Answer Hello Nany: A wave nouveau has a thio base chemical. It is NOT recommended doing a texturizer over a thio base chemical treatment. Your hair will possibly be destroyed. A texturizer is a milder form of relaxer and many times has a sodium base. It is not recommended at all to mix chemicals. It is important that stylists explain the client’s options, how different products and trestments will effect your hair and the difference in results. Also the fact that when you use one chemical you do not want to process with a different chemcial. As a professional and a mentor, I am sorry that this was not explained to you. If you have any other questions, please ask.
