This is a common question. Of course, it is important to have a healthy diet and eat healthy grains, proteins, fruits and vegetables. You are what you eat! However, it is almost impossible to get the amount of biotin in hair vitamins from your normal diet. Dermatologists have always recommended 3000 micrograms of biotin daily to enhance hair growth and to strengthen hair. So where can you find enough biotin in foods to meet that recommendation? Well eggs are one the foods with the highest amount of biotin. One large egg contains 27micrograms of biotin. BUT did you know you would have to eat 111 eggs to get the same dose of biotin in your hair vitamin? That’s a lot of eggs! It is not surprising that in a normal diet, most people consume only 35-70 micrograms of biotin daily. So if you want to grow longer, stronger hair, in addition to a well balanced diet, you should take a hair vitamin that contains biotin. There are no known side effects of biotin so there really should be no downside to taking this vitamin to grow your hair.
