Hello, Treatment for hair fall depends upon the cause of the condition and also your gender. Many hair fall problems can arise due to underlying hormonal imbalance, thyroid disorders , nutritional deficiencies, any underlying illness, stress just to name few. Proper treatment will need a detailed history with proper hair analysis and if need be some blood tests also. Just taking biotin supplements wont be of much help. Timely treatment is necessary. if you delay the treatment , then it may be difficult to regain all the hair you have lost despite the best treatment you may take at that time. I would suggest you to consult a good dermatologist in your area and follow up at regular intervals.
