HELP!! Hair crisis! Need to know how to tone down a at-home hair dye disaster?

go to a store like target or kmart and get a box of garnier color breaks for light blonde to medium blonde hair. also, go to a beauty supply shop like sally beauty and get some wella color charm toner in "white lady", an applicator bottle and some 20 volume peroxide. garnier color breaks is about $7.00 and color charm AND 20 volume are also around $7.00. the applicator bottle is about $2.00. you will have to single out every one of your highlights and apply some of the color breaks mixture to the highlights where the whitish/yellow ENDS and the flame color begins. don't apply any mixture to the lightest part. leave it on for up to 15 minutes, but you might not have to leave it on that long. leave it long enough so the flame colored parts are close to the same color as the roots. make sure all the highlights are around the same color and none are too yellow. then rinse it out with cool water and shampoo, don't condition. get out and towel dry your hair and begin preparing your toner. pour 4 ounces of 20 volume peroxide into your applicator bottle and empty the entire toner color bottle into it as well. mix it up really well. you will once again have to single out your highlights, while your hair is still damp. then apply your toner to every highlight, but this time apply color from root to tip. leave it on for 30 minutes and rinse and condition. this should make your highlights platinum blonde. if you don't want platinum blonde however, when you're at sally's, get the "princess blonde" toner shade instead. it has a little bit of golden tone to it but looks natural. good luck!
