The hair loss product reviews you're about to read contain as much data, science and information as we could compile on this core group of treatments. We encourage you to take the time necessary to really understand each product, which type of treatment it is and how it can be applied to your needs. It is also extremely important that you understand the basics of hair loss before you decide on a product. If you are a man, we encourage you to read the Men's Guide to Hair Loss Treatment first, and if you are a woman, please read the Women's Guide to Hair Loss Treatment. Both of those will lead you back here, and you will be much more prepared to decide on a treatment regimen.
