loreal and herbal essences do a line of temporary foam hair dyes that don't contain ammonia and only last a week or so. i used to use the red ones a lot. the black might stain if you're naturally blonde though.

i am i wouldnt go black just like a darkish brown....as long as it will wash away...

Not all henna contains metallic salts. Only the bad ones You should look for Body art quality (BAQ) henna. It's probably the best quality there is and it won't turn your hair green or something
BUT henna is a permanent hair dye...but if you don't have any problems with that, henna is a good choice to make you hair darker.
Remember, henna dyes your hair red, so if you want a brown/black colour you should add some BAQ indigo to your henna mix.

You can also use some herbs to darken your hair. Like rosemary, thyme and common sage. But you have to use them frequently for al long time before you see the (subtile) difference.

And yes, I've tried all this myself!

parsley, sage, rosemary and thyme...

[sorry, i had to! haha]
