A simple breakdown of vitamins for those of you who are a little unsure of what they are. Vitamins are basically proteins and minerals the body uses to as building blocks (like legos they come in all kinds of different shapes and sizes) to build everything from hair to DNA to brain matter. When you are missing one of the essential vitamins in your diet sometimes its possible for the body to compensate for that building block by breaking down others and creating it manually and sometimes its not (iodine is absolutely necessary for proper thyroid function, thus football sized goiters when iodine is deficient).
Similarly vitamins for hair growth are necessary for good skin and hair. There are over 10 vitamins that are essential for efficient and optimal hair growth. One of those that we can focus on just as an example would be biotin hair growth. Biotin is also known as vitamins B7. All of the B vitamins are labeled such because they combine to form the B complex which is just a big combination of all the B vitamins. The body then uses the B complex to help with the metabolic process (breaking down food and changing it into usable energy sources by the body).
When the body doesn’t have a constant biotin supply, the B complex can’t be created and metabolic processes slow. Now we aren’t 100% sure why, but this seems to affect the skin and hair more than other parts of the body, possibly because as the metabolism slows the body focuses energy and vitamin resources on more essential organs (heart, brain, lungs).
But most of you may be asking if biotin deficiency is common? It is more common now days than ever before since biotin is usually attained through whole grains, which are rare in our diet. (Processes such as bleaching flour into white flour strip biotin from wheat)
