s much as you want. It depends how dark you want it. Coffee seems to be an inexpensive, tightfisted way of dying your hair.
Yes it will dye your hair black(depending on how long you leave it in). I is great if you want a brunet hair color. just dont leave the coffee in your hair as long
Coffee and black tea can be used to naturally dye your hair black.
You should find the nearest hair salon and ask where to get some hair dye or if they have any hair dye.
There is no color you "should" dye your hair...it's whatever color you want to dye it!
I am not going to recommend this as I don't know about the health effects but Coffee stains and can colour your hair, for how long I don't know.
I think you should dye your hair after swimming because the hair salon would probably wash your hair for you if you ask them ($8) and when your hair is not bleached again (water in a swimming pool) after you dye it, it should hold up much better.
As long as their are no chemicals (such as bleach) in your hair dye, then you can't dye your hair too much. A brand I know, that doesn't have any chemicals in the hair dye, is Manic Panic.
No, you should not dye your hair purple. Why? Because if you dye your hair purple you might look like someone/something threw-up on your head.
You should wait at least a month to dye your hair after surgery.
only if you dye your hair frequently,if not it wont bother it as much
