Hair loss or alopecia is defined as someone experiencing unexpected heavy loss of hair. Generally, we shed between 50 to 100 single hairs per day. Hair shedding is part of natural balance where some hair falls out while others grow in. When the balance is interrupted where hair falls out and less hair grows in, hair loss happens.
