If you are a salon client or a hairdresser who deals with a keratin treatment very rarely, then you don’t have reasons to be worried. But if you constantly have to perform the treatment, you should keep in your mind that this procedure can be dangerous for your health. The point is that most keratin treatments have formaldehyde.
So while you are drying or ironing hair, the volume of formaldehyde in the air increases. In this case, some people may have eye irritation or a rash. If it happens the specialist is supposed to stop using the keratin treatment. It’s also advised to choose a professional product from a reliable source, such as Brasil Cacau Keratin Treatment, read its Safety Data Sheet, and always work in a well-ventilated room with gloves.
