Since we're friends I can show y'all my roots....
THIS is what I am currently using to color my hair...Revlon colorsilk in Black #10. This is ONLY $2.99 and works like a charm!!
AFTER (and sans make-up)
I also should mention another lil trick and tip I have up my sleeve....In between coloring when I have lil bits of grey showing through I use a black SHARPIE to touch up my roots. No JOKE!!! Again - I know this won't work for everyone BUT if you have dark hair (even brown) get a sharpie and touch up those roots!!
