I've been taking this supplement for about two and half months...I'm a woman of a certain age, whose hair is sadly not the gorgeous, thick, luxurious mane of yester-year...insert major sad face here.But these vitamins might actually be helping y'all! OK, what I've noticed, I'm not LOSING hair like I usually do AND my hair actually "feels" different too.! My stylist actually noticed, cuz she asked me if I had been doing something different, because the texture of my hair was different...WOW!So...3+ months later and YES these vitamins are actually helping me! My hair is much thicker/stronger,etc. than it was back in June! What a difference three (3) months can make! I don't know if these vitamins will work this well for everyone, but they have really, really, made a huge difference for me.Good Luck!
