The nourishment you need for your hair is a simple one. I'm simplistic when it comes to this topic because, just as read articles on tribal Africans and some slaves. They would utilize the grease/oil from whatever animal they were fed or would catch. So I simply applied that to my regimen. Oil and water! When you forget that you have hair but, you remember it needs to be nurtured and you train it to become so. You don't have to worry about much. Simple as that. And most definitely this can apply to everyone it's just a matter of how consistent you choose to be.
