What is the best store-bought hair dye brand with low odors and little to no metallics? - best hair dye brand

I dyed my hair a color very close to my natural brown, just to cover gray. Recently I dyed my hair in a salon and the color has a strong odor. The designer said he had no ammonia or metals. I can not give time and money to do it professionally every month, so I would find a box good marks. Help!
