I can't stress to you enough to do your own research and second guessing when it comes to purchasing products. Don't you think people that work at beauty retailers should know at least as much if not more than their customers? Call me crazy but I do. My mom went in to Sephora (my poor mom is getting duped a lot as of late) to buy her Pureology Hydrating Shampoo and Conditioner (which they didn't have). Long story short, the sales person on the floor talked her into another brand because "Pureology contains a lot of alcohol" which she told my mom would dry her hair out even further. She also felt my mom's hair and insinuated that Pureology had dried it out. Totally unecessary. Come to find out that yes Pureology conditioner DOES contain Cetyl and Stearyl Alcohol but these are NOT BAD ALCOHOLS. They are fatty alcohols derived from coconut and palm oil and they are used as emulsifiers to mix oil and water in the conditioner that would otherwise separate in the bottle because oil and water do not mix. They are both emulsifiers but Stearyl has two extra carbons and is therefor longer than Cetyl. Basically, they help your conditioner to spread. It is a shame my mom didn't have this scientific information on hand because it would have really shut that girl up and made her look inferior to my mom's expert analysis of the chemical composition of said alcohols. Not that the girls there work on commission but I still don't appreciate her making alarmist statements with no factual background. Not to mention, my mom was shopping at the Sephora where I live and now is back home in her own state and they do not have a Sephora anywhere close to her for her to return her mistake purchase that she ended up not liking. Even though the sales person said she would LOVE IT SO MUCH MORE. Lesson learned.
The bottom line, and reoccurring theme of my posts, is to do your own research, and don't assume just because someone works at a beauty retailer that they know more than you.
