Introduction
Hair loss is a common concern that affects millions of people worldwide. Whether you notice thinning hair, receding hairlines, or excessive shedding, it can be distressing and impact self confidence. The good news is that understanding the causes and taking preventive steps can help manage hair loss effectively.
What Causes Hair Loss?
Hair loss can happen due to various reasons, including:
1. Genetics (Androgenetic Alopecia)
Also known as male or female pattern baldness, this is the most common cause.
In men, it leads to a receding hairline and bald spots.
In women, it causes overall thinning, especially at the crown.
2. Hormonal Changes
Pregnancy, childbirth, menopause, or thyroid disorders can trigger hair loss.
Conditions like polycystic ovary syndrome (PCOS) may also contribute.
3. Stress and Trauma
Physical or emotional stress (e.g., surgery, illness, or emotional distress) can lead to temporary hair shedding (telogen effluvium).
4. Nutritional Deficiencies
Lack of iron, vitamin D, zinc, or protein weakens hair follicles.
Crash diets or eating disorders can worsen hair health.
5. Medical Conditions & Treatments
Autoimmune diseases like alopecia areata cause patchy hair loss.
Chemotherapy and certain medications may lead to hair thinning.
6. Poor Hair Care Habits
Excessive use of heat styling tools, tight hairstyles (ponytails, braids), and harsh chemical treatments damage hair.
How Does Hair Loss Affect Health?
While hair loss itself isn’t life threatening, it can impact emotional wellbeing. Many people experience:
Lower self esteem and confidence.
Anxiety or depression due to changes in appearance.
Social withdrawal in severe cases.
