hi meri beti 3years10 months ki hai usko hair fall ho raha hai or gray hair bhi or ek white hair dekha aisa kyu ho raha hai?

A. It Can we due to some deficiency of calcium in the body but grey hair is becoming a part of a child thing now so don’t worry about it it’s very common because of the kind of food we are eating at all adulterated so that is why it may be happening in hair fall could be due to some infection in the scalp please can you check
