Hairdresser?!

Anna

So i let my roots grow out way too long and now since I’m pregnant with baby two I won’t have tome to go to the salon every 4 weeks anymore. I want to go back to my natural dark blonde hair ... what’s the best process for this. I know as far as I need to get warm tones back in my hair before I put the hair dye in.... I also know I’m between a 6n and a 6g natural hair color. bht what are the best products and procedures for this?Pictures for show
