There isn't a list of ingredients to avoid for TRs. It is for Keratin Straighteners. That ingredient is Sodium Chloride.
There are natural and synthetic surfactants (sudsing agents) in shampoo. The closer you are to natural, the better it is for your hair and scalp. I usually suggest my clients stay away from Sodium Lauryl Sulfate and Sodium Laureth Sulfate. These are large molecule surfactants.
