Is Your Hair falling out too much? Everyday Shedding vs. True Hair Loss

19 Sep 2025

It’s normal to lose some hair every day, on average, between 50 and 100 strands. This is part of the natural growth cycle. However, if you’re noticing clumps of hair falling out, thinning patches, or an overall reduction in volume, that may point to something more than everyday shedding.

Medical Causes of Hair Loss

1. Iron Deficiency

Low iron levels are one of the most common non-genetic causes of hair loss. Iron is essential for healthy hair growth, and deficiency can lead to shedding and weaker strands.
A quick Iron Profile Test can confirm whether low iron is contributing to your symptoms.

2. Thyroid Disorders

Both overactive (hyperthyroidism) and underactive (hypothyroidism) thyroid conditions can disrupt the hair growth cycle, causing hair to thin or fall out.
A Thyroid Function Test helps check whether your thyroid is affecting your hair.

3. Hormonal Changes

For women, hormonal fluctuations due to pregnancy, menopause, or conditions like PCOS can trigger hair thinning. For men, low testosterone or other hormonal imbalances may play a role.
Our Women’s Health Services and Men’s Health Services include hormone checks tailored to these concerns.

4. Vitamin Deficiencies

Low levels of vitamin D, B12, and zinc are linked with poor hair health. These deficiencies can cause hair to become brittle and more likely to shed.

5. Stress and Illness

Significant stress or illnesses, including infections, can cause a temporary type of hair loss called telogen effluvium, where more hairs than usual enter the shedding phase.

When to See a Doctor

While mild hair shedding may not need medical attention, you should consider booking a consultation if:

• Hair loss is sudden or severe
• You notice bald patches or overall thinning
• Hair loss is accompanied by fatigue, weight changes, or irregular periods
• You’re unsure whether the cause is genetic or medical

You can arrange a Private GP Appointment to discuss your symptoms and explore possible tests.

The Role of Testing

Because hair loss can have many causes, testing can save time and provide clarity. Depending on your situation, your doctor may suggest:

• Iron and ferritin levels
• Thyroid hormone tests
• Hormone profiles (male or female)
• Vitamin checks

At South Kensington Medical & Dental, we offer same-day Blood Tests with results reviewed by experienced doctors.

Can Lifestyle Make a Difference?

While medical issues should be ruled out, some everyday habits can also influence hair health. Helpful steps include:

• Eating a balanced diet with protein, iron, and vitamins
• Reducing stress with relaxation techniques or exercise
• Avoiding excessive heat styling or harsh chemical treatments
• Keeping hydrated

These changes may not stop genetic hair loss, but they can improve overall hair strength and support healthy growth.

Final Thoughts

Hair loss can feel worrying, but it’s not always down to genetics. Deficiencies, thyroid issues, hormones, and stress can all play a part — and the good news is that many of these causes are treatable once identified.

If you’ve noticed more hair shedding than usual, it’s worth getting checked. A simple conversation with a doctor and a few targeted tests can provide answers and help you regain confidence in your health.
