There are hundreds of herbs and vitamins out there that promise to promote hair growth. It is difficult to separate myth from fact if you are not aware of the science behind balding and hair regrowth. When deciding whether to pay money for special vitamins, visit your physician first. While it is true that Folic Acid, Biotin, and Magnesium have been linked to healthy regrowth, high levels of these vitamins are not good for the body. A physician can properly diagnose whether you have any vitamin deficiencies and subsequently suggest a vitamin.
First of all, you need to remember that hair is a non living tissue in the human body. It is mainly composed of keratin which is a fibrous protein. Now when keratin builds up in the scalp, it will sprout the thing that we call hair.
