i have been given hair dyes and hair colours as my bio investigatory project!...can you give me a ppt. or a word file on this ?
First look up the word 'investigatory' in the dictionary.

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.
