Brazilian hair straighteners
We are aware that there is much confusion around these types of product owing to mixed messages on what ingredients can or can't be used, different claims about what ingredients are actually being used and products falsely claiming to be "formaldehyde free". Many different ingredient names are also being discussed on the internet.
"Brazilian" hair straightening products will be illegal if they contain formaldehyde. Formaldehyde was banned in cosmetic products in 2019 by the strict EU and UK cosmetic safety laws.
