For years, women of all races with beautiful, vibrant hair would tell me that they always take their biotin every morning. After reading the benefits of this "vitamin," every woman should be adding this dietary supplement into their daily routine. Apparently, if you are eating restaurant foods alot or eating a lot of packaged foods, then you may be deficient. Biotin helps to maintain healthy hair and skin!
