No.
First look up the word 'investigatory' in the dictionary.
what do you mean..???
They mean that at least part of the assigment ("investigate") is to dig for information on your topic. What you requested (at least sounded like) you wanted someone to just give you answers.
If I were you, I'd start looking through Wikipedia on hair color looking for what makes hair particular colors, what chemicals are in different hair dyes (or how they work), etc. I'm newer than the others in the forums here, so I may be breaking a rule by even telling you to do that much.
a good opportunity to use this good old website:
