Dying gray hair blonde

I have dyed my completely gray head of hair brown for years, and am now considering going blonde. I will obviously have to strip my hair of the brown dye first and go from there, as it would take forever to let the gray grow out . Has anyone out there...

gone through this process, and how did it turn out? What shade of blonde works best on gray?

Blonde ??? why??? You should go to a hairdresser first because you don't want mistakes...wierd colors...

I'm not sure why. Probably because I'm bored out of my skull and need a change, and going blonde would be a huge change. It just sounds fun. I'm tired of the same old same old. I will definetely go to a hairdresser. I have never stripped my hair before and it sounds really harsh. My hair is burnt enough from dying it every month for the last 20 years.
