@Suzanne - I'll try and do a post on damaged hair tips soon. Just quickly, the line I used when I fried my hair with solid-colour bleach a few yrs ago was Redken's Extreme line. (This was advised by a hairdresser who I think knew what he was talking about!) The range is here:  http://www.redken.com/products/haircare/extreme

I liked it because my hair is fine and straight so doesn't do well with really heavy products... this one didn't over-moisturize but still did the job.
