I am 20 year old boy.  lots of my hairs are falling  from last one month. I almost lose 50 hairs a day. I am totally worried. Whenever i rub my hand over the head, i find atleast 2 to 3 hairs. Before  it was  not falling  like this. When i observe the fallen hair, i can see a very small white head at the end. It is falling from roots. No one is bald in the family of father as well as mother. My hair has become thinner. I am totally tensed. Is it normal? Please help me

Do i get those hairs back?
