Hair Loss in Women: What's Really Going On?
Finding more hair in your brush, shower drain, or on your pillow can be incredibly distressing. For many women, hair is closely linked to confidence and identity, so when it starts thinning or shedding, it can feel alarming and overwhelming.
The good news? Hair loss is often a symptom of an underlying imbalance rather than a problem in itself. While it may be tempting to reach for the latest hair supplement or expensive shampoo, true and lasting results come from understanding why the hair loss is occurring in the first place.
Common Causes of Hair Loss in Women
Hair growth is influenced by a complex interplay of hormones, nutrients, stress, genetics, and overall health. When one or more of these factors become disrupted, hair loss can occur.
Iron Deficiency
One of the most common causes of hair loss in women is low iron stores. Iron is essential for delivering oxygen to the hair follicles, and even when iron levels fall within the laboratory "normal" range, they may not be optimal for healthy hair growth.
Women with heavy periods, vegetarian or vegan diets, digestive issues, or a history of pregnancy are particularly at risk.
Thyroid Imbalances
Both an underactive and overactive thyroid can contribute to hair thinning. The thyroid gland plays a key role in regulating metabolism, energy production, and hair growth cycles.
Hair loss is often accompanied by symptoms such as fatigue, weight changes, constipation, anxiety, or temperature sensitivity.
Hormonal Changes
Hormones have a significant impact on hair health throughout a woman's life.
Hair loss may occur during:
Postpartum recovery
Perimenopause and menopause
Polycystic Ovary Syndrome (PCOS)
Following discontinuation of hormonal contraception
Elevated androgens (male hormones), declining oestrogen levels, or hormonal fluctuations can all affect the hair growth cycle and lead to thinning.
Chronic Stress
The body does not differentiate between physical and emotional stress. Work pressures, relationship difficulties, illness, poor sleep, over-exercising, restrictive dieting, and emotional trauma can all trigger a condition known as telogen effluvium.
This occurs when a larger-than-normal percentage of hair follicles enter the resting phase, resulting in increased shedding several months after the stressful event.
Nutrient Deficiencies
Healthy hair requires adequate levels of many nutrients, including:
Iron
Zinc
Protein
Vitamin D
B vitamins
Selenium
Essential fatty acids
Without these building blocks, hair follicles simply cannot function optimally.
Gut Health and Absorption Issues
Even the healthiest diet won't help if nutrients aren't being absorbed effectively.
Conditions such as coeliac disease, SIBO, IBS, inflammatory bowel disease, chronic diarrhoea, or low stomach acid can reduce nutrient absorption and contribute to hair loss over time.
Why Functional Testing Matters
One of the biggest frustrations women face is being told that their blood tests are "normal" despite experiencing significant hair loss.
Standard pathology ranges are designed to identify disease, not necessarily optimal health.
Functional testing allows us to dig deeper and identify potential contributing factors before they become major health issues.
Depending on the individual, testing may include:
Comprehensive blood testing
Iron studies and ferritin
Thyroid function testing
Vitamin D levels
Hormone assessments
Gut health testing
Nutritional status markers
Rather than guessing which supplement may help, testing provides valuable information that allows treatment to be personalised and targeted.
A Holistic Approach to Hair Loss
Hair loss rarely occurs in isolation.
As naturopaths, we look at the entire picture rather than focusing solely on the hair itself.
A holistic treatment plan may include:
Optimising Nutrition
Hair is made primarily from protein, making adequate protein intake essential.
A nutrient-dense diet rich in:
Quality protein
Colourful vegetables
Healthy fats
Seafood
Nuts and seeds
Iron-rich foods
provides the raw materials needed for healthy hair growth.
Supporting Stress and the Nervous System
Many women underestimate the impact chronic stress has on their hair.
Supporting the nervous system through:
Regular movement
Quality sleep
Breathwork
Mindfulness
Time in nature
Appropriate herbal support
can help reduce stress-related hair shedding and improve overall wellbeing.
Addressing Hormonal Imbalances
Where hormonal changes are contributing to hair loss, supporting hormone balance naturally can often improve both hair growth and other symptoms such as fatigue, acne, irregular periods, mood changes, or weight gain.
Improving Gut Health
Addressing digestive dysfunction, improving nutrient absorption, and restoring a healthy gut microbiome can have a profound effect on hair health.
Targeted Supplementation
While supplements can be helpful, they are most effective when tailored to the individual's needs.
The right supplement at the right time can be incredibly valuable. The wrong supplement may simply create expensive urine.
The Takeaway
Hair loss is often your body's way of signalling that something deeper requires attention.
Rather than accepting hair thinning as something you simply have to live with, it's important to investigate the underlying causes and address them appropriately.
By combining functional testing, comprehensive assessment, nutrition, lifestyle support, and targeted supplementation, it is often possible to significantly improve hair health while also enhancing energy, mood, hormones, digestion, and overall wellbeing.
Because when it comes to hair loss, the goal isn't simply to grow more hair—it's to create a healthier body that naturally supports healthy hair growth from the inside out.
