Introduction & Background

Hair loss, or alopecia, affects millions of people globally and can occur at any age. While losing some hair daily is normal, excessive or sudden hair loss can be distressing and may indicate an underlying health issue. Hair plays a significant role in self-esteem and identity, and understanding the root causes is crucial for effective treatment.

Causes of Hair Loss

Hair loss can result from a wide variety of conditions, including:

1. Genetics (Androgenetic Alopecia): The most common cause, often inherited, leading to male or female pattern baldness.
2. Hormonal Changes: Pregnancy, menopause, thyroid disorders, or hormonal imbalances can trigger hair thinning.
3. Medical Conditions: Autoimmune diseases (e.g., alopecia areata), polycystic ovary syndrome (PCOS), and scalp infections.
4. Medications: Chemotherapy, antidepressants, and drugs for high blood pressure can lead to temporary or permanent hair loss.
5. Nutritional Deficiencies: Lack of iron, protein, zinc, or vitamins like B12 and D can weaken hair follicles.
6. Stress and Trauma: Physical or emotional stress can cause telogen effluvium, a type of temporary hair loss.
7. Hairstyling Practices: Excessive heat, tight hairstyles, or chemical treatments may cause traction alopecia.
8. Aging: Natural aging often leads to slower hair growth and thinning.
9. Radiation or Surgery: Radiation therapy or scalp surgery can damage follicles and result in hair loss.
10. Underlying Chronic Illnesses: Diabetes, lupus, and liver disease can also affect hair health.
