The loss of hair while combing, washing or sometimes while sleeping, on pillows and bed can be ascertained as a problem of hair fall.
Hair, like human beings, has a life-cycle.
Every hair that grows must fall out one day.
New hair will grow at the same place, after some time.
There is a natural balance between the rate at which hair falls and the rate at which new hair grows.
Any disturbance in this balance can result in an emotionally discomforting condition of either an excess fallout of hair or hairiness all over the body.
Now-a-days, excess loss of hair is very common.
It happens for various reasons such as emotional and physical stress of city life, local scalp infection, adverse drug reaction, hormonal imbalances during teenage and pregnancy, etc.
