3. Is It Dangerous?
There have been a ton of talk and a lot of facts about a Brazilian blow-out thrown around suggesting that it is dangerous. This all boils down to the salon that you go to. After all, if the salon is not using the right mixture of chemicals, it can absolutely be dangerous. This is why you do have to be aware of what you are getting into before you go to the salon. One of the chemicals that has been extremely controversial about this particular hair treatment is Formaldehyde. Formaldehyde is a chemical that is used as a preservative, an embalming agent and a disinfectant, and it typically is used in a Brazilian blow-out, as it can actually modify the hair proteins, called keratins. This in turn can cause the hair to turn back to its smooth and not frizzy state.
