Coconut milk for hair

Yushin is turning 3 this coming June but we are getting worried about her hair. It is not really a big deal but if you can see her hair, it is not fit for her age. Usually kids in the age of 3 should have at least shoulder length hair but some say it will still be depending on the hair growth hormone of a person. We already consulted a doctor regarding this and we were advised not to be worried much since her hair growth is normal. Look at her and her hair: 

My pals informed me about the coconut milk that is known for helping hair grow faster. So that Yushin will have the best hair, I am planning to try it for her hair. And I am hoping for best result soon.
