Sudden hair fall started. Industry!

Few months back I have noticed that my hair started falling off from roots. Though I was taking proper diet with all the fats and protein. I consulted a dermatologist in Jaipur and he recommended me to have anrofolM on daily basis after breakfast. Foligain hair lotion daily before sleeping and to wash my hair with keraglo-AD. After doing this for a month I noticed that my hair has stopped falling and it was good and strong. But 2 weeks ago I noticed the same problem of sudden hair fall. Though I was taking all the medications but still the hair fall is happening and earlier when I put my hand in my hair (casually) I noticed nothing but if now I put my hand in my hair I can easily see 4-6 hair in my hand Everytime. And it get worse when I shampoo my hair. I see alot of hair in my hand or on bathroom floor. And my family background is that my father is bald. There is no hair in the centre of his head. The crown part. I'm little worried because I'm a designer working in Bollywood industry
