Hair loss is a common condition that affects both men and women at different stages of life. While losing a small amount of hair daily is normal, excessive hair loss may indicate an underlying problem. Understanding the causes of hair loss is the first step toward effective treatment and prevention.

What is Normal Hair Loss?

It is normal to lose 50–100 hairs per day as part of the natural hair growth cycle. Hair grows, rests, and sheds in a continuous process. When this cycle is disrupted, noticeable hair loss can occur.

Common Causes of Hair Loss

1. Genetic Hair Loss (Androgenetic Alopecia)

The most common cause of hair loss.

• Affects both men and women
• Known as male or female pattern baldness
• Gradual thinning over time

In men: Receding hairline and bald spots
In women: Diffuse thinning, especially at the crown

2. Hormonal Changes

Hormonal imbalance can significantly affect hair growth.

• Pregnancy and postpartum period
• Menopause
• Thyroid disorders
• Polycystic Ovary Syndrome (PCOS)

3. Nutritional Deficiencies

Lack of essential nutrients can weaken hair.

• Iron deficiency
• Low vitamin D
• Zinc deficiency
• Protein deficiency

4. Stress and Illness (Telogen Effluvium)

Physical or emotional stress can push hair into the shedding phase.

• Severe illness
• Surgery
• Emotional stress
• Rapid weight loss

Hair loss usually occurs 2–3 months after the trigger.

5. Medical Conditions

Certain diseases can cause hair loss:

• Thyroid disorders
• Autoimmune diseases (e.g., alopecia areata)
• Scalp infections

6. Medications

Some medications may lead to hair shedding:

• Chemotherapy drugs
• Blood pressure medications
• Antidepressants
• Hormonal medications

7. Hair Care Practices

Improper hair care can damage hair and scalp:

• Excessive heat styling
• Tight hairstyles (traction alopecia)
• Frequent chemical treatments

8. Environmental Factors

• Pollution
• Sun exposure
• Poor water quality

These factors can weaken hair over time.
