I’m in my early 40s and I purchased Collagen Boost with the hopes of slowing the aging process of my skin. What I was not expecting was how quickly and how strong my nails would get! Usually when it gets cold and dry in the Northeast, my nails get brittle and impossible to grow, and this could not be further from the truth since I started Collagen Boost. Now I’m on my second bag, and I’m noticing new hair growth! I am fortunate to have really thick hair already so this was an unintended outcome. It’s wild to see new hairs around my hairline, almost as long as bangs, that weren’t there before. My husband wants to start using this now in the hopes he can fill out his thinning hair. I’m shocked. I hope it works this well for everyone!
