Hair fall is a common concern caused by factors such as poor nutrition, stress, hormonal imbalance, pollution, genetics, and unhealthy lifestyle habits. While losing some hair daily is normal, excessive shedding may indicate underlying issues that need attention. Habits like eating junk food, lack of sleep, dehydration, and excessive use of chemical products can worsen hair loss. Prevention focuses on proper nutrition, hydration, scalp care, stress management, and healthy sleep. Biotin can support hair strength and health but is not a miracle cure. Consistent lifestyle improvements remain the most effective way to maintain strong, healthy hair.
