Introduction
- Hair loss in women is a common condition that can affect the scalp or entire body, resulting from genetic factors, hormonal imbalances, stress, or medical conditions.
- While some hair loss is normal (50–100 strands daily), excessive shedding or thinning warrants investigation.
- Effective management involves identifying the underlying cause, lifestyle adjustments, medical treatments, and supportive care.
