well many people dye their own hair at quite a young age so when ever you like, i had mine first done when I was 12 but don't ever dye your hair straight away, make sure you do the allergy skin test 2 days before applying the hair dye or you may not know that your allergic and will have an allergic reaction, which isn't nice.
Yes there is no age requirement
It largely depends on the volume of the hair, but in general, about 12-15 cc hair dye per square inch of hair.
Well it is proven that hair dye is unhealth for you hair...if... you use it as a young child or young adult best age to start using hair dye is age 35 most of the time if you use hair dye under the age of 35 your hair will begin to fall out at an early age and turn gray earlier than that even because you hair is young and the color vesles are not fully developed

yes 15 is a good age
it depends you hair color because if your hair color is dark you wont notice the dye at all no matter how many times you dye it but if your hair is light then you might be dying it incorrectly. me personally i wouldn't dye my hair because it damages your hair and you get gray hairs at an early age.
You do not have to be a certain age but if you dye your hair make sure you stay with only one color.If you do not your scalp will become itchy.15
if your hair colour is light, you can dye your hair with henna. If it's not too light like brown hair or black- it can make a slight difference.
