It's so funny, I never had any of these worries when buying, I just saw biotin and bought! It was shortly after I became a member of the board and I saw that biotin was important in hair growth, so I walked the aisles of all kinds of beauty supplies, from Sally's to the Asian ones, even drug stores and Wal-Mart and Target. I saw products that said they grew hair or helped with healthy hair, but I did not see any of the hair growing ingredients, such as biotin, niacin, and inositol and that was all I knew at the time. When I saw Surge, I was like yeah I am getting it, it has biotin (and Keratin Protein) , it didn't take long for me to make the decision, because I foundly found the ingredient I was looking for. Now to be truthful, Fantasia IC Hair Strengthener Spray (which is also a fave) has more in it, Biotin, Vitamin B1, B5, Niacin, Hydrolyzed Keratin, and Panthenol, (as well as some of the same ingredients as Surge (so I don't see anything scary about Surge). I guess because it is not a "name brand" or a familiar brand, we should be afraid, but hey, everything has to get it's start, but I do understand, we have had some nightmares in the hair business, just make your own choice, I like the product and all I can do is suggest it.
