I dyed my hair right in that timeframe. My last chemo was Feb 1 (05) and I dyed my hair that particular yr's Memorial Day weekend. in 2005, Herceptin wasn't available when I had chemo but I ended up getting Herceptin alone just a few weeks after that. When I went to get the first one (I'd say about mid June that year), my onc walked into the room and stood there and said, "you look so young". And that was all he said (I went light brown too from a very salty look). He didn't say anything else either.
Go for it. I dyed mine myself with a Garnier box but many here will tell you that you should go to the salon and that it doesn't take as well. I still just dye my own hair which is why I don't post a picture of myself
