My son was at one of our US Military Academies and home on leave. He's a natural blond but had been wearing a hat so much his hair was getting darker. I agreed to 'lighten' it for him. It came out a lovely peach color...not a natural tone and one he would get in big trouble for. Called the company and they told us to put Head and Shoulders on his dry hair for half an hour and then wash it out. Let us know how it turns out!
