My hairs of head are turning white ..plz suggest me what all healthy nutritions i should go for as i already tried medication and didn't work out?

It's you: Some people's hair goes gray early. It's probably genetically programmed; i'm going to assume you do not have any other hair-related problems and are not on a bizarre diet, B12 deficient or hypothyroid. No diet or medication will touch it. You can dye it, or (probably better) you can find a way to laugh. For many, gray hair is a sign of wisdom. Thanks for your courage in writing.

See a doctor: Premature graying can be caused by medical problems like thyroid abnormality. You should see a doctor to have lab work done.
