I dye my hair. Frequently. I'm one who suffers from premature graying. I have so much gray hair now, that I think it's bordering on 50/50. Not fun for me, when I'm trying to be young and hip.
So, about every three months, when I see so much gray that I can't take it anymore, I dye my hair. I like to highlight it in the same tone as the hair color, so here are my two boxes, and I use the entire bottle of dye because of how thick my hair is. When it gets longer, I have to buy two boxes. Drama Drama.
I like my hair to be as close to my natural color as possible, so I choose a dark auburn brown. I love it!
