Keratin hair treatments AKA Brazilian Blowouts can make your hair super smooth ♀️ but they could also be harming your health.
A lot of professional keratin treatments can rely ingredients like formaldehyde, formalin, or methylene glycol to straighten hair, but these chemicals can also lead to pretty bad eye, lung, or nose irritation . High levels of exposure (AKA the stylist doing multiple treatments a day) may be at a higher risk for certain types of cancer. Be sure to avoid these chemicals in any of your hair products or treatments!
