Bleached Blonde went dark...wanna go back

It's been two weeks and my hair has lightened some but it's just not me!  So today I'm going back.  My hairstylist has suggested highlights.  I'm thinking I wanna go lighter all over then add highlights.  I'll let you know how it goes.

Thanks for the response Susan....I've been washing it with Head & Shoulders and actually the gray is disappearing some.  Now it's just brown, which I don't really like either.  I'm going to keep it this way for a few weeks but I want to go lighter.  Should I just get lots of highlights or start over with a lighter bleach job?  I'll try to remember to take a picture when I get home so you can see where I'm at... I miss being blonde!!  Thanks!

I apologize in advance for my novel here but I want some advice...So here's my dilemma.  I have been bleaching my hair for years (usually with Loreal #9.5 NB) and at the beginning of this year I decided I wanted to go natural (which would be a medium brown) so I could have long healthy hair.  I let my roots grow for a couple of months then went to a salon and had hilights and low lights put in my hair to help conceal the growing out process.  I loved it!  I let my hair grow until last Wed. (from April16 to Nov 16 - 7 months).  The roots were pretty dark underneath but I still had this top layer of blonde that I just wanted to get rid of.  My hairdresser said I should color all over close to my natural color then get some blonde highlights.  I trusted her so that's what we did.  I did not like it when the color was dry - it looked like a dark gray where the blonde used to be.  It actually looks ok (although darker than I want) where the new growth was but what you mostly see is the top, sides, and back where the old blonde bleached hair has turned gray.  I don't feel pretty anymore...is that silly?  I don't have to be bleached blonde but I want a light shiny brown or dark blonde color that looks healthy.  What's my next step?  I do trust my hairdresser...she says "you can always fix color" but I want to have a hold on what should happen before I go in.  My main concern is doing the least amount of damage since I want my hair to grow long.  Any suggestions??
