Keeps its promises!
I have been using this collagen protein powder for the last 3-4 years, though not this brand because it was not available.  This is a product that absolutely lives up to its claims! After a few months of using this  you will notice a lot of little hairs growing out around your hairline and this is happening all over your head,  it just isn't noticeable for a while. It really does grow hair (revives old follicles??)  and makes your fingernails super hard. I'm not sure how long it was before I noticed that my nails were harder, but it was very obvious when I had to trim them.  When I have read reviews in the past for products like this one, there were claims that, if you have white or gray hair, it will begin growing out dark again.  It happened to me! My hair was pure white/silver (I am 60) and it began getting dark brown, it is now pretty dark in the back and salt and pepper all over. I posted photos of this on Amazon for the brand that I was using at the time and I will try to find them and post them here.  My only problem is that I really liked my white hair! Lol.  I must say, though,  my hair is a lot thicker and shinier after using the collagen and when I stopped using it for a few months (I ran out and put off re-ordering), I began to see a lot more hairs in my hairbrush,  a real bummer.  Just imagine what your body must be missing in the way of nutrients if it has such a drastic effect on your hair! I have read that nutritional deficiencies show up in the hair first and I believe it's true. You won't be disappointed in this product,  I highly recommend it!
