Hair was blonde, highlighted it and it had splotches in it, cover it with hair color that was a brown color.  Left it alone and brown color started washing out after three weeks.  It was a semi-permanent.  Put on 9G semi-permanent and it turned really dark and grayish blue color.  Can I strip my color out and then put a semi blonde on? 

I have a product called Color Oops!  Hair Color removal extra strength.  Says it has no bleach or ammonia.  Takes 20 minutes and can re-color the same day.  Any body use it before?  Or is there another product or suggestion?  I look like my hair is fake since the color is not a normal shade or that anyone would have picked this ugly color.  Please help.

I've never seen Color Oops discussed on the board. You might try a search on the name on the board's search bar.  The color remover I've seen most favorably mentioned is Colorfix.  I think people get it from Sally's. 

I know you've had troubles recently with your hair color -- I remember reading your previous posts.  You might want to consider re-reading Claude's sticky post (at the top of the message board) on haircoloring.  Some things you'll need to think about in planning the next step...

1. The colorfix will probably leave red/gold tones in your hair.  That seems to be what most people mention.  So you'll need to combat those tones with a color that will counteract -- in Claude's post you'll be able to determine what colors you'll need to look for in the color.
2. You need to decide what level of lightness you want.  You may find out that after the colorfix, you still want to be lighter.  I would think that if that's the case, you'll need to lighten with 20 or 30% developer.  Again, Claude's post will help you understand what color tones will be exposed at the level you ultimately select.  Remember you will need to counteract the tones exposed at the final level, not the level from which you start. 
3. You also need to decide what type of tone you want in your hair at the final level.  For instance, golden, ash, or natural.  Then you'll need to select a color that will provide your desired tone and counteract any of the exposed tones resulting from the lightening.  Again, Claude's post outlines the process very well.

As a quick example, I lighten to a level that exposes a golden color.  I want to be a natural blonde.  To counteract the exposed color, I use a haircolor with a blue-violet base to which I add some drops of red-gold corrector as an added boost (since my hair "throws" a lot of gold -- must have natural red/gold in my level 6 hair).

Above all, strand test.  Mix just tablespoon of color and tablespoon of developer to test a small section of hair before doing your whole head.  You'll save yourself from lots of heartache and potential damage to your hair (through mistakes that need to be corrected). 

Try talking with the manager at a Sally's for additional help.  Some of the staff is knowledgeable, others not so much.  I have found that varying the time, I go in gets me another person to chat with and gain additional insight (that's how I found the red/gold corrector).   Good luck!  Maria
