Doctors generally ask several questions related to one’s lifestyle and diet in order to arrive at a diagnosis for hair loss. In some cases, they may perform blood tests, scalp tests and biopsies to ascertain the reason. Depending on the type of hair loss you are suffering from, there are a variety of treatments available. It is essential to correctly diagnose the condition in order to take the preventive steps. Correcting hormonal imbalance, including nutrition rich foods and recognizing and treating underlying infections can prevent further hair loss.
