Why white hair at young age?

For many people, it is from your family. Your genes, you know? If your mum or dad went grey early, you might too. This is the main reason, really. A lot of stress can make it worse, a bit faster. Also, not eating properly is a problem. You might need more vitamins. Like vitamin B12 is an important one. Smoking can also be a cause. Sometimes it is a health thing, like your thyroid. If you are worried, maybe talk to a doctor. They can check for you.
