If you have used hair dye in the past with no problems, it should be fine to do it again.
It is depending on what hair dye you get. Make sure not to dye your hair to many times in a month or it may damage your hair.
if you dye your hair many times your hair will get damage, it will get really dry and your hair will fall out also the natural colour of hair hair will fade away and i heard that you can easly get gry hair from all the chemicals.... scary..
i had it in my hair a month ago and i just kept washing it out 2 times a day for a week and it finnaly came out
2 times
no it will damage the hair
Well its depending what kind of dye you are using for your hair, but if you dye your hair over 5 times in a month it may damage your hair. I would use dyes that you have already used in your hair. If you never dyed your hair before you should ask you local hairstylist and see what they think. Most likely your hair will get damaged if you dye your hair over 5-6 times. Be careful of what dye you use!
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.
anytime they want
Yea, I have don't it many times. You can always dye light hair darker, but never try to dye your dark hair light, unless you are going to a professional!
Depends on how many times you wash your hair.
once a month
