Hair loss affects millions of people worldwide, and understanding its causes is the first step toward effective prevention and treatment. This comprehensive guide explores the various causes of hair loss and provides evidence-based prevention strategies to help you maintain healthy, strong hair.
Understanding Hair Growth Cycle
Before diving into causes, it's important to understand how hair grows:
The Three Phases of Hair Growth
- Anagen Phase: Active growth phase (2-7 years)
- Catagen Phase: Transition phase (2-3 weeks)
- Telogen Phase: Resting phase (3-4 months)
Normally, about 85% of your hair is in the anagen phase, 1% in catagen, and 14% in telogen. Hair loss occurs when this balance is disrupted.
Primary Causes of Hair Loss
1. Genetic Factors (Androgenetic Alopecia)
The most common cause of hair loss in both men and women:
- Male Pattern Baldness: Receding hairline and crown thinning
- Female Pattern Hair Loss: Diffuse thinning across the scalp
- Hereditary Factors: Family history of hair loss
- Hormonal Influence: DHT (dihydrotestosterone) sensitivity
2. Medical Conditions
Various medical conditions can cause hair loss:
- Thyroid Disorders: Hypothyroidism and hyperthyroidism
- Autoimmune Diseases: Alopecia areata, lupus
- Scalp Infections: Ringworm, fungal infections
- Hormonal Imbalances: PCOS, menopause
- Iron Deficiency: Anaemia affecting hair growth
3. Lifestyle and Environmental Factors
- Stress: Physical and emotional stress
- Poor Nutrition: Vitamin and mineral deficiencies
- Hair Care Practices: Harsh treatments and styling
- Environmental Toxins: Pollution and chemical exposure
- Medications: Side effects of certain drugs
