I can't even imagine that people dont think these really help. I am 52 and not in good health. Diabetes 30 years, Ovarian cancer and all the fun stuff that those bring. My nails, that always grew strong looked terrible and my hair looked like sh** . I started taking these because I saw rave reviews from real cancer patients that had to go through chemo. They were all taking A LOT a day, so I said screw it. I grab a handful every day...5, 6, 7 and I can see a difference. Especially when I brush my hair. I've been doing it for years. Maybe, if your hair is nice to begin with, you don't see a difference as much as people with not that nice hair, but I'm telling you, it does something so you should keep it up! Good luck
