs of hair aging.

Hormonal imbalance can be a significant factor in hair loss, especially in women experiencing menopause. The primary hormones associated with hair growth are estrogen and progesterone. An imbalance, such as a drop in estrogen and progesterone levels, can cause hair follicles to shrink, leading to thinner hair strands and overall hair thinning.
