Hair help!!!

Tay

Hi Ladies! I’m wondering what would be the best box dye to get my hair to my natural color all over. I haven’t used box dye in so long so I’m a bit nervous. But I don’t have time to make an appt to go get my hair done. I just don’t want it to come out so dark. My hair is a natural dark blonde. Right now I have lighter blonde balayage but it’s too brassy and I’m over it. I don’t wash my hair everyday and when I did I used the purple shampoo and it helped but dried my hair out so bad. So I’ve quit washing it so much. Any advice please!!!
