Why does hair loss happen during menopause?

Hair loss is a very common and often distressing symptom experienced during the stages of menopause. Hair thinning or hair loss can occur during perimenopause and throughout the later menopause stages.

As hormone changes during perimenopause occur, many women notice that their hair becomes thinner or that it does not grow as quickly as it once did.

Hormonal shifts during perimenopause and menopause can significantly alter hair growth cycles and scalp health.

Understanding the reasons behind these changes can help you feel more in control and allow you to explore effective ways to manage your hair health.

Why does menopause cause hair loss?

Oestrogen plays a vital role in maintaining the active growth phase of hair follicles. During menopause the levels of oestrogen and progesterone fall which means the effects of androgens (male hormones that are also present in women) can become more noticeable.

These hormonal shifts can cause hair follicles to shrink and spend less time in active growth leading to progressive hair thinning and a slower rate of growth.

Common patterns of hair thinning in menopause

The most frequent pattern of hair loss during this stage is female pattern hair loss (androgenetic alopecia), which typically involves a gradual thinning over the top and crown of the scalp. You may also notice a widening part line or a general reduction in total hair volume rather than complete baldness.

Less commonly, some women experience diffuse hair shedding which is a more rapid loss of hair that can be triggered by sudden hormonal changes or high levels of stress and illness.

Other factors that contribute to hair loss in menopause

While hormones are a primary driver hair changes are often multifactorial and can be influenced by several other health considerations.

Nutritional deficiencies such as low iron or protein intake can significantly impact hair resilience and density.

Furthermore, thyroid function and understanding how high levels of anxiety or stress affect the body can clarify how these factors interfere with the hair growth cycle, often worsening the effects of hormonal decline during the transition towards the menopause milestone.

Managing hair loss during menopause

A comprehensive approach to managing hair loss involves addressing both internal health and external care routines.

Maintaining a balanced diet rich in protein iron zinc and vitamins provides the essential building blocks for resilient hair growth. Using gentle hair care practices and avoiding harsh chemical treatments or high heat styling can also help protect the hair shaft and reduce breakage.

A clinician may discuss evidence-based medical treatment options such as topical minoxidil or appropriate hormone therapy to support the hair follicles.

When to see a doctor

If hair loss is sudden, patchy, or causing distress, it is important to arrange a menopause consultation or see a trichologist. This can provide clarity, help identify the specific drivers of hair changes, and rule out other potential health conditions.

An expert consultation may include checking hormone levels, thyroid function, iron status, and reviewing medications that could contribute to hair loss.

Managing hair concerns during menopause requires a deep understanding of complex growth cycles and underlying medical drivers. Early assessment can help address underlying causes and improve your scalp and hair health.
