Meinzzfuture,
Have you ever colored your hair black before?
Because a lot of times black hair color can look
too dark. Even on people with naturally black hair, because
the color of your natural hair is usually somewhat
lighter than the black in a dye.
When I colored my hair black (experience I posted about in post above) my hair
was so black that everyone used to ask me, "you colored your hair BLACK?"
And I have black natural hair. But, then again, this was a permanent color. Maybe the semi-perms come out a little lighter. Ask LondonDiva; she colors her hair black with Adore in Jet Black.
Yes, in answer to your question, Sebastian makes a black color. But, I think you should try
a dark brown first (Sebastian Cocoa Brown). Depending on your hair's porosity, even the
Cocoa Brown might come out very dark. So, if I were you, I'd go dark brown first, then if that was
too light, only then would I put in a black color.
