I am a freshman in college, and I need to develop my own experiment. I was hoping to come up with something original (for example one year, a person wanted to know why people used specific salt to cover roads in winter, so he ended up making his own snow).
Right now I'm thinking something with hair products, like relaxers, dies, perms, keratin treatments and how it affects hair what happens chemically.
I'm having trouble developing the idea further, so if anyone could help I would really appreciate it!!!
Other ideas are welcome also =)
