Have you ever colored your hair? Hair coloring, or hair dyeing, is the practice of changing the hair color :)
I see. No i have not. But i will like to know the process involved 
OK, well..  Hair coloring can be done professionally by a hairdresser or independently at home; most of the time it's done at home to save money
I see. When did this start and where did it originate
I'm unsure of the history but I think it dates back to anicent roman/greece 
Hmmm. Have you ever done it before?
Yes I have a few times... hair coloring is very popular, with 75% of women and 18% of men living in Copenhagen having reported using hair dye according to a study by the University of Copenhagen.
I see. Is there any psychological effect of hair dye? 
Not that I know of
