Shampoo or conditioner to darken hair? Coffee or tea?

[anon123]

So I was wondering if there's a shampoo or conditioner you can buy that will darken your hair a bit. I know about indigo, but that seems like a lot of work, esp. since I read you have to henna first and then do indigo on top of it (do we have a tired smiley?). I'd rather have something really simple and quick.

Failing that, has anyone here had success with coffee or tea?

When I was relaxed I used a henna shampoo you were supposed to leave in for 5 minutes then rinse out to achieve black highlights. It darkened my greys and hair quite well. I have tried other henna shampoos and none worked as well as this one. It's by a company called Natur Vital.
Here is a link.

I used the one on the far left for black hair. Though I live in the UK I am pretty sure you can find this in some BSS in the states.
