Fast hair fall, along with acidity and gas, is often due to stress, poor nutrition, or digestive problems that affect how your body absorbs nutrients. Focus on regular, balanced meals with enough protein, fruits, and vegetables to provide proper nourishment, and avoid long gaps between meals, as this can worsen acidity. Drink enough water, include light daily activity to support digestion, and keep hair care simple without harsh products or excessive styling. Try to maintain good sleep and reduce stress, as these directly affect both digestion and hair health. If hair fall continues to increase or you feel weakness or changes in weight, inform your doctor to rule out nutritional or hormonal causes and guide appropriate care.
