I have been using John Frieda Go Blonder for probably about a month now so I thought I would do a formal review. I really like the product. I wanted my hair to lighten up a bit, which is why I was initially drawn to the product. I am very please with the results (see before/after pics below). The product lathers nicely and it has a pleasant smell. I know some others have complained of a skin/scalp irritation but I have had no problems with this (and I have very sensitive skin). Overall, I would definitely recommend this product for blondes if you just want to get your hair a shade lighter. If you have any questions post them below and I will get back to you.
