I lost a large part of my hair due to trauma seven years ago. Since then, my hair has never recovered, and I have continued to lose a lot of hair continuously. I have been using the product for just over two months, and after a little more than a month, I started losing significantly less hair. I now lose maybe a fifth of what I did before! For me, one bottle lasts about two weeks, so it costs quite a bit per month. My hair also gets greasy faster. Otherwise, no downsides. The product smells quite strong and "chemical", but the smell disappears as soon as it dries.
