Hair crisis, husband loves it at least

Kristine
just got my  my hair dyed  yesterday to make it one color because my highlights were not what I wanted to orangey. My sister did it way darker than I wanted it. My hair is originally brown but this is dark dark brown. Is there anyway to get it lighter? Just wait a few days? I've used anti dandruff shampoo and baking soda and seems like a lot is coming out but doesn't look any different:(.  The first pic is my natural hair color before I did anything to it the 2nd is right after she colored it. 
Any hope?
My husband loves it but I still have my opinion and know how I feel about it and don't love it
