Causes of Hair Loss

There are multiple contributing factors to hair thinning and shedding, ranging from genetics to lifestyle choices. Here’s a breakdown of the most common causes:

1. Genetics

Some individuals have a genetic predisposition to hair loss due to a sensitivity to DHT (dihydrotestosterone). DHT binds to hair follicle receptors, particularly on the scalp, shrinking them over time and leading to gradual hair thinning. This is a primary cause of male and female pattern baldness.

2. Hormonal Imbalances

For women, hormonal fluctuations can play a significant role in hair thinning or excessive shedding. Changes in oestrogen and progesterone levels, particularly during pregnancy, menopause or due to conditions like PCOS, can contribute to female hair loss.

3. Nutritional Deficiencies

A well-balanced diet is essential for hair health and deficiencies in key nutrients can weaken hair follicles. Some essential nutrients include:

 Iron: Low iron levels are one of the most common causes of hair loss globally.

 Zinc: Supports protein synthesis and cellular repair, which are crucial for hair growth.

 Vitamin E: Plays a role in scalp circulation and supports follicle health.

 Amino Acids & Proteins: The building blocks of keratin, which makes up the hair structure.

4. Medical Conditions & Medications

Various medical conditions and medications can contribute to hair loss, including:

 Thyroid disorders

 PCOS (Polycystic Ovary Syndrome)

 Coeliac disease

 Blood thinners, steroids, and antidepressants

5. Stress & Hair Shedding

Chronic stress can lead to Telogen Effluvium, a condition characterised by excessive hair shedding. In a healthy scalp, 85% of the hair is in the growth phase (anagen), while 15% is in the resting phase (telogen). Prolonged stress can push more hairs into the telogen phase, leading to noticeable shedding.
