The chemical preservative kills bacteria, but it's also a known carcinogen that irritates the eyes and respiratory system and can cause skin inflammation.

2. Nut and Seed Oils
Jojoba, avocado, and shea naturally add moisture and shine to hair while also removing oily build up.
3. Acidic ingredients
Sodium citrate or citric acid helps keep shampoo at the right pH balance to wash away dirt and oil while also causing hair cuticles to lie flat so hair looks shiny and smooth.
