Iron & Ferritin Levels and Hair Loss in Women

Part 1 of Our Hair Nutrition & Scalp Health Series

If you’ve noticed increased hair shedding, widening through your parting, or your hair feeling thinner than usual, it can feel worrying and confusing.

At Hove Hair Clinic, low iron and ferritin levels are one of the most common underlying causes of hair thinning and diffuse hair loss we see in women.

Hair health is closely connected to overall wellbeing, nutrition and scalp health. When iron stores become depleted, the hair growth cycle can be disrupted - often leading to excessive shedding, slower regrowth and reduced hair density.

In this first article of our Hair Nutrition & Vitamin Series, we explore how iron and ferritin levels can affect healthy hair growth, what symptoms to look out for, and when professional hair loss treatment advice may help.

Key Takeaways

• Low ferritin levels are one of the most common causes of hair thinning and excessive shedding in women
• Hair follicles require iron and oxygen to support healthy growth
• Hair changes can occur even before anaemia develops
• Blood testing is important before taking iron supplements
• Supporting scalp health and overall nutrition may improve hair quality and regrowth
• Ongoing hair thinning should always be properly investigated

What Is Ferritin and Why Does It Matter for Hair Growth?

Ferritin is the stored form of iron in your body. It acts as your reserve supply, helping ensure your body has enough iron available when it needs it most.

Iron plays an important role in:

• Carrying oxygen around the body
• Supporting healthy cell function
• Nourishing the hair follicle
• Maintaining healthy scalp health and circulation

Hair follicles are highly active structures that require a consistent supply of oxygen and nutrients to function properly.

When ferritin levels are low, the body prioritises vital organs over non-essential functions like hair growth. This can disrupt the hair growth cycle and contribute to hair thinning and excessive shedding.

How Low Ferritin Levels Can Cause Hair Loss and Hair Thinning

Low ferritin levels do not always cause obvious symptoms immediately. For many women, the first noticeable sign may actually be changes in their hair.

You may notice:

• Increased hair shedding during washing or brushing
• Hair feeling finer or less dense
• Thinning through the top, crown or sides
• Reduced ponytail thickness
• Slower hair regrowth
• More visible scalp in certain areas

This type of hair loss is often described as diffuse thinning, meaning it occurs gradually across the scalp rather than in isolated patches.

At Hove Hair Clinic, we frequently see low ferritin levels contributing to female hair thinning and ongoing shedding concerns.

How Common Is Iron Deficiency in Women?

Iron deficiency is extremely common, particularly in women. You may be surprised to know:

• Around 1 in 4 women of reproductive age worldwide are affected by iron deficiency
• In the UK, iron deficiency anaemia affects approximately 8% of women
• Many more individuals experience low ferritin levels without being classed as anaemic

Because hair follicles are sensitive to nutritional depletion, hair changes can sometimes occur before more serious symptoms develop.

Common Causes of Low Iron and Ferritin Levels

There are many reasons ferritin levels may become depleted over time. Common causes include:

• Heavy menstrual cycles
• Pregnancy and postpartum recovery
• Low dietary iron intake
• Vegetarian or vegan diets without adequate iron sources
• Digestive or absorption issues
• Chronic stress and long-term depletion
• Certain medications or health conditions

Understanding the underlying cause is important when addressing both hair loss and scalp health concerns.

Signs Your Iron Levels May Be Affecting Your Hair

Hair thinning is often only one part of the picture. You may also notice:

• Fatigue or low energy
• Dizziness or headaches
• Shortness of breath
• Pale skin
• Brittle nails
• Difficulty concentrating

If these symptoms appear alongside increased shedding or reduced hair density, it may be worth investigating your iron and ferritin levels further.

Why Blood Testing Matters Before Taking Supplements

Iron deficiency should never be self-diagnosed. It is important to have proper blood testing before taking iron supplements or making significant dietary changes. Too much iron can also create health problems, so professional guidance is always recommended.

At Hove Hair Clinic, we often encourage clients experiencing ongoing hair thinning or excessive shedding to speak with their GP or healthcare provider about appropriate blood testing as part of a broader hair loss treatment approach.

What Is the Ideal Ferritin Level for Healthy Hair Growth?

For general health, ferritin levels may sometimes be considered “normal” at relatively low ranges. However, for healthy hair growth, optimal levels are often higher.

For many individuals experiencing hair thinning, we typically want to see Ferritin levels around 70 or above. Anything significantly lower may begin to impact the hair growth cycle and contribute to ongoing shedding or slower regrowth.

How to Support Healthy Iron Levels Naturally

If testing confirms low ferritin levels, there are several ways to support your body and overall scalp health. These may include:

• Eating iron-rich foods such as red meat, leafy greens, lentils and fortified cereals
• Pairing iron-rich foods with vitamin C to improve absorption
• Avoiding tea and coffee close to meals
• Taking supplements if professionally advised
• Supporting long-term nutritional consistency
• Managing stress and supporting overall wellbeing

Healthy hair growth often depends on a combination of internal nutrition and external scalp health support. Read our Nourish to Flourish blog post for more!

What Happens to Hair Growth When Ferritin Levels Improve?

As iron stores improve, many people notice gradual changes in both their hair and overall wellbeing. Potential improvements may include:

• Reduced shedding
• Stronger, thicker-feeling hair
• Improved regrowth
• Better scalp condition
• Increased energy levels

Because hair grows in cycles, improvement is usually gradual and requires patience and consistency over time.

When to Seek Professional Advice for Hair Loss

Hair loss and hair thinning can have multiple underlying causes, including nutritional deficiencies, hormonal changes, stress, inflammation and scalp conditions.

If shedding continues for several months, or you are noticing visible thinning or reduced density, it is important to seek professional advice rather than relying on guesswork.

At Hove Hair Clinic, we take a holistic approach to hair loss treatment and scalp health, helping identify possible contributing factors that may be affecting healthy hair growth.

Professional hair and scalp treatments, combined with appropriate nutritional support, can often play an important role in improving scalp condition and supporting healthier hair over time.

FAQs About Iron Levels and Hair Loss

A few questions we often hear about Iron levels and hair loss. If your question is not here, please give us a call on 01273 711140 or book an appointment and come and see us!

Can low ferritin cause hair loss even if iron levels appear normal?

Yes. Ferritin measures stored iron, and it is possible to experience hair shedding and hair thinning even when standard iron levels fall within normal ranges.

How long does it take for hair to recover after improving ferritin levels?

Hair recovery is gradual. Many people notice reduced shedding within a few months, while visible improvements in thickness and regrowth may take longer depending on the severity and duration of deficiency.

Can stress contribute to low ferritin and hair shedding?

Chronic stress may contribute indirectly through nutritional depletion, inflammation and disruption to the hair growth cycle.

Should I take iron supplements for hair loss?

It is important to have blood tests first. Taking iron unnecessarily may cause side effects and may not address the true underlying cause of hair thinning.

Can scalp health affect hair growth alongside iron levels?

Yes. Healthy scalp condition, circulation and reduced inflammation all help create a better environment for healthy hair growth.
