Thank you. I don't want to lift my color at all - only want to deposit color on gray and enrich the rest of my color. Which developer would I use? Would a 10 be strong enough to cover gray? My main concern is that if too much peroxide is used, after the color fades, I'll be left with a brassy/orange color. Every natural hair color I've ever used in the past has left my hair brassy in a few weeks. I have light/med brown hair and am looking to stay the same color. Thank you!! :)
