So I got my hair dyed on September 2nd of this month. I was a dirty blonde with some natural blonde highlights. I told my hair dresser that I wanted to go a very dark brown and as ashy/cool as possible. I explained to her that I wanted it to be too dark rather than too light and that I also didn't want any brassy/orange undertones to come out once it faded (which I expected to be in two months or so). She assured me that the color was as ashy as possible. In less than a week I felt like my color had completely washed out and my hair is so brassy. I spent over $115 in the salon getting this all over color, which is priced on their website as $65. She ran out halfway through, so I assumed she charged me extra for having to make more product. If not, I was billed for her trimming and then blowdrying my hair afterwards ($50?????). If I would have known, I would have told her to leave my dead ends and I would have walked out with dripping wet hair. The last time I went to this salon, the lady I saw washed may hair, cut off over 10 inches, layered it, blow dryed it, and straightened it for $15. Things are really just not adding up here. She was also bugging me about buying sulfate free shampoo/conditioner for another $50 and I explained that I have sulfate free conditioner at home which I've used every time I washed my hair since I got it done (with regular shampoo). I don't think its normal for this color to have washed out in less than a month. Any advice for what I should do?
