Hair Loss: Everything You Need to Know About Hair Loss?
Hair loss is a common concern affecting millions of men and women worldwide. While losing a few strands daily is normal, excessive or sudden hair fall can be distressing and may signal an underlying issue. Understanding the causes, types, and treatment options for hair loss can help you take timely and effective action.
What Is Hair Loss?
Hair loss, medically known as alopecia, occurs when hair falls out faster than it grows back. It can affect the scalp or the entire body and may be temporary or permanent. Hair loss can develop gradually over time or appear suddenly, depending on the cause.
Common Causes Hair Loss
Several factors can contribute to hair loss, including:
1. Genetics
Hereditary hair loss, also called androgenetic alopecia, is the most common cause. It usually appears as a receding hairline or thinning crown in men and overall thinning in women.
2. Hormonal Changes
Pregnancy, childbirth, menopause, thyroid disorders, and conditions like PCOS can disrupt hormone levels and trigger hair fall.
3. Nutritional Deficiencies
Lack of essential nutrients such as iron, protein, zinc, biotin, and vitamin D can weaken hair follicles and slow hair growth.
4. Stress and Lifestyle Factors
Physical or emotional stress, poor sleep, smoking, crash dieting, and excessive styling or heat treatments can all lead to increased hair fall.
5. Medical Conditions and Medications
Autoimmune diseases, scalp infections, chemotherapy, antidepressants, and blood pressure medications may cause temporary or permanent hair loss.

- Androgenetic Alopecia: Genetic pattern hair loss
