Around One in Two Postmenopausal Women Experience Hair Loss, Study Finds

Menopause Research: Female hair loss affects more than half of postmenopausal women

Changes in hair density is a concern many women share during the menopause transition. It often begins in perimenopause and continues after menopause, although it is much more noticeable in some women than others.

For many women, noticing more hair in the brush, a widening parting, thinning around the crown, or even a receding hairline can be worrying, particularly when they are unsure whether these changes are a normal part of the menopause transition or something that should be investigated.

What the Researchers Examined

Although this condition is widely recognized by healthcare professionals, surprisingly little research has measured its prevalence after menopause.

This cross-sectional observational study was conducted to determine the prevalence and severity in postmenopausal women, providing a clearer picture of how many women are affected and how severe these changes typically are.

The researchers recruited 200 healthy postmenopausal women between the ages of 50 and 65 years. After exclusions, 178 women were included in the final analysis. Women who had recently undergone treatment for this condition were excluded.

The researchers first gathered detailed baseline data, including age, time since menopause, BMI, family history of hair loss, scalp oil production, testosterone and estradiol levels, thyroid-stimulating hormone, haemoglobin, and self-esteem.

Each woman then underwent a thorough dermatological examination, including standardized scalp photographs taken from six different views. The researchers also used trichoscopy, a magnified examination of the scalp and hair, to assess hair density and hair-shaft diameter.

Three dermatologists then independently reviewed the photographs to confirm the diagnosis. Severity was graded using the Ludwig classification system, which classifies this condition as mild, moderate, or advanced.

By combining these clinical examinations with the participants’ health profiles, the researchers were able to determine how common and severe the condition was and investigate whether factors such as age, time since menopause, BMI, hormone levels, and family history were associated with it.

What They Discovered

The researchers found that 93 of the 178 women (52.2%) had female pattern hair loss, meaning that around one in every two postmenopausal women in the study was affected.

Most women with hair loss had mild thinning. Of the 93 women diagnosed, 73.2% were classified as having mild loss (Ludwig Grade I). 22.6% were classified as having moderate loss (Grade II), while only 4.3% were diagnosed with advanced hair loss (Grade III).

The findings also highlighted the emotional impact. Low self-esteem was reported by 60% of the women and became more common as the severity increased.

In addition to measuring prevalence, the researchers examined whether certain characteristics were also associated. Their initial analysis suggested that increasing age, a longer time since menopause, and a higher body mass index (BMI) were all linked to the condition.

However, after adjusting for age and family history, only a BMI of 25 kg/m² or higher remained independently associated with this condition. Women in this group had approximately 2.65 times the odds compared with women whose BMI was below 25 kg/m².

Overall, the findings showed this condition was very common; most women experienced only mild thinning rather than moderate or advanced symptoms. This suggests that while hair thinning affects many women after menopause, it often develops gradually rather than appearing suddenly or becoming severe.

Why It Matters

These changes in hair density are often dismissed as an unavoidable part of getting older, yet this study shows that it is very common after menopause, affecting around one in two women during postmenopause. This helps to normalize an experience that many women find distressing or isolating.

Although this study did not investigate the causes of hair loss, decades of research suggest that hormonal changes during the menopause transition play an important role. As estrogen levels decline, the hormonal environment surrounding the hair follicles changes.

At the same time, the balance between estrogen and androgens also shifts. While scalp hair may gradually become thinner, some women also notice unwanted facial hair after menopause because facial hair follicles can respond differently to these hormonal changes.

In women who are genetically predisposed to hair loss, these hormonal changes are thought to contribute to the gradual shrinking of the hair follicles, resulting in thinner, finer hair and reduced hair density over time.

The researchers also examined several factors that might be associated with this condition. After taking age and family history into account, they found that a body mass index (BMI) of 25 kg/m² or higher remained independently associated with the condition.

It is important to note that this does not mean a higher BMI causes hair loss. Rather, it suggests that body weight may be one of several factors associated along with hormonal changes, genetics, and aging.

Study Limitations

Like all research, this study has some limitations. Because it was a cross-sectional observational study, it provides a snapshot of female hair loss in postmenopausal women at a single point in time. This means it can identify associations between hair loss and factors such as BMI, but it cannot determine whether those factors caused the hair loss.

The study also included a relatively small group of 178 healthy postmenopausal women from a single medical centre. Women who had recently undergone treatment for hair loss were excluded, allowing the researchers to focus on otherwise healthy postmenopausal women. However, this also means the findings may not apply to all women after menopause.

In addition, the study was limited to women aged 50 to 65, so the results may not reflect the prevalence or severity of female hair loss in older postmenopausal women.

Finally, because the study only included postmenopausal women, it cannot tell us when this change first began. Many women notice changes during perimenopause, but this study was designed to measure how common this condition is after menopause rather than track its development over time.

Lillepin Takeaway

This study suggests that female pattern hair loss is very common after menopause, affecting around one in every two postmenopausal women. While this can be upsetting, the findings are also reassuring: most women had only mild hair thinning rather than moderate or advanced hair loss.

The study cannot explain why some women develop this condition while others do not. However, it adds to growing evidence that it is a common part of the menopause transition and deserves greater recognition and earlier discussion between women and their healthcare professionals.

Recognizing the early signs may encourage women to seek advice sooner. Although hair loss cannot always be prevented, early assessment can help identify contributing factors and discuss appropriate treatment options where needed.

Perhaps most importantly, this research reminds us that this condition during and after menopause is both common and real. Many women experience it, yet it often receives far less attention than other menopause symptoms. Understanding that these changes are shared by many women can help reduce unnecessary worry and encourage earlier conversations with healthcare professionals.
