No. Drinking coffee has no effect in your hair color. But if you rinse your hair with coffee, it will give make your hair darker.
No.
yes
nope
By not going out in the sun and there are organic shampoos and conditioners that help get your hair darker :) have fun enjoy Also if you make espresso coffee and let it completely cool, pour it on your hair and it will become a few shades darker.
No waxing removes the hair from root, it will grow back lighter and thinner and with continuous use, the hair root will die....
no it can't make your hair darker. It can, however, remove your hair.
Shaving the hair on your head does not make it grow darker. If you have much grey hair before you shave your head, all of your hair will look nearly white when it comes back, but don't panic. As it grows longer, more of your original color will appear among the greys. I've done this several times, to treat my scalp psoriasis.
well not really ... i think if you open your hair then u get darker sideburns and more hair around your neck hope this helped 
no
no it makes your hair lighter
You can get strong black coffee or tea and brew it. Then wash your hair like you always would and turn off the water. Wash your hair with the black coffee or tea and just rinse it. You should put a big bowl under your hair so it can catch the extra of the coffee/tea. Rinse it over and over until you got it just right and then condition.
no the roots make your hair grow when you wash your hair
