Bleaching My Henna'd Hair Blonde?

Tomorrow I have an appointment at the salon. So this is being done professionally.
I henna'd my hair about 4 months ago, and since then I used a medium ash brown color over it about two months ago. I bought some powder bleach and cream developer to do a couple streaks as a test. The hair came out a caramel blonde with some orange undertones. I did not use a toner. Do you think I will be able to (professionally) achieve a blonde color (almost an ombre effect from dishwater blonde to light honey blonde like this http://images5.fanpop.com/image/photos/31400000/taylor-taylor-swift-31491615-1920-1200.jpg) considering that it turned out light orangey caramel with a home bleach kit and no toner or purple shampoo? I am doing an oil treatment now to prepare my hair for some damage. But other than that, think it will work?

Only orange undertones? Should be fine, tell your stylist you've used pure henna in the past, and you're already certain it contained no metallic salts, so they will know to correct for orange when they do your color.
