Hi. I had a thread about this color last week. I'll bump it up for ya!.....
edited to add: I see that you want to try the Double Espresso color. Even though I used the Midnight color, this brand has real staying power and that's not what I was looking for at the time. .......
*I was just in the middle of searching the archived threads via the search engine when I found your post lol.* During my search just now, I see that many ladies found black rinses to last a loooong time. I was LOOKING for a rinse that had zero peroxide and zero amonia......but the more I think about it, perhaps, that would just wash out TOO fast. I figure, every time I lighten my hair, I'm disappointed with the outcome. Lightened eyebrows looks best with lightened hair and that was too time consuming and risky for me. Black hair might just be the best for me after all.
Fast Forward:....I might just go back to this color.
