Just got home from Salon Verve. It is one of the cleanest salons I have been in. They truly know their ingredients. I was really suprized when I walked in because not only was I greeted with a smile and given a tour of the salon, but there was not that over powering chemical smell. They do not allow SLS or ammonia in the salon which really does make it a more pleasent experiance. The color is amazing. No smell, looks great, and no smell.
