What type of food to eat so that hair grow nicely and what must not eat?

eat coconut oil.. add on your food while cook..

I thought coconut oil good for the hair if you put it on the hair? Will it make hair nicer by eating it also?

coconut oil can use for cook and use for hair also.. but cold pressed oil is more quality..

Cold pressed oil is organic? Do you know how much more expensive than normal oil?

Can share what type of vitamin or supplement can help?
