Jan 02, 2013 - I like how this keeps my curls defined and shiny, but it does weigh my hair down a bit. DevaCurl is the first line of products I used since discovering how important moisture is for curly hair. As much as I appreciate the end result and the removal of parabens and sulfates and silicone, I'm very concerned, as everyone should be, about toxic chemicals in cosmetic products. We use these every day for years, so it's important to make sure that there are zero toxic ingredients in them. The Deva line, although safer than most, still includes chemicals that are known hazards, so I won't continue to use the products unless they are reformulated with safer ingredients. That said, I like how my hair looks with the Deva products.
