Go investigate what's in your shampoo, conditioner and body wash. (Go get those bottles right now if you're at home!) If you see something you can't pronounce consider stopping by your local health food store (or regular drug store these days) and picking up some new natural hair and body care products. The scents are delicious they work just as good as the chemical laden stuff you're used to. As for your investigation, let me know what you find out! I've done my own research and quickly switched myself!
Rule of thumb, ingredients should be simple, easy to pronounce (in most cases) and the list should be short.
