how to mix color to dye my roots-HELP

So the box says 2 parts developer to 1 part dye? 

I always liked to have about 2 oz total to do my roots.  I would do 1 1/2 oz developer and 3/4 oz dye. 

My hairdresser was charging $105 for a root touch up and haircut.  $33 doesn't sound bad to me.  I stopped going, too. 

The color that was being used on your roots was a Medium-- Neutral, or ash, or gold blonde?  Make sure you know the difference before you dye your roots.  Also, don't pull the color through to the ends as it is damaging.  Rather use a demi or a semi when needed to refresh the mid-section and ends.  Hope this helps.  Also, dye is generally mixed 1 parts dye to 1 parts developer.  2 parts developer to 1 part dye sounds like it might be a highlift color? 

Strand test prior to deciding on doing the entire head.

Hi Beachgrl:  I can echo what Rebekah says about strand testing.  Her advice is always sound.  After struggling with home hair color a bit over the last several months, I can say that with the advice of Rebekah (and lots of reading of older posts by other valuable members of this board) - I have found a combination that works for me. 

My newbie advice is this...Go to a Sally's, enlist the help of an employee to help you match your base color at your roots, determine the level and tone of your base color, and then work from there as to the color you'd like to be.  Knowing your true hair color (a.k.a. your roots) will guide you as to what tone of "medium" blonde you need to purchase (like Rebekah said "neutral, ash or gold blonde").  The degree of warmth or coolness in your natural hair color will determine how any applied color will appear on your head.  Just be patient and strand test before you do your whole head -- you can definitely save a lot of heartache by doing so!  Oh, and if you're impatient like me, you can buy more than one bottle of color and do multiple strand tests at a time.  Good luck!

So the salon uses medium blonde on your virgin medium brown roots? 

Medium Brown

Light Brown

Dark Blonde

Medium Blonde

That's four levels of lift...Do you have ashy Medium brown hair?  If so It's just possible that a highlift was being used.  Although I've never heard of a highlift for medium blonde hair before.  I'd take Maria's advice about getting to Sally Beauty and also strand testing a few different colors.  I hope this helps.  Remember that a strand test won't ruin what you have, but it does show how a color will appear on the hair.  Hope this helps.

Not just one strand but enough strands to see what the color will look like.  It's only necessary to do the roots. 

I think the Sally Beauty near you is in NJ
