The most effective hair growth vitamins tend to be the same ones that nourish all of the cells and tissues of the body by helping it to create protein. This is because human hair is made up of almost 100% protein.

Hair follicles require a constant supply of amino acids to build the protein that is needed for hair growth. Hair follicles contain some of the fastest growing and dividing cells in the body so their energy, vitamin, mineral, and amino acid consumption is high. If amino acids are lacking hair follicles simply get the order from the brain to stop creating new hair cells and conserve reserves of protein.

The best hair growth vitamins are all of the vitamins in the B family because they supply amino acids with most of the amino acids that you need to make enough protein to create new hair.  Proteins are absolutely necessary to growing a healthy, beautiful head of hair. It is easier than you might think to become protein deficient. Protein is not stored in the body and we must get them through nourishing ourselves well on a daily basis. The main complete source of these vitamins is meat.  The vegetable world and dairy world has incomplete sources which is why sometimes hair growth vitamins are necessary.

All of the B Vitamins are absolutely essential for hair growth but you really want to make sure that any formula you take contains PABA, Inositol, Choline and Biotin.  Vitamin B12 is also essential for healthy hair growth and if you are not getting enough then your hair could even start falling out.

If you are watching a lot of your hair circle down the drain or see it being caught in your hairbrush it is possible that you are suffering from a lack of biotin in your diet.  It is found naturally in egg yolks but so many women are on diets that require they only eat egg whites that they do not get enough biotin. If your hair is dry and flaky and growing very slowly then a lack of biotin can be the culprit.

If you feel that your body is somehow not metabolizing vitamins in a way that helps you grow hair then you might try supplementing with a good comprehensive amino acid supplement that includes Cysteine Valine, Tryptophan, Threonine, Isoleucine, Methionine, Histidine, Arginine, Lysine and Leucine.  Of all of these Cysteine is one of the most important because it helps your body manufacture the sulfur compounds that are essential for your hair to grow strong.

Another option is to get vitamin injections. Your doctor can test the levels of your blood to see if you need Vitamin B injections to correct any imbalance in your body. Many people are deficient in Vitamin B as well as iron and folic acid.

So the bottom line is that if you are taking hair growth vitamins and they just don’t seem to be that effective then try supplementation with an amino acids formula that also includes cysteine.
