This is a question on a lot of people's minds. These days the products and myths that claim to do just that are quite incredible.But the bottom line is this:If your natural hair does not seem to grow, then something is NOT right somewhere.Your hair should (naturally) grow up to or more than 6 inches in ONE year. That's more than half an inch a month! That may not seem like a lot to most people, but just get a ruler and check how long six inches is.Hair Growth - The BasicsIn order to know how to grow long black hair, you need to first understand how it behaves and what makes it flourish.Black hair as with any other hair needs plenty of nutrients pumped at the base of the hair follicle in order to grow. The more nutrients you give the hair follicle the longer your hair will grow. For years, people have done all kinds of things in order to stimulate hair growth - remember the hair pulling or brushing to get more blood flow to the base etc.The idea behind hair growth is to stimulate the scalp enough to encourage the blood vessels at the bottom of the hair follicle to deliver more blood than usual to the follicle so that the follicle can get the nutrients from the blood that it needs to make your hair grow. That's the simple explanation and it works most of the time.The only time this will not work is if the follicle has died and can no longer produce any hair, no matter what you do. If it is still active but had been a little bit slow because of diseased etc then this process will always produce a result.This is all well and good but it is important to get the right types of nutrients to the hair follicle! This part most people tend to ignore. What you eat plays a vital role in the condition of your hair.Which nutrients work best for maximum black hair growth?One of the best ways to get your hair to grow faster is not just to eat food rich in amino acids, vitamins and other minerals like zinc but is also to use hair products that contain amino acids in them.The reason's very simple, hair is made up of a protein and proteins are made of amino acids. When you give your hair more amino acids, it can't help but grow.Here is an example of the types of foods rich in protein:Protein Eating food rich in protein will help your hair grow faster because hair is made up of mainly protein.
