I need help on my science project. I am doing Hair Dye VS Hydrogen Peroxide: What are the affects the two will cause of the hair strength. How do I get started. Im lost. Never done a science project before. Need any and all help possible. Thanks in advance!

What level in school are you? This may be far more complex than you supposed.
I suggest you get in contact with someone in a hair care company. They might well be happy to help a student. They know of tests you can perform to do your study, some may be easily adapted to amateur use.
Otherwise: Where do you get the hair? (Beauty salon, I suppose) How long should the hairs be? How many do you test at one time>, ETC, ETC.
Good luck!
