This product is 100% sulfate-free and sodium chloride free. We have many customers who use our product specifically because it is safe and works so well for keratin-treated hair (and it contains no sulfates or sodium chloride, which absolutely must be avoided with keratin treatments so the treatment is not stripped).
You may already know that you want to wait 3-4 days (at least 72 hours) before washing your hair or swimming after your keratin treatment. Of course, this really depends on the type of treatment you receive, and your stylist will be able to give you the specific instructions on how to care for it afterward. Please do let us know if you have any questions or if we can assist you as you begin to use the shampoo and conditioner.
