Hi, There are a number of reasons for hair fall ranging from nutritional deficiencies, hormonal imbalances like PCOD, thyroid disorder, any high fever in the last 6 months, use of a lot of harsh chemicals or chemical salon treatments, female pattern hair loss so on and so forth. You need to visit a dermatologist, get a detailed examination done to find out the reason and get treated accordingly. Dr Rashmi Soni Lohiya (MD, DNB, DDV )
