Olaplex No. 4 Bond Maintenance Shampoo
No. No, Olaplex No. 4 Bond Maintenance Shampoo is not sulfate-free.
It lists Sodium Laureth Sulfate.
- Sodium Laureth Sulfate
Why
Sulfates are foaming cleansers such as Sodium Lauryl Sulfate and Sodium Laureth Sulfate. Mineral salts like Magnesium Sulfate are not cleansers and do not count.
No, Olaplex No. 4 Bond Maintenance Shampoo is not sulfate-free. It lists Sodium Laureth Sulfate.
Sodium C14-16 Olefin Sulfonate is a sulfonate, a close cousin of sulfates that is chemically not a sulfate. Some people who avoid sulfates avoid it too.
This is not a safety warning. It is a label fact, useful if you avoid this group on purpose.
