I'm a natural blonde wanted to go brunette the brown that the first hairstylist did I did not like so I coloured it dark brown black, too dark so I went to the 2nd hairstylist and asked them to lift the colour, and colour it a dark brown. My hair has red highlights now. I just want to be a dark brunette for winter what shall I do?? Can I put a dark brown on this??

Yes, you can use a dark brown hair over the red highlights. It's much easier to go darker than it is to go lighter.
