Brown to blonde

my hair is naturally dark blonde, but I had highlights that made it almost platinum blonde for years. about a year ago, I dyed it dark brown professionally. I re-dye pretty often because it fades quickly and turns sort of orange. I want to go back to...

very light blonde, and im wondering if its too over processed to do, or if it is possible to achieve in one sitting, profesionally.

it will take a few hours .but they should be able to get it done in one sitting.

They will probably have to bleach it, if you want it really blonde! And it will dry your hair out really bad, so I would go get a bottle of MASK which is a deep conditionar, it keeps your hair from drying out. its about $6 at walmart and it will help big time, it softens and keeps your hair from breaking! But other than that they shouldnt have a problem... I dye my hair dark brown, and back to blonde all the time! Good luck hope I helped

they should get it done in one sitting yes.
