Losing around 300 hairs daily is more than normal and may be related to nutritional deficiencies, stress, illness, dandruff, hormonal imbalance, thyroid problems, anaemia, poor sleep, or certain medications. Nutritional deficiencies such as low iron, vitamin D, vitamin B12, zinc, or low protein intake are common causes of excessive hair fall. Instead of starting medicines on your own, it is better to first identify the exact cause through a proper medical evaluation. A dermatologist may advise blood tests to check iron levels, thyroid function, vitamin levels, and overall health before suggesting treatment. In the meantime, focus on improving your diet by eating protein-rich foods such as eggs, milk, curd, pulses, nuts, fish, chicken, soy products, green leafy vegetables, and fresh fruits. Drink enough water and avoid crash dieting or skipping meals. Use a mild shampoo regularly to keep the scalp clean, and if you also have dandruff or itching, a medicated anti-dandruff shampoo containing ketoconazole may help. Avoid frequent hair colouring, straightening, excessive oiling, tight hairstyles, and heat styling, as these can weaken the hair further. Hair supplements containing biotin, iron, zinc, and multivitamins are sometimes prescribed, but they work best when taken under medical guidance and only if a deficiency is present. Stress control, proper sleep, and regular exercise also play an important role in hair recovery. Hair regrowth usually takes a few months, so consistent care and patience are important for visible improvement.
