"Coconut Oil And Hair Growth"

So a hair salon in the Philippines told my wife to grow hair on a bald spot use coconut oil. So I was telling my friend about this as he has a nice bald spot that he really don't care that much about. So a few months later I seen my friend and he told me he tried the "Extra Virgin Coconut Oil" and rubbed it on his bald spot and oh wow there was some new hair growing on his bald spot. So coconut oil to a bald spot does grow hair. The only question is how much and how long will it take?.
