need advice badly

You had this done in a salon and it kept coming out too red? You should've said right away that it wasn't the color you wanted. It sounds to me like they're using a dye with way too much red in it. Blonde hair does not naturally have red in it...it's too light. It can have light orange and yellow, but not red. Generally when going from blonde to a dark shade, you add red so it doesn't come out green or gray, but that doesn't necessarily mean it should come out auburn.

I think you should call up whomever dyed your hair and tell him or her that you are unhappy with the color and would like an ash toner put over it. This would generally mean applying an ash brown semi-permanent over your current color to neutralize the red tones. I would say try to negotiate with the salon before trying it at home, but next time, let them know right away if you don't like it. Don't let them keep siphoning money out of you.

My natural colour is mouse blond aided by a few highlights. Last week I wanted to try brunette and after the first application ended up fairly red head, well copper to be exact. I went back again for a darker colour, preferably more of a chocolate colour and I am now a dark auburn (still with reds) but much darker.

I am guessing my hair has red undertones, is there any way of getting rid of those and getting a nice medium chocolate brown with a gold hue as opposed to a red or orange one? Am I better with a bottle from the store as opposed to paying 100 each time? please help!
